We argue that default option is important for equity valuation and construct a model that explicitly prices the option to default or abandon the firm. An investment strategy that buys stocks that are classified as undervalued by our model and shorts overvalued stocks generates an annual 4-factor...

We develop a methodology for bias-corrected return-premium estimation from cross-sectional regressions of individual stock returns on betas and firm characteristics. Over the period 1963-2014, there is some evidence of a negative premium on the size factor and positive beta premiums for the...

We built the largest dataset of high-frequency exchange rates so far. Our sample covers the spot prices and order flows of 19 currency pairs over the last 15 years measured on Reuters and EBS at the thirty-second frequency. We show that common, price-based factors describe exchange rate dynamics...

Current R&D expenditures forecast cash-based operating profitability up to three years in the future and sometimes as much as ten years, but do not forecast asset growth. High R&D firms have positive loadings on a cash-based operating profitability factor, and zero alphas. Capitalizing R&D to...

We show that much of the profitability in equity option return strategies, which try to capture option mispricing by taking exposure to underlying volatility, can be explained by an IPCA model. The alpha reduction, relative to competing static factor models, is between 50% and 75% depending on...

We compare the performance of time-series (TS) and cross-sectional (CS) strategies based on past returns. While CS strategies are zero-net investment long/short strategies, TS strategies take on a time-varying net-long investment in risky assets. For individual stocks, the difference between the...

Corporate bonds with large increases in implied volatility over the past month underperform those with large decreases in implied volatility by 0.6% per month. In contrast to An, Ang, Bali, and Cakici (2014) who show that implied volatility changes carry information about fundamental news, our...
