    Introduction

    Which, if any, activelymanaged portfolios can outperform passive benchmarks? Theprevious literature has documented that, on average, the longterm net performance ofactivelymanagedmutualfundsissimilartotheperformanceoftheirbenchmark(withactivelymanaged funds generally underperforming their benchmarks but without strong statisticalsignificance on average).However, some papers argue that some smaller subset of activelymanagedmutual funds that is identifiableexante isable toconsistentlyoutperform,onaverage,overfairlylongperiodsoftime(see,e.g.,Cohen,CovalandPastor,2005;Kacperczyk,Sialm,andZheng,2005;Mamaysky,SpiegelandZhang,2008;KacperczykandSeru,2007;andCremersandPetajisto,2009).Anecessaryconditionfor longtermoutperformance isthattheactivelymanagedportfolioissubstantiallydifferentthanthebenchmark,whichisconsideredinKacperczyk,Sialm,andZheng (2005)andCremersandPetajisto (2009).Both findthatmutualfundswhoseholdingsaremoredifferent fromtheirbenchmarks,onaverageand inthe longterm,outperformtheirbenchmarksnetoffees.Kacperczyk,Sialm,andZheng(2005)consideronly industrybetsusing the IndustryConcentration Index,andCremersandPetajisto (2009)consider all stock positions using Active Share, i.e., the proportion of fund holdings that isdifferentfromthebenchmark.

    FundswithhighActiveSharehave littleoverlapwiththebenchmarkholdingsandthusaretrulyactivelymanaged.MutualfundswithlowActiveShareshavesimilarholdingsastheirbenchmark.CremersandPetajisto(2009)foundthatsuch closet indexfundshavetendedtosignificantlyunderperformtheirbenchmarks(afterfees)inthefuturebyabout1%peryear.Atthe same time, theyalso found that fundswithabove90%ActiveShareoutperformed theirbenchmarksbyabout1%ayear,afterfeesweretakenout.Cremers,Ferreira,MatosandStarks(2014)analyzealargeinternationalsampleofmutualfundsdomiciledin32differentcountries,andlikewisefindthathighActiveSharefundsonaverageoutperformtheirbenchmarksinthefuturewhilelowActiveSharefundsunderperform.

    Inthispaper,weexaminethesourceofthisapparentinvestmentskillbythemostactivemanagers, focusingonhow fundoutperformance isrelatedto fundholdingdurationsorhow

  • frequentlythefundmanagertrades.Exante, it isnotclearwhetherfundswouldgenerallybemore successful throughholding stocks for longperiodsor through frequently changing theportfolio.Ontheonehand,ifmarketsarefairlyinformationefficient,thenanyinformationthatafundmanageristradingonwillbeincorporatedinthemarketquickly.Asaresult,managersmayneedtofrequentlytradeinordertobenefitfromtheirtemporarysuperiorinformation.

    Ontheotherhand, fundmanagersmaybeabletospotmarketmispricingthat isonlyreversedoverlongerperiods,requiringstrongmanagerconvictionandinvestorpatience.Inthiscase,managerswouldonlyoutperformbyholdingstocksover longerperiods.Thisrequiresastrong conviction on the part of themanager, as stock pricesmay initiallymove adverselybeforereversinganymispricing.Similarly, itrequiresthat investorsare fairlypatient ingivingthe manager time to see the strategy through, rather than evaluate the performance arerelatively brief periods of time. An investment approach with long holding durations maybenefit from opportunities to buy relatively illiquid or deepvalue stocks on the cheap (seeAmihud, Mendelson and Pedersen, 2005), at the detriment of potentially allowingoverconfidentfundmanagerstopersistinwrongconvictions.

    Finally,itseemspossibleexantethatbothshorttermandlongtermopportunitiesmaycoexist, and that differentmanagerswith different skills set, convictions and opportunitiesfocusonwhere they think theyhave the strongestadvantage.Whether somemanagersareabletobenefitfromtheirshorttermtradesthatcouldpotentiallyexploittemporarymispricingor shortlived information advantages, and whether other managers can exploit longtermundervaluationorbenefit froman illiquiditypremiumarethusseparatebutrelatedempiricalquestions.

