Webb15 juni 2024 · Denote the mean of returns μ. Denote the standard deviation of returns: σ. Therefore the sharpe ratio is: S R = μ − r f σ. The corresponding standard errors are: s e ( μ ^) = σ t. s e ( σ ^) = 2 σ 2 T. s e ( S R ^) = 1 + S R 2 / 2 T. So the t-stat for the sharpe ratio is: WebbFund we use several tools. We calculated returns and risk-adjusted ratios: the Treynor’s ratio, the Sharpe’s ratio and the Jensen’s ratio. Because these ratios are less accurate in bearish markets, we calculated the normalized Sharpe ratio by doing linear regressions and we also calculated the modified Sharpe ratio.
