Ulcer Performance Index

Definition

Ulcer Performance Index是一种风险调整指标,评估相对于回撤深度和持续时间的收益表现。与基于标准差的指标不同,它对持续性下跌施以更重的惩罚。

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
