In this paper, we propose a stop-loss strategy to limit the downside risk of the well-known momentum strategy. At a stop-level of 10%, we find, with data from January 1926 to December 2013, that the maximum monthly losses of the equal- and value-weighted momentum strategies go down from -49.79%...

Motivated by standard portfolio theory, this paper incorporates ex-ante volatility estimates in the construction of winner-minus-loser stock momentum portfolio. I find that over the 1927-2015 period this leads to an increase in the Sharpe ratio from 0.34 to 1.14 and strongly reduced crash risk....

Momentum is one of the largest and most pervasive market anomalies. However, despite a high mean and Sharpe ratio, momentum suffers from large negative skewness that comes from momentum crash periods. These crashes occur in times of both market stress and market rebound and thus variables that...

A risk management strategy is proposed as being robust to the Global Financial Crisis (GFC) by selecting a Value-at-Risk (VaR) forecast that combines the forecasts of different VaR models. The robust forecast is based on the median of the point VaR forecasts of a set of conditional volatility...

This paper shows that when an investor optimally rebalances her portfolio, learning about the parameter of the return process still induces a large negative hedging demand even after observing 83 years of asset market data. An investor with a 5-year investment horizon decreases the percentage of...

This paper proposes a structural approach to long-horizon asset allocation. In particular, the investor draws inferences about asset returns from a vector autoregression (VAR) with economic restrictions on the intercept, slope, and covariance matrix implied by the long-run risk model of Bansal...

Existing studies of household stock trading using administrative data offer conflicting results: Discount brokerage accounts exhibit excessive trading, while retirement accounts show inactivity. This paper uses population-wide data from PSID and SCF to examine the overall extent of household...

This study examines historical data on S&P500 and EURO STOXX 50, VIX and VSTOXX, VIX and VSTOXX futures, to reveal linkages between these important series that can be used by equity investors to generate alpha and protect their investments during turbulent times. A comparative portfolio...

Should long-term investors account for time-variation in model parameters? We develop a time-varying Vector Autoregressive model that can handle time-variation in intercepts, slopes, volatility and correlation, the leverage effect in volatility and fat tails. Long-term investors should take...
