Realized idiosyncratic volatility and retail investors

Research output: Chapter in Book/Report/Conference proceedingConference contributionResearchpeer-review

Abstract

Extract: Recent research demonstrates a negative relation between idiosyncratic risk and future return for some stocks. We explain this market irregularity with a behavioral finance argument. We argue that high idiosyncratic volatility stocks present a preferred trading habitat for individual investors because of the lottery-type qualities of these stocks. Consequently, individuals overvalue these stocks, reducing future return levels. Our findings that the negative idiosyncratic volatility premium is concentrated in the portion of the market that is characterized by relatively high retail investor trading support our argument. Moreover, we find that the phenomenon is particularly strong for daily returns and realized volatility, the result, we contend, of the activities of individual day traders.
