This paper develops a new framework and statistical tools to analyze stock returns using high-frequency data. We consider a continuous-time multifactor model via a continuous-time multivariate regression model incorporating realistic empirical features, such as persistent stochastic volatilities...

This paper documents that momentum profits in corporate bonds prevail during weakening aggregate credit conditions, and are driven by losers. Consistent with this, we find that a conditional default factor explains the cross-section returns of corporate bond portfolios sorted by past...

We propose an asset pricing model in a production economy where cash flows are determined by firms' dividend and investment decisions. Managers choose extensive and intensive margins in payout policy while facing non-convex costs as firm cash holdings grow. Differences in the timing of dividend...

Firms with higher (lower) vote values have significantly lower (higher) future returns. Constructing portfolios based on an option-based measure of the value of voting rights yields average return spreads of about 80 basis points per month, and the return differences persist up to ten months....

Recent studies find stock returns are negatively related to idiosyncratic volatility (IVOL). We find that aggregate variables known to explain stock market volatility affect the IVOL and portfolio returns sorted by IVOL. Macroeconomic volatilities, yield spreads, dividend yield, trading volume...
