A stock or fund can rank well based on the standard Sharpe ratio but low on enhanced tail-risk-based Sharpe ratios that account for non-normal returns, and vice versa. The authors quantify these economically meaningful ranking differences and show that skewness dominates other variables in explaining the ranking variations for the Conditional Value-at-Risk (CVaR)-based Sharpe ratio. Both skewness and serial correlation play important roles in the ranking variations for the maximum drawdown-based Sharpe ratio. TOPICS: Analysis of individual factors/risk premia, VAR and use of alternative risk measures of trading risk
