Hedging against embarrassment

This paper assesses the extent to which the expected disclosure to peers of an individual investor's financial performance influences his/her stock-trading decisions. In a lab experiment, participants trade in incentivized stock market simulations, knowing that their financial performance will be either made public or kept private. The results show a significant increase in the disposition effect when financial performance is to be made public, resulting from a spike in the realization of gains. We conclude by suggesting that this phenomenon may be due to individuals' strategic attempt to hedge against the embarrassment of ending the trading session at the bottom of the performance ranking.
