A Sharpe-ratio-based measure for currencies

Inference for the Sharpe Ratio Using a Likelihood-Based Approach

The Sharpe ratio is the prominent risk-adjusted performance measure used by practitioners. Statistical testing of this ratio using its asymptotic distribution has lagged behind its use. In this paper, highly accurate likelihood analysis is applied for inference on the Sharpe ratio. Both the oneand two-sample problems are considered. The methodology has O n−3/2 distributional accuracy and can be...

The Sharpe Ratio Efficient Frontier

We evaluate the probability that an estimated Sharpe ratio exceeds a given threshold in presence of non-Normal returns. We show that this new uncertainty-adjusted investment skill metric (called Probabilistic Sharpe ratio, or PSR) has a number of important applications: First, it allows us to establish the track record length needed for rejecting the hypothesis that a measured Sharpe ratio is b...

How to double a Sharpe ratio

Alternative investments have proved their worth. Witness the estimated $1 trillion under management in alternative assets, or the recent decision by major pension funds such as Calpers or British Telecomto to allocate up to 5% of their portfolio to alternative assets. And yet, standard risk-adjusted performance indicators often prove unsuitable for hedge funds, which rely on highly specific tec...
