Call-Option Pricing and the Turn of the Year

Article

Abstract

Historically, common stocks have had larger returns and variability of returns around the turn of the year and January. We find that call option prices reflect these historical patterns ex ante. That is, the higher return variability is anticipated and incorporated into the prices of call options whose trade date and expiration date fall on opposite sides of a turn-of-the-year period. These results suggest that both the turn of the year and the January phenomena are widely anticipated by financial markets before the fact.
