INTRODUCTION
In our first paper Studying different Value Investing Strategies, we stated that when applying a bottom-upmechanical Value Investing system, you could beat the market over a number of years.
Still convinced and devoted value investors, or as Graham would put it;this involvesbuyingsecurities whose shares appear underpriced by some form(s) offundamental analysis, we wantedto go a step further and build a framework to construct and back-test a small size, mid- & small capinvestment fund.
For this study we changed the rules of the game to our own disadvantage and tried to get as close to the
real thing as possible. We did this by changing two capital items namely, by changing the benchmark and
by adding a minimum liquidity requirement on the purchased stocks, all the other most important
constituents are left untouched.
Benchmark:For this purpose, we constructed a new benchmark based on the weighted sum of the250 biggest tradedcompanies in the Euro zone (for this we excluded banks and insurance companies, because in our
screeners we exclude them as well).
As you will remember, in our first paper we used the EUROSTOXX as the benchmark including banks and
insurers, and we know what their performance was in the last few years.
To get the big picture of returns we also wanted our dividends reinvested, in both the Value portfolios and
the benchmark.
Minimum Liquidity:In our first paper, we worked with minimum market caps as an investment criteria. This is fine as long asyou can actually buy or sell stock without influencing its price in a mayor way.
For this study, we worked with a minimum liquidity threshold varying for the different portfolios, so that in
the end, the stock positions could be closed in 5 days.

SUMMARY
We will cover back-testing of portfolios of a size of 100.000, 500.000, 1.000.000 10.000.000 and20.000.000 over an 11-year period from 13/06/1999 up to 13/06/2010.The portfolios are formed by 9 value investing screeners (explained in the glossary part of this paper) and
tested against an index or market portfolio constructed specially for this study.We also wondered if there is a benefit of financial analysis (in contrast with the efficient market hypothe-
sis), concentrated in small-and medium-sized firms, companies with low shares turnover (volume), and
firms with no analysts followings. Because as a small- and medium-size investor, we have an edge against
big institutional organisations, we do not have large sums of money to invest.
Our portfolio characteristics are as follows
Portfolios of100.000, 500.000, 1.000.000 , 10.000.000 and 20.000.000. Portfolios of30 and 50 stocks. Positions must be purchased within a maximum of 1 week (5 working days). Companies with a minimum market cap of15.000.000 (of course, if we demand a higher
minimum trading volume, the market Cap will be higher also).
12 months buy and hold strategy.
Our market portfolio is a portfolio consisting of a weighted sum of the 250 most important stocks of the
total industrial market of companies in our databases (sorted descending by the trailing 30 days average
trading volume), with weights in the proportions of the trading volume of the individual stock. Each year, theportfolio is reweighted based on their trading volume (based on the previous 30 days before 13/06)
Unlike our first paper, we use this benchmark instead of the EUROSTOXX, because in our analysis we want
to take into account the reinvestment of dividends paid by companies in the index and our value investing
portfolios, assuming that dividends are re-invested to purchase additional units of an equity at the closing
price applicable on the ex-dividend date.
It is also important to note that the EUROSTOXX contains many banks and insurers . The latter are not
included in our screener portfolios (we are not able to analyse them with our computer models), so it is
better to use an alternative benchmark.
Anyway, we looked at how our market portfolio is correlated with the EUROSTOXX index. The results of the
exercise are shown in the table and chart below.

With a correlation value of 0,9736 to the EUROSTOXX this is very clear.
Over an 11-year period (from 13/06/1999 until 13/06/2010), our Market portfolio has a total return
(dividends included and reinvested) of 11,42% (or 0,99% a year) vs. -21,21% (or - 2,14 % a year) for the
EUROSTOXX.
Evaluating these numbers, the least you could say is that the last decade was certainly not good for stocks
in general and that you were better off investing in bonds.
The different strategies will be back-tested and compared to our market portfolio. Risks and returns will be
examined, and the following items will be studied.