    Theextantempiricalliteraturehasnotdocumentedastronglinkbetweenfundholdingdurations(ortradingfrequency)andsubsequentfundperformance.Wearguethatthereasonforthis,andtheexplanationthatweareabletofindastrongassociation,isthatwedistinguishbetween truly actively managed funds and those whose holdings are fairly similar to thebenchmarks,i.e.,thatwedistinguishbetweenfundswithlowversushighActiveShare.Amongfundswith longholdingdurations,onewillnaturally findboth (closet) index funds and very

    Our basic setup is straightforward. We consider both a large sample of activelymanaged allequity U.S. retail mutual funds from the CRSP Survivorshipfree mutual funddatabase,andthesampleofallaggregatedinstitutionalinvestorportfoliosfromtheirquarterly13F statements. For each sample, we perform 5x5 double sorts of portfolios into holdingduration(orturnover)quintilesandActiveSharequintiles,andthencomparetheperformancealongbothdimensions.Foroursampleofmutual funds,weconsiderthe futureperformanceover the 19year period from 1995 2013, and evaluate the performance of both the netreturns to investorsafterall trading costsand fees (except frontand rearend loads)andoftheir holdingsbased gross returns. For our sample of aggregate institutional portfolios,weanalyzethe longerperiodof19862013,butonlyconsiderholdingsbased grossreturnsaswedonotobservetheiractualafterfeenetreturns.WeevaluateperformanceofthenetaftercosttradingreturnsafterbenchmarkadjustingasmotivatedbyCremers,PetajistoandZitzewitz(2013) generally using the mutual funds selfdeclared benchmarks and evaluate theperformanceofthegrossholdingsbasedreturnsaftercontrollingforsizeandbooktomarketcharacteristicsaccordingtoDaniel,Grinblatt,TitmanandWermers(1997).

    Weemploy threeproxies forhow long fundshold stocks in theirportfolios.The firstproxy istheFundDurationasrecently introduced inCremersandPareek(2013)andCremers,PareekandSautner(2013)attheportfoliolevel.FundDurationmeasurestheweightedaveragelengthoftimethatthefundhasheld$1ofequities intheportfoliooverthe last5years.Thesecondproxyistheholdingsbasedfundturnover,whichwecalculateourselvesforthemutualfund and institutionalquarterlyportfolios as inGaspar,Massa, andMatos (2005). The thirdproxyisonlyavailableforthemutualfundsample,andistheselfdeclaredFundTurnoverRatio,

  • i.e., the ratio of all sales / buys in the calendar year over the number of fund sharesoutstanding.

    ThemedianActiveSharei.e.,theproportionofportfolioweightsthatdoesnotoverlapwithbenchmarkweightsofmutualfundsequals79%inoursample,withahighof86%atthebeginningofoursample in1994anda lowof73% in2002.Funds inthebottomActiveSharequintilegenerallyhaveanActiveSharebelow60%and can thusbe considered closet indexfunds.FundsinthetopActiveSharequintileportfoliohaveanActiveShareofatleast90%,andthushaveholdingsthatarequitedistinctfromtheirbenchmarks.Themedianholdingdurationisourmutualfundsampleequals14months,whilemutualfundsinthebottomFundDurationquintile portfolio hold stocks generally for less than 7 months and those in the top FundDurationquintileformorethan24months.ThecrosssectionofFundDurationshasbeenfairlystableovertime.1

    Ourevidenceshowsthat,amonghighActiveSharefunds,patientlymanagedportfolioshave been most likely to outperform. Patient funds are those which trade relativelyinfrequently, i.e., fundswith longholdingdurationsor lowportfolio turnover.The longtermoutperformance of the highActive Share andpatient funds is economically remarkable. Forexample, letsconsidertheequallyweightedportfolioofmutualfundswhereboththeActiveShareandtheFundDurationareinthetopquintile.Thesepatientfundswereabletobeattheirbenchmarksinthe12monthsfollowingportfolioconstruction,aftercosts,by1.92%peryear(tstatof2.08).Adjustingthebenchmarkadjustednetreturnsforexposuretothestandardfivefactors(market,size,booktomarket,momentumandliquidity)increasestheoutperformanceto 2.30% per year (tstat of 3.14). Compounding this over the 19year period (19952013)producesacumulativeoutperformanceof54%.

    1ThemedianActiveShareforourinstitutioninvestorsampleissimilartothemutualfundsampleat73%,HedgefundsarethemostactivegroupofinstitutionswithamedianActiveShareof84%andpublicpensionfundsaretheleastactivewithamedianActiveShareof21%.HedgeFundsarealsothemostshorttermwithamedianFundDurationof0.75 yearsandpublicpension fundsare themost longtermwithamedian FundDurationof2.41years.

  • Similarly, the stocks held by high Active Share and patient institutional portfoliosoutperformby2.22%peryearonaverage(tstatisticof4.10),whichcompoundedoverthe27year period (19862012) accumulates to an outperformance of 80%. Finally, among patientinstitutions with high Active Share we find that hedge funds have particularly strongoutperformance,with an annualized alpha of 3.64% (tstatistic of 3.04),which compoundedover the19yearperiod (19942012)aggregates to97%outperformance. Incontrast, there islittleevidencethattheholdingsofhedgefundsgenerallyoutperform(seealsoGriffinandXu,2009).ThisagainhighlightstheimportanceofdistinguishingbetweenhighandlowActiveSharehedge funds, and among highActive Share hedge funds between shortterm and longterminvestors.2

