Stockholders’ Unrealized Capital Gains Position and the Market Response to Earnings Announcements

Abstract: 
I examine whether stockholders’ average unrealized capital gains position in the equity of a given firm affects their response to the firm’s quarterly earnings announcements. Stockholders’ unrealized capital gains can affect their individual trading decisions via the capital gains tax “lock-in effect” or the tax-irrational bias known as the “disposition effect.” Prior literature is unclear about whether these two effects are significant determinants of the market reaction to earnings news. I design new tests that incorporate trade-by-trade data as well as quarterly institutional holdings data, and find robust evidence supporting the disposition effect. However, I also find that this announcement-window disposition effect is mitigated when tax incentives are stronger or more salient. Finally, I demonstrate that the disposition effect has important implications for measuring the degree to which the market incorporates earnings news. First, the disposition effect moderates the degree to which both opinion divergence and the differential precision of pre-announcement earnings information are reflected in abnormal trading volume. Second, the disposition effect diminishes the price adjustment to earnings news during the announcement window.