Academic theory states that higher-risk investments should have higher return long-term. Or in other words:
the greater the risk, the greater the expected return. But is this really true?
In his book "The new finance2, Professor Robert Haugen claims that value stocks have higher returns thangrowth stocks and that they are less risky!
In his book Finding Alpha, Eric Falkenstein even states that low beta stocks have higher returns None-theless, today it is a dirty little secret, something all good quants know, but it is rarely addressed directly3In our previous paper Studying different Systematic Value Investing Strategies on the Euro zone
stockmarket4 we have already stated that, a value based stock selection achieves a greater return thanthe EUROSTOXX, but we have not really examined the risk of the value portfolios against a benchmark.
It is our intention to take a closer look at the risk of these value strategies.
But before we start the tests, we first have to consider one more thing. We will put a maximum clearing
time span on our portfolio formation, i.e. depending on the portfolio size and number of stocks in it, we will
give ourselves a maximum of 5 days to settle the stocks in the different portfolios.
We can achieve this by putting a threshold on the liquidity of a stock before portfolio formation as follows;

WHY WE ARE NO BETA AFFECTIONADOS
The CAPM formula was developed in 1970 by William Sharpe and John Lintner and is based on the modern
portfolio theory (MPT) by Markowitz.
The CAPM redefines risk in terms of a securitys beta (), which captures the non-diversifiable portion of
that stocks (portfolio) risk relative to the market as a whole.
This eventually leads to a very convenient interpretation: a stock with a beta of 1,20 has a level of syste-
matic risk that is 20% greater than the average for the entire market, while a stock with a beta of 0,70 is
30% less risky than the market. By definition the market always has a beta of 1.
But there is something that bothers us, if we examine the back tests in each value portfolio we do beat
the market consistently.
In contradiction to the theory of efficient markets, this can only be explained through a higher risk or beta of
the portfolio ?
In fact, each and every value portfolio has a beta between min.0,2707 and max. 0,5899 ?
Like Newtons law, oreven Archimedess law, you should be able to compute the outcome to a certain de-
gree of accuracy.
With the CAPM, this is not the case, and we wonder what is wrong with it. Is it the formula, or the concept of
an efficient market?
We suspect the latter.

CONCLUSION
Although back testing is a purely academic exercise you can try to simulate reality by taking in accountsome basic rules with regard to the following issues;
1. Survival Bias:Most studies dont include companies that went bankrupt or that were taken over by others. In our test,
these companies were not excluded.
2. Look ahead Bias:When you are using data for your stock ranking that was not available at the moment of portfolio formation,your results will suffer from look-ahead bias. This bias results upwards.
We worked with accounting data from the previous fiscal year and waited 6 months to form our portfolios
and actual trading.
Example:
Back-testing for 1999, we took the accounting data from the end of 1998 and formed the different portfo-
lios on 13/06/1999. This ensured that all accounting data was available upon portfolio formation.
We formed our portfolios and waited 6 months before actually buying them. Then we held them until
13/06/2000 before again rebalancing the complete portfolio.
We back-tested for the period : 13/06/1999 and 13/06/2010
3. Bid-Asked bounce:It is practically impossible to buy large positions in micro cap stocks (

By joining the two screener selections of MF and Piotroski F_Score, you can increase your performance
substantially.
Adding more stocks to your portfolio (30 stocks versus 50 stocks) does not improve the overall return: on
the contrary, you decrease it.
Nevertheless diversification is one of the cornerstones of safe investing, and it helps you to sleep well at
night.
We think that a portfolio of +/-30 value labelled stocks should perform well as a long term buy and hold
strategy.
By using one of the screeners you limit your underperformance to the market to 2 years (over an 11-year
period) on average. You must realise that the value strategies can underperform the market for a num-
ber of years (this was the case in the dotcom period).
As discussed in our first paper, by applying a mechanical value screener, you minimise the emotional im-
pact on your portfolio. As is often the case you are your own enemy with regards to investing.
You can use the screeners as a tool to invest in the top 30/50 companies that are selected for a given
period or you can use it as a stock picking tool if you are better skilled than the average investor.
All investing periods are 1year buy and hold, the screeners are rebalanced at the same time over and over
again.
We advise you not to use the screeners as a guidance for shorting stocks, even though this seems theoreti-
cally logical, because the factor time can seriously go against you.
A study made by James Montier1 in March 2006 showed that adding a factor quality (ROIC) to the Green-blatt formula (It has a Price element EY and a Quality element ROIC) did not increase return in a major way,
instead it reduced total return (on a 12 year basis) and added more volatility.
This is a similar result we got on our back testing results from the Magic Formula in comparison with allother screeners.