    We findnoevidence thateven themostactive (i.e.,highActiveShare)mutual fundswithshortdurationsorfrequenttradingwereabletooutperformtheirbenchmarksonaverage.Rather, we find that frequently trading mutual funds systematically underperformed theirbenchmarks, regardless of how different their holdings are relative to their benchmark. Forexample, the equallyweighted portfolio ofmutual fundswith short FundDuration and lowActiveShare(both inthefirstquintile)underperformedconsiderablywithanabnormalreturnof2.46%peryear(tstatof5.52).ThemutualfundportfoliowithshortFundDurationandhighActiveSharefundssimilarlyunderperformedwithanannualabnormalreturnof1.94%(tstatof 2.45). This suggests that only active bets that were also patient (or longerterm) wererewarded inthemarkets,whileweactiveshorttermmutualfundbetswereonaveragequiteunprofitable.3

    2Our resultsare robust to removing fromoursample thegroupof institutionswhoseportfoliosaredominated(withportfolioweightsabove90%)byonesinglestockthatisheldlongterm.ExamplesaretheinstitutionalfilingsofAmericanExpressCompany,variousESOPsholdingsalmostexclusively thestockof thesponsoringcompany,andfoundationsandendowmentswhose13Ffilingsalmostexclusivelycontainasinglestock(suchastheGannettFoundation,theGeneralElectricFoundation,theWilliam&FloraHewlettFoundation,theRobertWoodJohnsonFoundation,theKresgeFoundation,theLillyEndowmentandtheUniversityofDelaware).3Forour institutional sample, the stocksheldby institutions (andhedge funds)with shortFundDurationshadinsignificant alphas andDGTWadjusted returns.Naturally, that does notmean that these institutions did notoutperformorunderperform,asweonlyobservetheirholdingsandnot,forexample,theirwithinquarterroundtrip trades. Themore often an institution trades, the less informative about investment skill the quarterendholdingswillbe.Therefore,wecannotconcludeanythingabouttheinvestmentskilloftheshortterminstitutions

  • The lack of profitability from active shortterm bets is consistentwith the literaturearguing that shortterm trading by institutional investors is associated with greater pricingefficiency (see,e.g.,Collins,Gong, andHribar,2003;Ke andRamalingegowda,2005;Bartov,RadhakrishnanandKrinsky,2000;andBoehmerandKelley,2009).This literatureargues thatthestocksinwhichshortterminstitutionstradetendtobeefficientlypricedandthusunlikelyto allow profitable shortterm trades.On the other hand, Puckett and Yan (2011) find thatinstitutionalroundtriptradeswithinthequarteraregenerallyprofitable,estimatingthattheseshortterm trades add about 26 basis points per year on average. However, Chakrabarty,MoultonandTrzcinka (2014),examiningthesamedataasPuckettandYan (2011),documentthat shortterm roundtrip trades ingeneral (i.e.,not limited toonly those thatarewithinacalendarquarter)arenotprofitable.Onecontributionofourpaper istoconsiderthisdebatewithinthecontextofthelargeliteratureonmutualfundperformance.

    Holding stocks for a relatively long period is in itself on average not associatedwithgreater investment skill. Rather, Active Share matters most among funds with long FundDurations,while among fundswith short FundDurations the difference in the performancebetweencloset indexfundsandhighActiveSharefunds iseconomicallysmallandstatisticallyinsignificant. For example and using equalweighting, the longshort portfolio that is long infundswithhighActiveShareand longFundDurationandshorts fundswith lowActiveShareand long Fund Duration has an annualized alpha of 3.47% (tstatistic of 4.78), while theanalogouslongshorthighlowActiveShareportfolioamongshortFundDurationportfolioshasanalphaof0.44%peryear(tstatisticof0.57).

    We try to explain the managerial skill of the high Active Share and patient fundmanagersbyexaminingtheirexposureto7factorssuggestedbytheexistingliterature:market,size, booktomarket, momentum, systematic liquidity, low versus high beta and earningsquality. For the last two factors,we use the recently proposed Betting against Beta (BaB)factor (see Frazzini and Pedersen, 2013) and Qualityminus Junk (QmJ) factor (seeAsness,Frazzini,andPedersen,2013), respectively.We find that these latter two factorscanexplainper se, and only observe that their quarterend holdings do not exhibit any investment skill. See further ourdiscussioninthenextparagraph.

  • mostof theoutperformanceof thepatientandhighActiveSharemanagersofmutual funds,butonlya fairly small fractionof thegrossoutperformanceof the stocks in the institutionalportfolioswithhighActiveShareandlongFundDuration.Specifically,theclearmajorityoftheoutperformanceof thepatientandactivemutual fundmanagers seemsdue to theirpickingsafe (low beta), value (high booktomarket) and quality (profitable, growing, less valuationuncertainty,higherpayout)stocks,and thenstickingwith theirconvictionsandholdingon tothoseover relatively longperiods.Our results thus suggest thatWarrenBuffetts investmentskill (see Frazzini, Kabiller and Pedersen, 2013) seems generally shared by mutual fundmanagersinthetopActiveShareandFundDurationquintiles.

