Role of Reputation For Mutual Fund Flows

Broad Question
1. Question:What causes investors to invest or withdraw money from mutual funds?
) In particular: what is the link between fund performance and fund flows?
2. Litarature:Narrow focus on ”Winner Chasing” phenomenon
) link between recent-most performance and fund flows ignoring role for reputation of fund
3. This paper: Role of Fund Reputation) Investor’s choices) Risk Choices by fund managers
Why Study Fund Flows?1. Important Vehicle of Investment
) Large: Manage 15 Tr $ (ICI, 2014)) Dominant way to equities: (ICI -2014, French (2008))
) HH through MF: owns 30% US equities) Direct holdings of HH: 20% of US equities
) Participation: 46% of US HH invest
2. Understand Behavioral Patterns:) Investors learn about managerial ability through returns) =⇒ fund flows shed light on learning, information processing
capacities etc.
3. Fund Flows Affect Managerial Risk Taking) Compensation ≈ flows: 90% MF managers paid as a % of
AUM)
)
=⇒ flow patterns can affect risk taking=⇒ impacts on asset prices
Literature Snapshot
1. Seminal Paper: Chevallier & Ellison (JPE, 1997)
Flows(t+1)
Returns(t)
=⇒ Convex Fund Flows in Recent Performance!
2. Why Interesting? Non-Linear Flows (could) mean
) Bad and extremely bad returns carry same information !) Non-Bayesian Learning) Behavioral Biases) Excess risk taking by managers given limited downside
Motivating Role of Reputation1. No Role For Reputation: Literature links time t returns (rit )
to time t + 1 fund flows (FF i , t+1)2. Why a Problem? The way investor perceives current
performance depends upon historic performance
Why? History of Returns ≈ reputation
Manager 1: {rt−3, rt−2, rt−1, rt} = {G, G, G, B}Manager 2: {rt−3, rt−2, rt−1, rt} = {B, B, B, B}
3. What it means for estimation?
FFi ,t+1 = g (rit, ri,t−1, ...) + errori,t+1
where g(.) is non-separable in returns4. Useful For Studying Investors Learning
FFi ,t+1 = g (

Data
1. Source: CRSP Survivor-Bias free mutual fund dataset 2. Time Period: 1980-2012.3. Include:
) Domestic, Open ended, equity funds) Growth, Income, Growth&Income, Small and Mid-Cap, Capital
Appreciation funds (Pastor, Stambaugh (2002))4. Exclude
) Sectoral, global and index or annuity funds) Funds with sales restrictions) young funds with less than 5 years) small funds (Assets < 10 Mn $)
5. Annual Frequency: Disclosures of yearly returns, ratings are based on annual performance
Performance Measures1. Reputation: Aggregate performance of 3 or 5 years prior to
current period2. How to Measure Performance?
) Factor Adjusted: CAPM α or 3-factor α (Fama,French (2010), Kosowski (2006))
) Peer Ranking (Within each investment style):(Chevallier,Ellison (1997), Spiegel (2012))
3. Which Measure?) Not easy for naive investor to exploit factors like value,
premium or momentum =⇒ factor-mimicking is valued (Berk, Binsbergen (2013))
) Flows more sensitive to raw returns (Clifford (2011))) Peer ranking within each style control for bulk of risk
differentials across funds) CAPM α wins the horse race amongst factor models
(Barberet.al 2014)
4.I use both the measures: CAPM α and Peer Ranking but not 3-factor model.
Main Variables
1. Fund Flows: Main dependent variable is % growth in Assets due to fund flows
FFi,t+1 =Ai,t+1 − (A it × (1 + ri,t+1))
Ait
A i t : Assets with fund i at time t rit : Fund returns for period ended t
Empirical Methodology

Implications
1. Shape:) Convex Fund Flows For Low Reputation) Linear Flows for Top Reputation
2. Level:) Flows% increasing in reputation for a given short-term rank
) Break Even Rank: 0.90 for Low reputation funds Vs 0.40 for Top repute funds
3. Slope:) Flow sensitivity is lower for low reputation, even at the extreme
high end of current performance.
Robustness Checks
1. Reputation: 3 or 5 or 7 years of history2. Performance Measure: CAPM or Peer Ranks3. Standard Errors:
) Clustered SE (cluster by fund) with time effects controlled using time dummies
) Cluster by fund-year (Veldkamp et.al (2014))
4. Institutional Vs Individual Investors5. Fixed Effects Model: To control for fund family effects

Section II:
Risk Shifting
Evidence on Risk Shifting: Background1. Do mid-year losing funds change portfolio risk?
) Convex flows =⇒ limited downside in payoff
2. Previous Papers:
) Brown, Harlow, Starks (1996): Mid-Year losing funds increase the portfolio volatility
) Chevallier, Ellison (1997): marginal mid-year winners benchmark but marginal losers ↑ σ
) Busse (2001):) Uses daily data =⇒ efficient estimates of σ) No support for ∆σ(r i t )
) Basak(2007):) What is risk? σ or deviation from
benchmark/peers?) Shows that mid-year losers deviate from
benchmark) Portfolio risk can be up or down (σ ↓ or ↑)
3. But Flows Are Not Convex For All Funds !
Measuring Risk Shifting1.Consider a simplest factor model
R i t = αi + mtβi
= s
lo¸a¸dx
ing
=sp¸r¸ic
xe
× R + s
t
2. Fact: Factors (e.g market) explain substantial σ(rit )
3. σ(rit ) Flawed meaure: Lot of exogenous variation for manager
4. Factor Loadings (β): Within manager control =⇒ good measure of risk-shifting
5. Measure of Devitation:
∆Risk = | βi,2ts¸¸xβ for 2nd half
− s¸¸xβ2t
median β for 2nd half
|
) Median β for funds with same investment style