GLOSSARY
The 9 mechanical Value Investing techniques that were tested are explained in this chapter and [the codesbetween parenthesis are the short codes used in the graphs in the paper].
1) Magic Formula as described in The little book that beats the market by
Joel Greenblatt [MF]
The Magic Formula stock strategy, developed by Joel Greenblatt inThe Little Book That Beats the Market
earned nearly 31% ANNUAL returns over a 17 year period.
The formula start with the list of all the companies in a monetary zone (we have 4 zones available in our
screener databases, namely EURO, UK, USA and Japan). For example in the EURO zone we have +/- 2000
companies available in our list. The formula then applies a ranking to those companies, from 1 to 2000,
based on their Return Of Invested Capital (ROIC). The company with the highest ROIC gets ranking 1, thecompany with the lowest gets ranking 2000.
Next, the formula follows the same procedure, but this time the ranking is done usingEarning Yield(EY).The company with the highest yield is ranking 1, and the company with the lowest earning yield receives
ranking 2000.
Finally, the formula combines the rankings. The formula is looking for the companies that have the best
combination of both two factors. So a company that is ranked 232nd best in ROIC and 153rd highest in EY,
gets a better combined ranking than a company that is ranked 1st in ROIC but only 1150th best in
EY,because the first company has a better combined rank of 385 (232 + 153= 385) than the second
company has (1 + 1150= 1151)
2) ERP5 [ERP5]
Finding stocks with a considerable margin of safetyisnt a stand alone feature. When it comes down to
investing in a stock, the investment needs to have a considerable earning power as well. So we thought of a
screening method (similar to the Greenblatt's Magic Formula ) that would cover the issue of cheapness and
earning power as well. We noticed in our back-testing, that the ratio Price to Book of a business gives a
good indication for finding value stocks. Instead of the 2-parameter model used by Greenblatt (EY & ROIC)
we will apply 4 parameters, but we are searching for a combination of cheapness and earning power.
We selected the following 4 variables:
Earning Yield : (EBIT/Enterprise Value)How much is a business earning compared to the enterprise value (purchase price) of the company.
ROIC : Last 12 months (Return On Invested Capital)How much capital is needed to conduct its business (earnings factor). The ROIC measure gives a sense of
how well a company is using its money to generate returns
Price to Book Value: How much margin of safety is there on the purchased price factor compared to thecompany's book value? Considerable research documents the returns to a high book-to-market investment
strategy (e.g., Rosenberg, Reid-, and Lanstein 1984; Fama and French 1992; and Lakonishok, Shleifer, and
Vishny 1994 )
5 year trailing ROIC

This indicates the development of earnings over a 5-year trailing period. A company could have had an
exceptional good year (or last 12 months), but did the company also obtain good returns on its investments
over a longer period (i.e. over the last 5-year business cycle)?
The formula is calculated the same way as the Magic Formula, but here we are combining the 4 rankings,
so we are looking for the best combination of all 4 factors.
3) Piotroski 's F-score for low price to book companies [Piot]
In a research paper3, written in 2000, Joseph Piotroski an accounting professor, from the University of Chi-cago, developed and successfully tested a system where, with the use of a few simple accounting based
ratios, you can achieve substantial index beating investment performances. He wanted to see if he could
develop a system (using a simple 9-point scoring system) that could increase the returns of a strategy of
investing in low price to book value companies. Buying only those companies that scored highest (8 or 9)
on his 9-point scale, or F-Score as he called it, over the 20-year period from 1976 to 1996 led to an aver-
age outperformance over the market of 13.4% on USA stock exchanges.
How is the Piotroski or F-Score calculated?Profitability1. Return On Assets (ROA)Net income before extraordinary items for the year divided by total assets at the beginning of the year.
Score 1 if positive, 0 if negative
2. Cash Flow Return On Assets (CFROA)Net cash flow from operating activities (operating cash flow) divided by total assets at the beginning of the
year.
Score 1 if positive, 0 if negative
3. Change in return on assetsCompare this years return on assets (1) to last years return on assets.Score 1 if its higher, 0 if its lower
4. Quality of earnings (accrual)Compare Cash flow return on assets (2) to return on assets (1)
Score 1 if CFROA>ROA, 0 if CFROA

