The stock market is characterized by extreme fluctuations, non-linearity, and shifts in internal and external environmental variables. Artificial intelligence (AI) techniques can detect such non-linearity, resulting in much-improved forecast results. This paper reviews 148 studies utilizing...

We analyze the worst currency carry loss episodes in recent decades, including causes, attribution by currency, timing, and the duration of carry drawdowns. To explore the determinants of the length of carry losses, a model of carry drawdown duration is estimated. We find evidence that drawdown...

We assess the benefits of using frequency-domain information for active portfolio management. To do so, we forecast the bond risk premium and equity risk premium using a methodology that isolates frequencies (of the predictors) with the highest predictive power. The resulting forecasts are more...

The Black-Litterman (BL) model has been proposed as an alternative to Markowitz's average-variance model for the structuring of financial asset portfolios, allowing the incorporation of perspectives of fundamental analysts and guaranteeing a high degree of diversification. This model is applied...

This paper considers the task of forming a portfolio of assets that outperforms a benchmark index, while imposing a constraint on the tracking error volatility. We examine three alternative formulations of active portfolio management. The first one is a typical set up in which the fund manager...

Mutual fund managers face increasing competition and have incentives to quickly reallocate their portfolios in order to achieve the best risk-adjusted return. However, portfolio allocation is costly, as trading, administrative, and information costs all lower returns after management fees....
