Ulcer Index (UI)
Definition of 'Ulcer Index (UI)'
The UI is a more conservative measure of risk than the Sharpe ratio because it takes into account the frequency of negative returns. The Sharpe ratio only considers the magnitude of negative returns, not how often they occur. This means that the UI can be a more accurate measure of risk for portfolios that experience frequent negative returns.
The UI is also a more intuitive measure of risk than the Sharpe ratio. The Sharpe ratio is a mathematical formula that can be difficult to understand for investors who are not familiar with statistics. The UI, on the other hand, is a simple measure that can be easily understood by investors of all levels of experience.
Despite its advantages, the UI is not without its limitations. One limitation is that it is only based on daily returns. This means that it does not take into account the effects of compounding over time. Another limitation is that it is only a measure of downside risk. It does not take into account the potential for positive returns.
Overall, the UI is a useful measure of downside risk that can be used to compare different portfolios. However, it is important to be aware of its limitations before using it to make investment decisions.
