We study the effect of innovations in liquidity on stock-return volatility under the return-decomposition framework. Using revisions to equity analyst consensus forecasts to measure cash-flow news directly, we contend that both cash-flow news and expected return news correlate with liquidity...

Since momentum arbitrage activity, buying winners and selling losers, effectively enlarges the return spread between these two groups, I find that the momentum spread (the difference of the formation-period recent 6-month returns between winners and losers) negatively predicts future momentum...

This paper proposes a time series decomposition of book-to-market ratio (BM) into a trend component and an innovation component (I_BM). Under the framework of stock valuation with growth options, we demonstrate that I_BM is negatively related to the change of growth options and therefore...

We generalize the Ferreira and Santa-Clara (2011) sum-of-the-parts method for forecasting stock market returns. Rather than summing the parts of stock returns, we suggest summing some of the frequency-decomposed parts. The proposed method signi cantly improves upon the original sum-of-the-parts...
