Self‐Selection and the Forecasting Abilities of Female Equity Analysts

Journal of Accounting Research 2010 48(2), 393-435
ABSTRACT This paper investigates whether there are systematic differences between the forecasting style and abilities of female and male analysts, and whether market participants recognize these differences. My key conjecture is that only female analysts with superior forecasting abilities enter the profession due to a perception of discrimination in the analyst labor market. Consistent with this conjecture, I find that female analysts issue bolder and more accurate forecasts and their accuracy is higher in market segments in which their concentration is lower. Further, the stock market participants are aware of the male–female skill differences. They respond more strongly to the forecast revisions by female analysts even though those analysts get less media coverage. The short‐term market reaction is incomplete, however, because it is followed by a strong post‐revision drift. The perception of abilities is similar in the analyst labor market, where female analysts are more likely to move up to high‐status brokerage firms, while their downward career mobility is lower. Collectively, these results indicate that female analysts have better‐than‐average skill due to self‐selection and market participants are at least partially able to recognize their superior abilities.

The Idiosyncratic Volatility Puzzle: Time Trend or Speculative Episodes?

Review of Financial Studies 2010 23(2), 863-899
[Campbell, Lettau, Malkiel, and Xu (2001) document a positive trend in idiosyncratic volatility during the 1962-1997 period. We show that by 2003 volatility falls back to pre-1990s levels. Furthermore, we show that the increase and subsequent reversal is concentrated among firms with low stock prices and high retail ownership. This evidence suggests that the increase in idiosyncratic volatility through the 1990s was not a time trend but, rather, an episodic phenomenon, at least partially associated with retail investors. Results from cross-sectional regressions, conditional trend estimation, stock-split events, and "attentiongrabbing" events are consistent with a retail trading effect.]
