AN
Summary:
The ulcer index (UI) stands as a pivotal technical indicator developed by Peter Marin and Byron McCann in 1987. Serving as a measure of downside risk, this article provides an in-depth exploration of UI, its calculation, and practical applications in the finance industry.
In the realm of finance, the ulcer index (UI) emerges as a crucial tool for risk assessment. Originating in 1987 through the efforts of Peter Marin and Byron McCann, this technical indicator uniquely evaluates the depth and duration of price declines, with a distinct focus on downside risk rather than the overall volatility encountered in traditional measures like standard deviation.

Understanding ulcer index (UI)
Initially devised for analyzing mutual funds, the UI found its place in the financial landscape with the publication of Marin and McCann’s 1989 book, “The Investor’s Guide to Fidelity Funds.” Unlike conventional volatility indicators, the UI directs its attention exclusively to downside movements, acknowledging the psychological impact of price declines on investors. The name “ulcer index” reflects the stress and unease associated with downturns.
Calculating the ulcer index
The ulcer index’s computation involves a meticulous three-step process, emphasizing precision in evaluating downside risk. The first step entails determining the percentage drawdown, highlighting the difference between the closing price and the 14-period high close. This value is squared, averaged over the specified period, and finally subjected to the square root operation, resulting in the ulcer index. The flexibility to adjust the look-back period allows for customization, offering insights into short-term or long-term potential declines.
Ulcer index formula:
- Percentage drawdown = [(Close – 14-period high close)/14-period high close] x 100
- Squared average = (14-period sum of percentage drawdown squared)/14
- Ulcer index = square root of squared average
Using the ulcer index
The UI, recommended by Marin, finds application as a risk assessment tool in various financial contexts where standard deviation is typically employed. Beyond its theoretical underpinnings, the UI can be charted over time for technical analysis, providing a visual representation of potential risk zones. Investors leverage the ulcer index to compare drawdown risks across different investment options, enhancing their decision-making process.
Using the ulcer index in finance
The ulcer index finds its utility in the finance industry as a reliable risk assessment tool. Investors and traders can employ it to gauge potential drawdown risks, providing a more nuanced understanding than traditional volatility measures. By focusing solely on downside movements, the UI offers a realistic portrayal of the challenges faced by investors during market downturns, steering clear of the exaggerated assessments associated with overall volatility metrics.
