RT Journal Article SR Electronic T1 Beware the Bounce: Tax Loss Harvesting During a Stock Market Crash JF The Journal of Beta Investment Strategies FD Institutional Investor Journals SP jbis.2022.1.007 DO 10.3905/jbis.2022.1.007 A1 Ben Davis A1 Tianchuan Li A1 Vassilii Nemtchinov YR 2022 UL https://pm-research.com/content/early/2022/04/15/jbis.2022.1.007.abstract AB We compare three different approaches to mitigating post-crash underperformance risk associated with tax loss harvesting strategies: a stock-bounds approach, a risk model approach, and an enhanced risk model approach, adding extra controls on factors associated with reversal risk. We analyze the reversal risk by conducting a comprehensive sweep, evaluating the performance of 60,000 realistically simulated accounts over the last twenty-five years, and quantifying the extent of pre-tax underperformance during the most stressful periods for index tracking.
