Ulcer Performance Index

Definition

Ulcer Performance Index是一種風險調整指標,評估相對於回撤深度和持續時間的報酬表現。與基於標準差的指標不同,它對持續性下跌施以更重的懲罰。

Formula

UPI=RpRfUlcer Index\text{UPI} = \frac{R_p - R_f}{\text{Ulcer Index}}

Where:

  • RpR_p = Portfolio return
  • RfR_f = Risk-free rate
  • Ulcer Index = Measure of the depth and duration of drawdowns
