64 II. Agency Problems of Financial Analysts (Sias, Financial Analysts’ Journal, 1996) Studies NYSE stocks (1977-91). Forms size deciles in each year. Within each size decile, he forms 3 equal-numbered groupings based on percentage institutionally held. Computes volatility using weekly data.

66 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.

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

68 Short-term Reversals Price pressure Reversals of over-reactions

69 Intermediate Momentum and Long-term Reversals Repetition of earnings surprises of the same sign (Bernard & Thomas). Over-estimating the length of the short- run.

74 Building Weak Expected Return Factor Models Brennan Chordia & Subrahmanyam

75 Methodology Study 970 NYSE stocks over the period 1977-89. Rank stocks first by size and form quintiles. Within each quintile, rank by book-to-price and form quintiles again to obtain a total of 25 groupings. Construct 5 stock portfolios, the returns to which account, as closely as possible, for the correlations among the returns to the 980 stocks. Use the portfolios as factors to explain the time-series of individual stock returns. Do the same with the size and B/P portfolio returns. In any given month, regress the cross-section of returns to the 25 portfolios on a profile of 13 portfolio characteristics. Do the same with the unexplained returns to the 25 portfolios. Compute means for the 13 regression coefficients (1977-89).

78 Response In the case of the 25 portfolios its, proportionately, like trying to estimate the payoffs to 2 factors with 4 plot points. In the case of the 25 portfolios, the exposures to all factors except size and B/P are likely to be quite homogeneous. The unexplained returns to the 25 portfolios are likely to be extremely small.