    In conclusion, our results indicate that Active Share and Fund Duration are bothimportantdimensionsofactivemanagement thatstrongly interact inpredicting theabilityoffundmanagers tobeat theirbenchmarksand inpredicting theoutperformanceof thestocksheldininstitutionalportfolios.Whilelongtermfundmanagersingeneralwereunabletobeattheirbenchmark,onlyhighActiveSharemanagerspursuingpatientstrategiesweresuccessful.Thisunderscoresthe importanceofdistinguishingbetweentrulyactivefundsandthosefundswhose holdings have significant overlapping holdings with their benchmarks. Similarly, ourresults highlight the importance of distinguishing among the truly active funds betweenmanagers pursuing shortterm mispricing (generally unsuccessfully in our sample) versusmanagerswho stickwith the courage of their convictions and patiently (and in our samplesuccessfully)followabuyandholdstrategywithadistinctportfolio.

    Stock returns data are obtained from monthly stock data files from the Center forResearch inSecuritiesPrices (CRSP),andaccountingdataare fromCOMPUSTAT.Tocalculatetrackingerror,weusedailymutual fund returns fromStandard&Poorsand theWallStreetWebuntilSeptember1998,andafterwardsfromtheCRSPdailymutualfundreturnsdatabase.The samedata sourceswereused inCremers andPetajisto (2009) to calculatemutual fundtrackingerrors,andseethatpaperfordetails.Thefundtrackingerroristhestandarddeviationofthedifferencebetweenthedailyfundreturnandthedailybenchmarkreturnoverthepast12months.

    Weusemutual fund selfdeclaredbenchmarkswhereveravailable.The sourceof theselfdeclared benchmarks isMorningstarDirect,whichwemerge toour other data by fundticker and/or cusip. As Morningstar Direct makes available only the current selfdeclaredbenchmark and these benchmarks could change over time for a particular fund, we usehistoricalMorningstarDirectdataobtainedin2009,2011and2013,andassumethattheselfdeclared benchmarks in 2009 were applicable also before that year. If the selfdeclaredbenchmark isnotavailable,weassignabenchmarkourselvesbasedon thebenchmark indexthat has the closet fit in terms of holdings (i.e., has the lowest Active Share across allbenchmarks considered). The main advantage of this is that if we assign an incorrectbenchmark in case the selfdeclared benchmark is not available, then that only happensbecause the funds holdings actually resemble that benchmarks holdings more than theholdings of any other benchmark. Another advantage of assigning benchmarks using theminimumActiveShareisthatthisrequiresnoreturnhistoryandcantakeaccountofchangesin

  • the funds style. Finally,we verify that our results are robust to not using the selfdeclaredbenchmarks at all but only using the minimum Active Share benchmarks that we assignourselvesbasedonthemostcurrentholdings.

    The set of benchmarks includes all selfdeclared benchmarks chosen by funds in oursampleasavailableinourMorningstarDirectdata.Thebenchmarksarefromthesebenchmarkfamilies: (1) Calvert Social (1 benchmark), Down Jones (6 benchmarks, including the DJIndustrialAverage, theDJUSSelectDividend, theDJWilshire4500and theDJWilshire5000benchmarks),FTSE (4benchmarks, including theFTSEHighDividendYield,FTSERAFIUS100andMid Small 1500 benchmarks),Mergent (1 benchmark),MSCI (15 benchmarks, includingsmall,mid and large capbenchmarksplus their value and growth components),NASDAQ (2benchmarks,namely theNASDAQ100and theNASDAQCompositebenchmarks),Russell (13benchmarks, including small, mid and large cap benchmarks plus their value and growthcomponents), Standard and Poors (14 benchmarks, including small, mid and large capbenchmarksplus theirvalueandgrowthcomponents),andSchwab (2benchmarks, includingtheSchwab1000andSchwabSmallCapbenchmarks),foratotalof58benchmarks.Weverifythatour resultsare robust tousinga smaller setof19benchmarksasused inCremersandPetajisto(2009),whoonlyincludebenchmarksfromtheRussell,S&PandWilshirefamilies.

    Theholdingsofthevariousbenchmarkscomefromavarietyofsources.FortheRussellandS&Pbenchmarkfamilieswhicharethemostfrequentlyusedasselfdeclaredbenchmarks we have the official benchmark constituent weights, from Russell directly and fromCompustat for S&P. For all other benchmarks, we approximate the benchmark constituentweights by using the weights in passive ETFs and passive mutual funds with the samebenchmarks,averagedoverallavailablepassive fundswithcompleteholdings information inThomson or CRSP, analogous to the methodology in Cremers, Ferreira, Matos and Starks(2014).DailyandmonthlybenchmarkreturnsarefromBloomberg.

