What are the meanings of metrics of benchmarks performance?

  • Can this PR answer your question?

Why is Sharpe Ratio not included in the metrics?

  • Sharp Ratio and Information ratio are both evaluation metrics which consider both return and risk.
  • Sharp Ratio is compared to risk-free return. Information ratio is compared to a specific benchmark. In our forecasting tasks, the model are predicting the excess return of stocks to CSI300 instead of risk-free return. So information ratio is a more reasonable metric.
