Oil is perceived as a good diversification tool for stock markets. To fully understand this potential, we propose a new empirical methodology that combines generalized autoregressive score copula functions with high frequency data and allows us to capture and forecast the conditional...

This study conducts out-of-sample tests for returns on individual currency investment strategies and the weights on the universe of these strategies. We focus upon five investment strategies: carry, momentum, value, dollar carry, and conditional FX correlation risk. The performances of our...

This paper develops a dynamic portfolio selection model incorporating economic uncertainty for business cycles. It is assumed that the financial market at each point in time is defined by a hidden Markov model, which is characterized by the overall equity market returns and volatility. The risk...

DeMiguel, Garlappi, and Uppal (Review of Financial Studies, 22 (2009), 1915-1953) showed that in the stock market, it is difficult for an optimized portfolio constructed using mean-variance analysis to outperform a simple equally-weighted portfolio because of estimation error. In this paper, we...

We first develop a theory-based metric to judge the popularity of value-weighting in a stock market. We then use our metric to document that although value-weighting is less popular in emerging markets than in developed markets, its popularity is increasing almost everywhere. Finally, as we have...

This paper provides a new method to disentangle the systematic component from the idiosyncratic part of the risk associated with trend following strategies. A simple statistical approach, combined with standard dimension reduction techniques, enables us to extract the common trending part in any...

The way central banks manage their foreign reserve assets has evolved over the past decades. One major trend is managing reserves in two or more tranches-liquidity tranche and investment tranche-especially for those with adequate reserves. Incorporating reserve tranching, we have developed in...

We present effective momentum strategies over the liquid equity futures market in India. We evaluate and determine the persistence of the returns at various look-backs ranging from quarterly and weekly to more granular look-backs. We look at a universe of the liquid equity instruments traded...

Time series momentum (TSM) refers to the predictability of the past 12-month return on the next one-month return and is the focus of several recent influential studies. This paper shows that asset-by-asset time series regressions reveal little evidence of TSM, both in- and out-of-sample. While...

We introduce a covariance and spread (i.e., exchange rate forward discount) adjusted carry factor that prices the cross-section of FX market returns, where many other single and multi-factor models fail. Both the covariance matrix of exchange rate growths and forward discounts contain important...