    Active Share measures the proportion of the funds holdings (considering only U.S.equitypositions) that isdifferent from theholdingsof the fundsbenchmark at aparticularpointintime.Itiscalculatedasfollows:

    To evaluate the performance of the fund accruing to the endinvestor, we use thebenchmarkadjustedreturnformutualfunds.AsexplainedbyCremers,PetajistoandZitzewitz(2013), subtracting the benchmark return from the netmutual fund return is a simple androbustmethod to adjust for the funds exposure to a particular style or to particular stockcharacteristics.We calculate the fivefactoralphasof thebenchmarkadjustednet returns tocontrol for any remaining exposure to the market, size, booktomarket, momentum andliquidity factors,using thedata for those factors fromKen Frenchswebsite and the tradedliquidity(PastorStambaugh)factorfromWRDS.

    A.MutualFundPerformance

    Adjustingthebenchmarkadjustednetreturnsforexposuretothefivefactors(market,size, booktomarket,momentum and liquidity) increases the outperformance to 2.30% peryear(tstatof3.14),asshown inPanelAofTable4.Valueweightingtheportfoliosofmutualfundsgivessimilarresults,albeitwithweakerstatisticalsignificance(outperformanceof1.86%peryearandatstatof1.66afterbenchmarkadjusting,seePanelDofTable3,andof1.85%peryearandatstatof1.88afteralsoadjustingforexposuretothefivefactors,seePanelBofTable 4). Theweaker statistical significancemay be due to a few large funds dominating aportfoliooffunds,giventhelargeskewinfundsize.

    The most active mutual funds with short durations or who frequently trade weregenerally unable to outperform their benchmarks. Rather, we find that mutual funds thatfrequently trade on average underperformed their benchmarks by a considerable margin,acrossall levelsofActiveShare.Forexample, theequallyweightedportfolioofmutual fundwithshortFundDurationandlowActiveShare(bothinthefirstquintile)underperformedtheirbenchmarksconsiderablywithanabnormalreturnof2.46%peryear(tstatof5.57seePanelAofTable4).Theunderperformanceof theanalogousportfoliowith shortFundDurationandhighActiveShare(inthetopquintile)similarlyunderperformedwithanannualabnormalreturnof1.94%(tstatof2.45,againseePanelAofTable4).Wethusfindthatonlyactivebetsthatwerealsopatient (or longerterm)were rewarded in themarkets,but findnoevidence thatactiveshorttermbetswereprofitable.

    Further,theresultsforoursampleconfirmthatActiveShareisusefulforpickingactivemanagers, but find less evidence that highActive Share alone is generally sufficient to findmanagerswho outperform their benchmarks.We replicate themain result in Cremers andPetajisto(2009)thathighActiveSharefundsoutperformlowActiveSharefunds.However,wedo not find that high Active Share funds as a group have economically and statisticallymeaningfuloutperformance,butonlyhighActiveSharefundsthatalsohavelongerinvestment

  • durations.Unconditionally,thefundsinthetopActiveSharequintiletendtooutperformtheirbenchmarks on average for equallyweighted portfolios, but this outperformance ismodesteconomically (e.g.,25basispointsperyearalpha inPanelAofTable4)andnot statisticallysignificant(tstatisticof0.45).Furthermore,theoutperformanceofthehighActiveSharefundsis on average negative using valueweighted portfolios, showing that large funds with highActiveShare(whoarenaturallyweightedmoreheavily inthevalueweightedportfolios)werelesslikelytooutperform,asalsofoundinCremersandPetajisto(2009).6

    LongerFundDuration isassociatedwithbetterperformance,andespecially for largerfunds. Across all Active Share quintiles, funds with long Fund Duration (top quintile)considerable and statistically significantly outperformed funds with short Fund Duration(bottom quintile) for valueweighted portfolios. The stronger positive association betweenperformanceandFundDuration for larger funds isconsistentwith those larger fundshavingmorepriceimpactwhentheytrade.

    Holding stocks for a relatively long period is in itself on average not associatedwithmanagerialskillorsignificantoutorunderperformance,andtheonlyportfolioswithlongFundDuration that outperform are those that also contain high Active Share funds. Theunconditionalportfolioof funds in the topFundDurationquintilehasaneconomically smallandstatisticallyinsignificantabnormalreturn.ThissuggeststhatthepositiveabnormalreturnsdocumentedbyCremers,SautnerandPareek(2014)forportfoliosofstockssortedbyduration(i.e.,averagingFundDurationoverallfundsowningthestock,usingthedollaramountinvestedbyeachfundinthestockastheweights)isduetothestockselectionskillsofthemostactivefundsratherthantosomestockrelatedanomaly.

