A time homogeneous, purely discontinuous, parsimonous Markov martingale model is proposed for the risk neutral dynamics of equity forward prices. Transition probabilities are in the variance gamma class with spot dependent parameters. Markov chain approximations give access to option prices. The...

We examine whether time-variation in the profitability of momentum strategies is related to variation in macroeconomic conditions. We find reliable evidence that the momentum strategy exposes investors to greater downside risk. Momentum strategies deliver economically large and statistically...

This paper develops a Monte-Carlo backtesting procedure for risk premia strategies and employs it to study Time-Series Momentum (TSM). Relying on time-series models, empirical residual distributions and copulas we overcome two key drawbacks of conventional backtesting procedures. We create...

Households face earnings risk which is non-normal and varies by age and over the income distribution. We show that allowing for these rich features of earnings dynamics, in the context of a structurally estimated life-cycle portfolio choice model, helps to rationalize the limited participation...

This article analyzes the effect of liquidity risk on the performance of various hedge fund portfolio strategies. Similarly to Avramov et al. (2007), we find that, before accounting for the effect of liquidity risk, hedge fund portfolios that incorporate predictability in managerial skills...

Data obtained from monthly Gallup/UBS surveys from 1998-2007 and from a special supplement to the Michigan Surveys of Consumer Attitudes, run in 22 monthly surveys between 2000-2005, are used to analyze stock market beliefs and portfolio choices of household investors. We show that the key...

We provide empirical evidence for the incomplete information model advanced by Merton (1987), which shows that the relation between idiosyncratic volatility (IV) and expected return is conditional on the firm's investor base. Using four different proxies for investor base, we show that...

This paper focuses on the horse race of weekly idiosyncratic momentum (IMOM) with respect to various idiosyncratic risk metrics. Using the A-share individual stocks in the Chinese market from January 1997 to December 2017, we first evaluate the performance of the weekly momentum and...

This paper demonstrates that risk-based and behavioral cross-sectional asset pricing anomalies can plausibly coexist. To this end, I build a model in which risk-based value premium exists along with behavioral momentum. The value premium stems from differential exposures of stocks to rare...

To explore how portfolio allocations among equities, fixed income securities, and cash are impacted by investors' risk and return expectations, this paper explores portfolio reallocations among equity, bond, and money market mutual funds. As predicted by the literature on optimal portfolio...
