Campbell, Serfaty-De Medeiros, and Viceira (2010) propose an optimized method to hedge currency risk in portfolios of international equities. In a demanding out-of-sample test, incorporating transaction and rebalancing costs, and margin requirements we find their method reduces risk in real...

We examine the time-series risk-return trade-off among equity factors. We obtain a positive trade-off for profitability and investment factors. Such relationship subsists conditional on the covariance with the market factor, which represents consistency with Merton's ICAPM. Critically, we obtain...

Inspired by Aumann and Serrano (2008) and Foster and Hart (2009), we propose risk-neutral options' implied measures of riskiness and investigate their significance in predicting the cross section of expected returns per unit of risk. The empirical analyses indicate a negative and significant...

In this paper, we intend to explain an empirical finding that distressed stocks delivered anomalously low returns (Campbell et. al. (2008)). We show that in a model where investors have heterogeneous preferences, the expected return of risky assets depends on idiosyncratic coskewness betas,...

I use option prices to infer real-time moments of stochastic discount factors (SDFs). The moments are estimated, from daily SP 500 index option data, in real time, without relying on past observations. These moments are forward-looking and significantly predict the market excess return. The...

In this paper, we develop lower bounds on the variance of the permanent component and the transitory component, and on the variance of the ratio of the permanent to the transitory components of SDFs. Exactly solved eigenfunction problems are then used to study the empirical attributes of asset...

The early work of Tobin (1958) showed that portfolio allocation decisions can be reduced to a two stage process: first decide the relative allocation of assets across the risky assets, and second decide how to divide total wealth between the risky assets and the safe asset. This so called...

This paper investigates whether multivariate crash risk is priced in the cross- section of expected stock returns. Motivated by a theoretical asset pricing model, we capture the multivariate crash risk of a stock by a combined measure based on its expected shortfall and its multivariate lower...

We test the relevance of technical and fundamental variables in forming currency portfolios. Carry, momentum and reversal all contribute to portfolio performance, whereas the real exchange rate and the current account do not. The resulting optimal portfolio outperforms the carry trade and other...

We introduce a new approach to measuring riskiness in the equity market. We propose option implied and physical measures of riskiness and investigate their performance in predicting future market returns. The predictive regressions indicate a positive and significant relation between...