Mean Estimates For Risk-Shift
Discussion of Results
1. Low Reputation Funds) Severe career concerns
) Low Mid-Year Rank: Gamble for resurrection
) High Mid-Year Rank: Exploit convexity of flows as risk of job-loss relatively low
2. Top Reputation Funds:) No immediate career concerns =⇒ Level of deviation slightly
higher
) Flows Linear =⇒ No response to mid-year rank
Section III
Model Of Fund Flows
Model Overview
1. Question: What explains the heterogeniety in observed Fund-Flow schedules
2. Possible Answer:) Investor-Base is heterogenous for funds with different
reputation or track record.
3. Basic Intuition:) A model with loss-averse investors + partial visibility
) Rational investors shift out of poor perfoming funds but loss-averse agents stick
)
)
=⇒ Bad fund performs poor again: No outflows
=⇒ Poor fund perform Good: Some inflows as fund becomes ’visible’
Model Outline
1. Basic Set-Up:) Finite horizon model with T < ∞) Two mutual funds indexed by i = 1, 2) Two types of investors (N of each type)
) Rational Investors (R): 1 unit at t = 0) Loss-Averse Investors (B): has η units at t = 0
22. At t = 0: Each fund has N of each type of investors3. Partial Visibility:
) Fund is visible to fund insiders at year end
) Fund visibility at t to outsiders increases with performance at time t
) visible =⇒ entire history is known
Returns and Beliefs1. Return Dynamics:
ri,t+1 = αi + εit+1
εit+1 ∼ N .0, (σε)2 .
where αi = unobserved ability of manager
i
2. Beliefs:) I i t = Set of investors to whom i is visible) For every j ∈ I i t , priors at end of t are
i tα ∼ N αit tˆ , (σ )2. .
) All investors are Bayesian =⇒ Normal Posteriors with
αit+1 αit i ,t +1 αitˆ = ˆ + (r − ˆ ) (σt )
2t ε(σ )2 + (σ )2
. .
Loss-Averse Investors1. Assumptions:
) Invest in only one of the visible funds at a time) Solves Two period problem every t as if model ends at t + 1
2. Preferences: Following Barberis, Xiong (2009)) πt = accumulated loss/gain for investor of B type with i) Instantaneous Utility realized only upon liquidation
u (πt ) =.δπ t 1 (πt < 0) + πt 1 (πt ≥ 0) If sell0 If no sell
) Evolution of πtπt+1 + ri,t+1πt +1 =
rj ,t +1 0
If no sellIf shift to fund j ∈ I i
If exit from industry
3. Trade-off: =⇒ B can mark-to-market loss today and exit fund i or carry forward losses in hope that rit+1 is large enough
4. Why? Loss hurts more: δ > 1
Motivation For Loss-Averse Investors
1. Strong Empirical Support:) Shefrin, Statman (1985), Odean(1998): Investors hold on
to losses for long but realize gains early) Calvet,Cambell, Sodini(2009): Slightly weaker but robust
tendency to hold on losing mutual funds) Heath (1999): Disposition effect present in ESOP’s
) Brown (2006), Frazzini (2006): Institutional traders exhibit tendency to hold losing investments
2. Why Realized Loss-Aversion?) Barberis, Xiong (2009): Realization Loss Averse preferences
can generate disposition effect
) Usual Prospect utility preferences over terminal gain/loss need not generate tendency to hold losses

Optimal Policy For Loss Averse Investor1. Result 1: Participation Premium
) t α1tFor any π , liquidation of current fund is optimal if ˆ < 0.
) In fact, break-even skill is positive. That is ifVkeep (α1,min(πt ), πt ) = Vexit (πt ), then α1,min(πt ) > 0, for anyπt
) Similarly, break-even level for manager 2 skill α2,min > 0. Else B will exit but not shift to fund 2
2. How to interpret ”LOW reputation then?) Relative: Low relative to Top, but still with positive expected
excess returns.
) Replacement Theory: Bad managers are replaced or bad funds merge with good funds. Hence expectation about ”fund returns” never go negative (e.g Lynch,Musto 2003)

3. Discussion:) Simplification: General time consistent policy under learning
is complicated
) Lynch&Musto (2003): Similar simplification assumption with exponential utility and one-period investors
) Alternative: Assume exponential utility and one-period agents, so that policy of old and new agent coincide given information

› Sequence of poor performce =⇒ Higher fraction of Loss-Averse Investors in Fund
Equilibrium Fund Flows
Figure: Fund Flow Schedules
Alternative Theories1. Lynch & Musto (JF,2003):
) Optimal replacement of manager by company below a cut-off performance=⇒ Magnitude of shortfall has no information content)
) =⇒ asset demand similar below cut-off2. Berk & Green (JPE,2004)
) Decreasing returns to scale) Quantities (size of fund) adjust so that expected excess returns
on all funds are equalized to zero) Return chasing, differential abilities and lack of persistence are
all consistent with each other3. Lynch & Musto For Current Evidence?
) P(firing) and hence convexity decreasing in reputation) Consistent with empirics? Some manager firing even for ’Top’
category) =⇒ Some insensitivity should have been observed if firing
mechanism was true
Conclusions
1. Lack of Flow Convexity for Reputed Funds (or for 40% of Industry money)
2.No Risk Shifting For Top funds in response to Mid-Year rank
3.Some 2 nd half risk-sfiting for bad repute funds
4.Fund Flow heterogeniety could be explained through presence of loss-averse investors
