摘要:We comprehensively evaluate and quantify the contribution of competing explanations for momentum.  We find that the well-known explanations of momentum such as 52-week high, earnings surprises and others explain 64% of momentum and there is a still significantly large portion (36%) of momentum left unexplained. Our findings are robust under market conditions with strong momentum performance, and among stocks with high limits to arbitrage. We further find that momentum crashes are primarily driven by return components and variables relating to prospect theory and mental accounting (PT/MA), and the strategies based on fundamental and residual momentum perform well during market rebounds.