    One possible interpretation of these results is that fundmanagerswith very distinctportfolios(i.e.,withhighActiveShare)whoalsotradealotmaybeoverconfident.Alternatively,fundsinthetopActiveSharequintilemaybefocusingonrelativelyilliquidstocks(i.e.,relativeto the stocks in thebenchmark), and frequent trading in those stocksmay significantlyhurtperformance. This would mean that the impatient and very active fund managers aredemandingcostly liquidityprovision.Insubsequentanalysis,wetrytoshedfurther lightuponthesealternativeexplanations.

    Usingeither turnoverproxy,we find that funds that trademore tend tohavegreaterunderperformance,andespeciallysoforfundsthatalsohaveahighActiveShare.First, inthesinglesortonFundTurnoverRatio, theportfolioof funds trading themost (quintile5)hasafivefactoralphaof1.58%peryear(tstatisticof2.81),whilethequintile1portfolioexhibitsnosignificant underperformance (alpha of 0.38% per yearwith a tstatistic of 1.05). Similarly,usingFundHoldingsTurnoversinglesorts,thequintile5portfoliohasanannualizedalphaof1.97% (tstatistic of 4.29) and the quintile 1 portfolio has an annualized alpha of 0.14% (tstatistic of 0.39). In both cases, the difference in performance across the quintile 1 and 5portfoliosisstatisticallysignificantaswell.

    The final robustness check for the main result in this section using net benchmarkadjustedreturnsistorun19annualFamaMacBethpredictivecrosssectionalregressionsoftheyearly net benchmarkadjusted fund return on various fund characteristics,with theirmeancoefficientspresented inTable6.Theseregressionsallowustocontrolforseveralotherfundcharacteristicssuchastrackingerror,the logoffundsizeandtheexpenseratio,andtoverifywhether the outperformance of the funds with high Active Share and relatively infrequenttrading is robust across years.We enable an easy comparison to the portfolio approach byfocusingontheHigh(Low)ActiveSharedummy,whichequals1ifthefundsActiveShareisin the top (bottom)quintile that year,plus the interactionsof these twodummieswith thethreepatienceproxies.Aspreviouslyalsoshown inthedoublesorts,fundperformance inoursample isnot linearlyrelatedtoActiveShareandtheproxiesfortradingfrequency,suchthatusing Active Share itself rather than the dummies does not produce statistically significantresults.

  • Column (1)ofTable6 shows that fundswithhighActiveShare tended tooutperformtheirbenchmarksbyabout79basispoints,thoughwithoutstatisticalsignificance(tstatisticof1.45).Likewise,noneofthe3patienceproxiesaresignificantlypredictiveoffundperformance.InColumn (1),theonly fundcharacteristicstronglyrelatedto future fundperformance istheexpenseratio, indicatingthatmoreexpensivefundsperformedworseonaverage.Column(2)showsapositiveandstatisticallysignificantcoefficientfortheinteractionofHighActiveShareand FundDuration, Column (3) for the interaction ofHigh Active Share and Fund TurnoverRatio,andColumn(4)fortheinteractionofHighActiveShareandFundHoldingsTurnover.Thisconfirms thatonlymutual fundswithhighActiveShare thatalsopursuedpatient investmentstrategieswereabletooutperformtheirbenchmarksinoursample.

    Next,weevaluatethefundperformanceusingtheholdingsbasedgrossreturns,whichis lessrelevanttoend investorsbut is informativeaboutmanagerialskillbeforetradingcostsandotherexpensesare incurred.Asdescribed inSection2,wecalculate theDGTWadjustedholdingsbasedreturns,andcontrol foranyremainingexposure to thestandardmarket,size,booktomarketandmomentumfactors.Table7showstheresultsfortheequallyweighted5x5double sort on Fund Duration and Active Share. One noticeable change from the previousresultsisthatonceweuseDGTWadjustedgrossreturns,wenolongerseemanyportfoliosinthe double sortwith economically and statistically significant negative alphas. This indicatesthatmanymanagershaveon averagemanagerial skill,even if (againon average)notmanyinvestors benefit from those in the form of net performance that is superior to theperformanceofthebenchmark.

    TheonlyportfoliosexhibitingapositiveandstatisticallysignificantalphafortheDGTWadjusted gross returns is the portfolio with high Active Share (quintile 5) and high FundDuration (quintile 5),with an annualized fivefactor alpha of 1.26% (tstatistic of 1.94). Thisconfirmsthemainresultthatactiveandpatient investorsoutperform.BothActiveShareandFundDurationmatter.Similar to theprevious resultsusingnetbenchmarkadjusted returns,fundswith longFundDurationtendtooutperformfundswithshortFundDuration,especiallywhenActiveShare ishigh.Forexample,the longshortportfoliobuying (stocks in)fundswith

    Previously,wehad raised twoalternative interpretationsof theunderperformanceofvery active managers with short investment horizons: overconfidence versus a focus onrelatively illiquid stocks.TheDGTWadjusted gross returns areuseful todistinguishbetweenthesealternative interpretations,asgross returnsarenotaffectedby trading costsor costlyliquiditydemands from impatient trading.Comparing the alphasusingDGTWadjusted grossreturnsinTable7totheanalogousalphasusingbenchmarkadjustednetreturnsinPanelAofTable3suggeststhatlowActiveSharefundslosemoreintradingcostsandotherexpensesthanhighActiveSharefunds.Thiscastsdoubtontheliquidityexplanation.Wewillempiricallyrevisitboth interpretations inSection4,byexploringwhatstrategiesthepatientmanagerswithhighActiveShareusedtosubstantiallyoutperform.

