13. The Arbitrage Pricing Theory  Estimating the macro-economic betas.  No-arbitrage condition for asset pricing.  If risk-return relationship is non-linear, you can arbitrage.

14. What Pays Off

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

16. Risk Factor Models  The variance of stock returns can be split into two components:  Variance = systematic risk + diversifiable risk  Systematic risk is computed using the following spreadsheet.

17. Spreadsheet for Computing Systematic Risk Portfolio Beta (Inflation) (Oil Price) 1.00 1.00 Correlation Between Inflation and Oil Price Portfolio Beta (Inflation) (Oil Price) Correlation Between Inflation and Oil Price 1.00 1.00

18. Risk Factor Models  Factor betas are estimated by relating stock returns to (unexpected) percentage changes in the factor over a period where the stock’s character is similar to the present.

19. Relationship Between Return to General Electric and Changes in Interest Rates -25% -20% -15% -10% -5% 0% 5% 10% 15% 20% 25% Return to G.E. -10%-5%0%5%10% Percentage Change in Yield on Long-term Govt. Bond Line of Best Fit April, 1987

21. Risk Factor Models  Factor correlations can be estimated over a longer period because they are, presumably, more stable over time. This may increase the predictive accuracy of factor models relative to more naïve historical estimates.

22. Computing Portfolio Systematic Risk 1.00 Portfolio Beta * Portfolio Beta * 1.00 (Inflation) +Portfolio Beta * Portfolio Beta * Correlation Between (Inflation) (Oil Price) Inflation and Oil Price + 1.00 Portfolio Beta * Portfolio Beta * 1.00 (Oil Price) +Portfolio Beta * Portfolio Beta * Correlation Between (Inflation) (Oil Price) Inflation and Oil Price = Portfolio Systematic Risk

23. Risk Factor Models  If your factors have truly captured the structure behind the correlations between stock returns, then portfolio diversifiable risk can be estimated by summing the products of (a) the diversifiable risk of each stock and (b) the square of its portfolio weight.

24. DiversifiableRisk Decreases with the Number of Stocks in a Portfolio Diversifiable Risk Decreases with the Number of Stocks in a Portfolio 40 1 4 7 10 13 16 19 22 25 28 31 34 37.00.01.02.03.04.05.06.07.08.09.10 Diversifiable Risk Number of Stocks in Portfolio

25. Expected Return Factor Models  The factors in an expected return model represent the character of the companies. They might include the history of their stock prices, its size, financial condition, cheapness or dearness of prices in the market, etc.  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).

27. Five Factor Families  Risk  Liquidity  Price level  Growth potential  Price history

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

30. Projecting Expected Return  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. Exposures are measured in standard deviations from the cross-sectional mean.  The individual components are then summed to obtain the aggregate expected return for the next period (here a month)

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

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

57. Possible Sources of Bias Survival bias: excluding firms that go inactive during test period. Look-ahead bias: using data that was unavailable when you trade. 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. Data snooping: using the results of prior studies as a guide and then testing with their data. Data mining: spinning the computer.

120. What’s Behind the Negative Payoff to Risk?

121. I. Over-valued and Risky Growth Stocks Expensive growth stocks tend to produce low future returns They also tend to be more risky (Fama/French 1992 Table II.)

122. II. Agency Problems of Financial Analysts (cf., Sias, Financial Analysts’ Journal, 1996)

123. Thus, There May be Two Causes for the Inversion in the Relationship Between Risk and Expected Return The market’s tendency to over-price the more volatile, growth stocks. The attraction of institutional investors to the more newsworthy, volatile stocks.

124. What’s Behind the Technical Payoffs to Price History? Short-term reversals Intermediate momentum Long-term reversals
