Jackknifing Stock Return Predictions [PDF]
SSRN Electronic Journal, 2008 We show that the general bias reducing technique of jackknifing can be successfully applied to stock return predictability regressions.

What Is the Expected Return on a Stock? [PDF]
The Journal of Finance, 2016 ABSTRACTWe derive a formula for the expected return on a stock in terms of the risk‐neutral variance of the market and the stock's excess risk‐neutral variance relative to that of the average stock. These quantities can be computed from index and stock option prices; the formula has no free parameters.

Innovative Efficiency and Stock Returns [PDF]
SSRN Electronic Journal, 2012 We find that innovative efficiency (IE), patents or citations scaled by R&D, is a strong positive predictor of future returns after controlling for firm characteristics and risk. The IE-return relation is associated with the loading on a mispricing factor, and the high Sharpe ratio of the Efficient Minus Inefficient (EMI) portfolio suggests that ...
