Abstract

Our study explores whether the disposition effect occurs in U.S. equity option markets. The disposition effect implies past winning securities will be undervalued and past losing securities will be overvalued. By adapting Grinblatt and Han’s [2005] unrealized capital gains proxy to the option markets, we document a significant relationship between option capital gains overhang (OCGO) and option returns. We also find open interest decreases as OCGO increases, consistent with a disposition effect in U.S. equity options. This evidence contributes to the emerging literature on behavioral finance in derivative securities.

Keywords: Disposition effect, options, behavioral finance, reference price.
