At the end of January 2021, a group of stocks listed on US stock exchanges experienced sudden surges in their stock prices, which - coupled with high short interest – led to brief short squeeze episodes. We argue that these short squeezes were the result of coordinated trading by retail...

We develop a conditional capital asset pricing model in continuous-time that allows for stochastic beta exposure. When beta co-moves with market variance and the stochastic discount factor (SDF), beta risk is priced, and the expected return on a stock deviates from the security market line. The...

A small but ambitious literature uses affine arbitrage-free models to estimate jointly U.S. Treasury term premiums and …

Spreads of agency mortgage-backed securities (MBS) vary significantly in the cross section and over time, but the sources of this variation are not well understood. We document that, in the cross section, MBS spreads adjusted for the prepayment option show a pronounced smile with respect to the...

We derive a model-free option-based formula to estimate the contribution of market frictions to expected returns (CFER) within an asset pricing setting. We estimate CFER for the U.S. optionable stocks. We document that CFER is sizable, it predicts stock returns and it subsumes the effect of...

We look at the theory of arbitrage with taxation under certainty. The tax scale in our model is not linear. Under the … premise that tax scale is convex, we analyze prices that do not exhibit arbitrage opportunities. It turns out that there are … two kinds of arbitrage: unbounded as well as bounded arbitrage. With bounded arbitrage, the gain from forming an arbitrage …

We use relative value to measure limits to arbitrage in fixed-income markets. Relative value captures apparent … deviations from no-arbitrage relationships. It is simple, intuitive and can be computed model-free for any bond. A pseudo … therefore a better proxy for limits to arbitrage. We construct relative value indices for the US, UK, Japan, Germany, Italy …
