Put-Call Parity and Expected Returns
This study examines the hypothesis that in the presence of market frictions, relative put and call prices contain information concerning future returns of the underlying asset. A measure of relative prices is derived from the put-call parity relationship for index options and applied to a three-year sample of OEX option transactions. The results show that the measure of relative index option prices leads the stock market by at least 15 minutes.
