Debiasing Recency: Evidence from Individual Investor Stock Sales

In the first large-sample study of recency bias mitigation, we show that individual investors dispose of relatively longer-held stocks in December tax-loss sales compared to other months. We argue that before engaging in December tax-loss sales, investors review all or most of their losing positions instead of focusing on the most recently acquired stocks. Thus, reviewing relevant information mitigates recency bias in a large, diverse sample of investors. This behavior is consistent across investor, stock, and portfolio characteristics; it is found even in accounts with only long-term capital losses.
