We analyze a novel alpha momentum strategy that invests in stocks based on three-factor alphas which we estimate using daily returns. The empirical analysis for the U.S. and for Europe shows that i) past alpha has power in predicting the cross-section of stock returns, ii) alpha momentum...

This paper examines to what extent the momentum spread ratio (MSR) can predict momentum profits. The momentum spread ratio as a potential proxy of investor underreaction can significantly predict the momentum, industry momentum, and residual momentum, especially after 1994, suggesting that...

There is limited evidence of intraday predictability both in the cross-section of US stock returns (see Heston et al., 2010) and in the time-series of the aggregate stock market (see Gao et al., 2015). I find that statistical time-series predictability does not imply economic profitability,...

We show that stock prices underreact when there is a political event, reflected in higher momentum returns. We conjecture that political news crowds out stock news cause investors to distract, trade more indexes and underreact to firm specific news. We analyze momentum returns following general...

We demonstrate the estimation biases that arise when stock returns from 12 month prior and 2 month prior are included within intermediate and recent past momentum profits. These biases lead to an overestimation of intermediate past momentum but an underestimation of recent past momentum in the...

In discussions and critiques on the validity of the Efficient Market Hypothesis, there are two important research focuses: statistical analyses showing that the basic assumption of statistical independence in price series is violated and empirical findings that show that significant market...

This paper seeks to uncover the drivers of the idiosyncratic momentum anomaly. We show that: (I) idiosyncratic momentum is a distinct phenomenon that exists next to conventional momentum and is not explained by it; (ii) idiosyncratic momentum is priced in the cross-section of stock returns after...

We build an equilibrium model to explain why stock return predictability concentrates in bad times. The key feature is that investors use different forecasting models, and hence assess uncertainty differently. As economic conditions deteriorate, uncertainty rises and investors' opinions...

The correlation of returns for various equity asset classes has been high. In addition, the range or "dispersion" of returns across asset classes - and across sectors within those asset classes - has been low. These factors have made it difficult for active managers to outperform. But dispersion...
