When a developed-market investor buys emerging-market stocks, this investor may be justified not to hedge currency risk. Our analysis indicates that completely unhedged portfolios often perform better than fully hedged portfolios and are not significantly inferior to optimally hedged portfolios....

Policymakers fear the potentially destabilizing impact of fickle global investors on emerging markets. Euro area investors are significant participants in emerging bond markets and exhibit volatile flows, but their fickleness does not result in indiscriminate periods of surge and flight....

We develop a model of international portfolio choice in complete and incomplete markets with stochastic covariance between financial asset returns and exchange rates. The optimal investment strategies are derived in closed form. We estimate the model parameters and illustrate the optimal...

We propose a simple and dynamic approach to hedge currency risk which can directly be applied by international investors in diverse asset classes. Other than current mean-variance approaches it is robust to overfitting and can thus better anticipate optimal currency hedging for global equity,...

Bitcoin is an unregulated digital currency originally introduced in 2008 without legal tender status. Based on a decentralized peer-to-peer network to confirm transactions and generate a limited amount of new bitcoins, it functions without the backing of a central bank or any other monitoring...

Using a parametric portfolio optimization approach, I show how international momentum strategies can be significantly improved by decomposing global momentum returns. The parametrization models the optimal portfolio weights as a function of the decomposed components and overweights equity...

This paper investigates mean reversion properties of real effective exchange rates (REERs) using a semi-parametric quantile autoregression approach. This method accounts for non-normality and captures asymmetric and dynamic adjustments towards the REER's long run equilibrium, conditional on the...

We derive the optimal currency portfolio of an equity investor with no forecasting ability. This can be estimated based on observable parameters, including equity and currency covariances and the proportion of the investor's wealth held in risky assets. The currency position depends on the...

Currency investors exhibit a tendency to cut risk by pairing both longs and shorts following losses and a weaker tendency to add risk following gains. By differentiating between position level, portfolio level and aggregate cross-portfolio losses in currency investments we demonstrate that this...

Often, investors fully hedge their portfolios for currency risk. This can lead to significant drag in performance for currencies with negative carry. However, not hedging the foreign currency exposure can lead to significant drawdowns, especially for conservative investments. In this paper, we...