    We thus conclude that themanagerial skill from themost active andpatientmutualfund managers is quite similar to that manifested by Warren Buffett, as documented byFrazzini,KabillerandPedersen (2013).Theydocument thatBerkshireHathaway,managedbyWarren Buffett, as well as Berkshires public equity holdings identified from quarterly 13Fholdingshavesignificantlypositivealphasthatbecome insignificantonlywhencontrolling fortheir exposure to BaB andQmJ.Our results thus indicate thatWarren Buffetts skill seemsgenerallysharedbymutualfundmanagersinthetopActiveShareandFundDurationquintiles:the clearmajorityof theiroutperformance seemsdue to theirpicking safe (lowbeta),value(highbooktomarket)andquality(profitable,growing, lessuncertainty,higherpayout)stocksandholdingontothoseoverrelativelylongperiods.

    4.Conclusion

    This paper documents that both Active Share and trading frequently and theirinteractionare importantdimensionstoexplainandpredicttheabilityofstockportfoliostooutperform. For both retail mutual funds and general institutional portfolios, we find thatamonghighActiveShareportfoliosonly thosewithpatient investmentstrategiesareable tooutperform their benchmarks on average. Funds which trade frequently generallyunderperformtheirbenchmarks,regardlessofActiveShare.

    Thismeans that among funds that infrequently trade, it is crucial to separate closetindex fundswhoseholdings largelyoverlapwiththebenchmark fromtrulyactive fundswhoseholdingsarealmostcompletelydifferentfromtheirbenchmarkswithhighActiveShares.Economically,ourresults indicatesubstantialbenefitsfromthe investmentskillofhighActiveSharemanagersthattradeinfrequently.Theaverageoutperformanceofthemostpatientanddistinctportfolios(usingquintilesorts)equals2.30%peryearnetofcostsforretailmutualfunds(tstatisticof3.14). Compoundingthis2.30%annualoutperformanceoverthe19yearsoverwhichitisestimated(19952013)givesacumulativeoutperformanceof54%.Stocksheldbypatientandactive institutions ingeneraloutperformby2.22%peryear(tstatisticof4.10)andbyhedgefundsinparticularby3.64%peryear(tstatisticof3.04),bothgrossofcosts.

    The average underperformance of retail mutual funds that frequently trade andgenerallyholdstocksforlessthan7monthsarelikewiseeconomicallysubstantial.Forexample,theportfolioofmutualfundswithshortFundDurationand lowActiveShare(both inthefirstquintile)hadanabnormalnet returnof 2.46%peryear (tstatof5.52),which compounded

  • overour19yearperiodfrom19952013wouldaccumulatetoatotallossof38%oftheinitialamountinvestedrelativetoapassiveinvestmentinthemarketatnocost.

    OurresultssuggestthatU.S.stockmarketsmaybetoo informationefficient,withtoomuchcompetitionamongactive investorsortoomuchprice impactof informationtrades,forinvestors to systematically benefit from frequently trading mutual fund managers pursuingshortterm predictability. At the same time, our results also suggest that one can ex anteidentifyadistinctivegroupoffundmanagersthatseemtoexhibitsubstantial investmentskillwhenmeasuredoversufficientlongperiodsoftime.ThisisthegroupofpatientfundmanagersthatsticktotheirconvictionsandcombineahighActiveSharewith infrequenttrading.Inour5x5sortof retailmutual funds, theoutperformance isstrongest in the2portfolioswithhighActiveShare (topquintile)andtop40%ofFundDuration (top2quintiles),constituting8%offundsandonaverageabout6%ofassetsinoursampleofretailmutualfunds.

    How did these patient and active mutual fund managers outperform? Perhapsunsurprisingly, their outperformance can largely be explained by their focus on stocks thatotherinvestorsshunorfindlessattractivefortheirimpatientstrategies:pickingsafe(lowbeta),value (high booktomarket) and high quality (profitable, with growing profit margins, lessuncertainty,higherpayout)stocksandthenstickingwiththoseoverrelativelylongperiods.OurfindingsthussuggestthatWarrenBuffettsinvestmentskill(seeFrazzini,KabillerandPedersen,2013)seemsgenerallysharedbytheseretailmutualfundmanagersinthetopActiveShareandFundDurationquintiles.

