11. Part I: What Pays Off

12. Probability Distribution For Returns to a Portfolio Possible Rates of Returns Probability Expected Return Variance of Return

13. Risk Factor Models l The variance of stock returns can be split into two components: l Variance = systematic risk + diversifiable risk l Systematic risk is modeled using an APT-type risk-factor model l Measures extent to which stocks’ returns [jointly] move up and down over time l Estimated using time-series data l Diversifiable risk is reduced through optimal diversification

14. Expected Return Factor Models l Expected return factor models measure / predict the extent to which the stocks’ returns are different from each other within a given period of time.

15. Expected Return Factor Models l The factors in an expected return model represent the character of the companies. l They might include the history of their stock prices, its size, financial condition, cheapness or dearness of prices in the market, etc. –Unlike CAPM and APT, not only risk factors such as market beta or APT betas are included cross-section l Factor payoffs are estimated by relating individual stock returns to individual stock characteristics over the cross-section of a stock population (here the largest 3000 U.S. stocks).

16. Five Factor Families l Risk –Market and APT betas, TIE, debt ratio, etc., values and trends thereof l Liquidity –Market cap., price, trading volume, etc. l Price level –E/P, B/P, Sales/P, CF/P, Div/P l Profitability –Profit margin, ROE, ROA, earnings surprise, etc. l Price history (technical factors) –Excess return over past 1, 2, 3, 6, 12, 24, & 60 months

17. The Most Important Factors l The monthly slopes (payoffs) are averages over the period 1979 through mid 1986. l “T” statistics on the averages are computed, and the stocks are ranked by the absolute values of the “Ts”.

19. The Most Important Factors l Among the factors that are significant (i.e., that can be used to distinguish between which companies will have higher returns and which will have lower returns) are: –A number of liquidity factors –Various fundamental factors, indicating value with growth –Technical factors, indicating short-term reversals and intermediate term momentum Suggest that technical factors provide marginal value when used in conjunction with fundamental analysis –Notably, no CAPM or APT risk factors are included!

20. Projecting Expected Return l The components of expected return are obtained by multiplying the projected payoff to each factor (here the average of the past 12) by the stock’s current exposure to the factor. l Exposures are measured in standard deviations from the cross-sectional mean. l The individual components are then summed to obtain the aggregate expected return for the next period (here a month).

22. The Model’s Out-of-sample Predictive Power l The 3000 stocks are ranked by expected return and formed into deciles (decile 10 highest). l The performance of the deciles is observed in the next month. l The expected returns are re-estimated, and the deciles are re-ranked. l The process continues through 1993.

25. Extension of Study to Other Periods Nardin Baker l The same family of factors is used on a similar stock population. l Years before and after initial study period are examined to determine slopes and spreads between decile 1 and 10.

27. Decile Risk Characteristics l The characteristics reflect the character of the deciles over the period 1979-1993.

28. Fama-French Three- Factor Model l Monthly decile returns are regressed on monthly differences in the returns to the following: –S&P 500 and T bills –The 30% of stocks that are smallest and largest –The 30% of stocks with highest book-to-price and the lowest.

47. Possible Sources of Bias l Survival bias: –Excluding firms that go inactive during test period. l Look-ahead bias: –Using data that was unavailable when you trade. l Bid-asked bounce: –If this month’s close is a bid, there is 1 chance in 4 that next and last month’s close will be at an asked, showing reversals. l Data snooping: –Using the results of prior studies as a guide and then testing with their data. l Data mining: –Spinning the computer.

48. Using the Ad Hoc Expected Return Factor Model Internationally l The most important factors across the 5 largest stock markets (1985-93). l Simulating investment performance: –Within countries, constraints are those stated previously. –Positions in countries are in accord with relative total market capitalization.

Three main steps: –Use risk factor models to estimate variances and covariances –Use ad hoc expected return factor models to determine desired stock characteristics and estimate expected returns Cannot just screen sequentially (“going around the corner”) for stocks with the desired characteristicsCannot just screen sequentially (“going around the corner”) for stocks with the desired characteristics –Combine this information into optimal portfolios through Markowitz optimization