8. Change in gross marginCompare this years gross margin (gross profit divided by sales) to last years.
Score 1 if this years gross margin is higher, 0 if its lower
9. Change in asset turnoverCompare this years asset turnover (total sales divided by total assets at the beginning of the year) to last
years asset turnover ratio.Score 1 if this years asset turnover ratio is higher, 0 if its lower
EvaluationPiotroski or F-Score = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9
Good or high score = 8 or 9
Bad or low score = 0 or 1
We will backtest the F-score stand alone and in combination with other Value screeners (MF, ERP5 , Price
to Sales, Highest 5 year average Earning Yield). In our first paper we found out that the F-score may help
you to substantially increase your investment returns, irrespective of what investment strategy you may be
following.
4) ERP5 - highest F-score [ERP/Piot]
This is a combination of ERP5 and the F-score. We first take the best 20% ERP5 companies (instead of the
lowest Price to Book companies) and then we sort them in a descending order according to the F-score. The
best 30 or 50 companies are then selected.
5) Highest 5-year average Earning Yield - sorted by the highest F-score. [5YeY]
As value investors, we believe that buying bad companies at very low prices is also a perfectly viablestrategy, provided, of course, they dont go bankrupt. One needs to separate the winners from the losers. As
we saw in our First Paper, the F score is the perfect tool for that purpose. The standard Piotroski analysis
works with low price to book stocks, but we can also look for cheap stocks by looking at their earning
power. We herefore use the 5 year average earning yield and select the highest 20 % of our database and
sort them next according to the F-score.
6) Price -to -sales -highest F-score [PS/Piot]
The price-to-sales ratio is called; the king of the value factors by O'Shaughnessy4. A price-to-sales ratio(PSR) is similar to its price-to-earning ratio, but measures the price of the company against annual sales
instead of earning. We wanted to test this theory and combine PSR with the F-Score and the relative
strength.
7) Modified ERP5: (F-score between 7 and 9, and then sorted in ascending orderaccording to the ERP5 ranking) [ModERP]
With this screener, we first select all the companies with a F-score between 7 and 9. Next, we sort them in
ascending order according to their ERP5 ranking. We finally take the best 30 or 50 stocks.
8) Tiny Titans [TinyT]
The screen looks for companies with a market cap between 25 million and 250 million, a price to sales
of less than 1, and finally, ranks the top 25 based on the greatest relative strength over the past 52 weeks.

This creates a list of highly volatile and risky stocks according to O'Shaugnessy4. Since 1998 the screenhas produced in the USA cumulative results of over 2000%. However, since 2007, the screen has struggled
significantly along with the overall market.
9) Magic Formula - highest F-score [MF/Piot]
This screener sorts for the Magic Formula first and then selects the highest F-score.

INTRODUCTION
http://www.value-investing.eu/articles/Paper1005_MFIE.pdf
Value investing is an investmentparadigm that derives from the ideas on investment
and speculation thatBen Graham & David Dodd began teaching atColumbia Business School in 1928 and
subsequently developed in their 1934 textSecurity Analysis.
SUMMARY
The beta coefficient was born out oflinear regression analysis. It is linked to a regression analysis of the
returns of a portfolio (such as a stock index) (x-axis) in a specific period versus the returns of an individu-
al asset (y-axis) in a specific year.
An asset with a beta of 0 means that its price is not at all correlated with the market. A positive beta means
that the asset generally follows the market. A negative beta shows that the asset inversely follows themarket, the asset generally decreases in value if the market goes up and vice versa.