    We have less success in explaining the large gross outperformance of institutions especiallyhedge fundswithhighActiveShareand longFundDuration.Thisgroup includesBerkshireHathaway,probably thebest knowpatient investor, formuchofour timeperiod.However,we find thatBerkshireHathawaypublicequityholdings in the last10yearsofoursamplearenolongerverydistinctfromthemarketportfolio(withanActiveSharearound80%since2007andaround70%attheendofoursample in2012).BerkshireHathawayremainsapatient investor in public equities, even though the holding duration of public stocks in thequarterend13FreportsofBerkshireHathawaysportfoliohasshortenedfromover4years in

  • 2002 to a bit over 3 years. Frazzini, Kabiller and Pedersen (2013) show that BerkshireHathaways remarkable performance can largely be explained by exposure to safe and highqualitystocks,whichwe likewisedocumentforpatientandactivemutualfunds.However,wefindthatexposuretolowbeta,booktomarketandqualityfactorsexplainsonlyasmallfractionoftheoutperformanceofthestocksinthequarterendportfoliosofhighActiveShareandlongFundDurationinstitutionsandhedgefundsgenerally.

    We thus leave the the investment skillofpatient institutionswithverydistinctpublicequityportfolioslikeRuaneCunniff&Goldfarb,GardnerRusso&Gardner,SPOPartners&Co,for example, as largely unexplained. The investment skill of the fund managers at theseinstitutionsmaynotbeeasilycapturedinquantitativefactorsormaychangesubstantiallyovertimedependingonthecircumstances.Perhapstheirsuccessdependsonbeingtrulypatientandcontrarian,willing towait yearsbeforedeploying cash in aworldwhere typical institutionalportfolioshave100%turnoverbasedonquarterendholdings(andthusignoringanyroundtriptradingwithinquarters).Relatedly,perhapstheseinstitutionsaretooidiosyncraticanduniquetosummarizetheircollective investmentskillaswecanforthemostactiveandpatientretailmutualfunds.

    At the same time, the outperformance we document is based on publicly availablequarterendportfolioholdingsthatanyonecaneasilyaccessontheSECwebsite.Thissuggeststhat other market participants may be either unaware of the persistent success of theseinstitutions, or, if they are aware, other market participants may underestimate theirinvestmentskill.

    Or,alternatively,evenifothermarketparticipantsseeandappreciatethetrackrecord,theymaysimplybediscouragedbecauseoftheirown lackofpatience.Asaresult,conditionssuchashavingastableinvestorbaseandarelativelackofpersistentcopycatsmayallowtheseinstitutionstobeuniqueandpatient(and,itturnsout,outperform).

    How patient does one need to be? In Panel A of Figure 4, plotting the cumulativeabnormaloutperformance forportfoliosofmutual funds shows that theportfolioofmutualfundswithhighActiveShareand longFundDurationoutperformedonlyslightly inthe first5

  • years(19951999),thensubstantialoutperformancewasachievedin2000,withagainlittlegainin the 8 year period of 20012008, after which again substantial outperformance followed.PanelCofFigure4showssimilarlythat forhedge fundsoneneededtobepatience fromthemiddleof2000 to theendof2008before thequarterendholdingsof thepatient andhighActive Sharehedge funds substantiallyoutperformed.PanelBof Figure4 for all institutionsindicates that the portfolio of high Active Share and long Fund Duration institutionsoutperformed quite consistently over time. However, thismasksmuch dispersion and timevariationwithintheportfolio,asshown inPanelDofFigure4,whichpresentsthecumulativeabnormalreturnsforsomeofthe largest institutionswith longFundDurationandhighActiveShare. These figures underscore that both fundmanagers and investors sometimes need towaitseveralyearsbeforegettingrewardedfortheirpatience.

    A good example of an institutionwith a very active and patient approach is Ruane,Cunniff&GoldfarbInc.,managerofe.g.theSequoiafundthattypicallyinvestsinahandfulofpublicly traded stocks. The large idiosyncratic element in their investment strategy couldillustratewellwhy trying toexplain theiroutperformance ishard ifnot impossible, i.e.,highActive Share, patient institutions may generally be very distinct from each other andidiosyncratictothemarket.Thisdoesnotmeanthatthereisnoparticularinvestmentstrategy.Forexampleforthe investmentstrategyoftheSequoiafund,apreferenceforstocksthatcanbe held for the longterm rather than for stocks whose performance may depend on thebusiness cycle (potentially warranting trading at business cycle turning points) seemsfoundational: We're really onebalancesheetata time, onecompanyatatime kind ofinvestors,Mr.Poppe [comanagerof theSequoia fund]said inMay2008at theshareholdermeeting.Wedon'tspendalotoftimeonmacro.Today,thefocusisstillonbalancesheets,but the Sequoia managers try to minimize the impact of economic ups and downs on theportfolio. There'saheavierburdenonacyclicalcompany to find itsway into theportfolio,saysMr.Goldfarb [comanager of the Sequoia fund], as quoted in theWall Street Journal(2010).
