Overview
The tendency of investors to forgo loss realization in favor of gain realization, also known as disposition effect, is found to be lower in a trading environment with salient information on current holdings. Using proprietary data from a fintech platform for social trading, we apply a differences-in-differences approach to analyze variation in trading behavior within and between portfolios as they become publicly visible. The disposition effect is present in our sample consistent with prior literature, but we show that it diminishes by about 35% when trades and holdings are unhidden. Our findings have important implications for fund management reporting practices, and are robust to survivorship bias, learning effects, level of assets under management and alternative explanations.
