Probabilistic sharpe ratio
Webb30 juli 2014 · The Sharpe ratio continues to be worth discussing precisely because it isn’t limited to the case of normal returns. Non-normal returns can produce inflationary effects on an unmodified Sharpe ratio. But the necessary modification is a straightforward one: redefine the SR in probabilistic terms. WebbWe 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 Sharpe ratio values for the set of three q-forwards with a 10-year maturity are reported in Table 7. WebbThis is because we can not have the same confidence in our SR^ estimations. With HF1 we have "only" a certainty of 92.99% that in the future its true SR will be greater than 0 (SR*), …

Next, we introduce the regime-switching model that we will use to turn the $\alpha$ and $\beta$ parameter of the CAPM model into time-varying probabilistic parameters. This model is similar to the one used in a previous post on the probabilistic Sharpe ratio.
