RT Journal Article SR Electronic T1 Idiosyncratic Momentum: U.S. and International Evidence JF The Journal of Investing FD Institutional Investor Journals SP 64 OP 76 DO 10.3905/joi.2016.25.2.064 VO 25 IS 2 A1 Denis B. Chaves YR 2016 UL https://pm-research.com/content/25/2/64.abstract AB This article explores an alternative definition of momentum that is calculated using the idiosyncratic returns from market regressions. By removing the return component due to market beta exposure, this new definition of momentum reduces the volatility of momentum strategies and generates sizeable alphas, even after controlling for traditional momentum. The results are confirmed in a sample of 21 countries, in addition to U.S. data. Most interestingly, the findings also hold in Japan, where previous studies have failed to find any significant power for traditional momentum strategies.TOPICS: Analysis of individual factors/risk premia, developed
