Calmar Ratio


The Calmar ratio, originating from Mr. Terry W. Young in 1991 in the United States under the company "California Management Account Reports," is a valuable metric for investors in hedge funds and other investments, offering several key benefits.


In general, it provides a holistic evaluation of a fund's performance by considering both returns and risk. This helps investors understand how effectively a fund generates returns relative to the level of risk it assumes.



The Calmar ratio aids in risk management by incorporating the maximum drawdown, which measures the extent of loss from a peak to a trough. It is determined by dividing the average annual rate of return by the maximum drawdown over the preceding three years .This information is crucial for investors to assess the downside risk associated with a fund and manage risk within their investment portfolio.


Calmar Ratio = Average annual rate of return / maximum drowdown


Moreover, the Calmar ratio facilitates comparative analysis, allowing investors to compare the performance of different funds or investment strategies. A higher Calmar ratio typically indicates superior risk-adjusted returns compared to a lower ratio.


In terms of interpretation, a higher Calmar ratio is generally preferred as it signifies better risk-adjusted returns. A high ratio indicates that a fund has achieved higher returns relative to the level of risk taken, which is desirable for investors seeking optimal risk-return profiles.



The Calmar ratio is a fundamental tool utilized by both analysts and fund managers to gauge fund performance and compare it with peers boasting higher returns. Here's a breakdown of its significant advantages:

The Calmar ratio offers investors a clear understanding of the relationship between risk and returns within the fund, thereby guiding them in making cautious investment decisions. It serves as an indicator of price stability by highlighting fluctuations in prices over time, providing investors with a transparent view of the fund's stability. Moreover, the Calmar ratio acts as a performance evaluator, with a higher ratio indicating superior fund performance and a lower ratio suggesting underperformance and increased vulnerability to fluctuations. Additionally, fund managers benefit from the Calmar ratio as it helps them assess fund performance and identify funds with low Calmar ratios that require further monitoring. Lastly, investors can utilize the Calmar ratio as a guide when selecting investment strategies, as it takes into account drawdowns experienced over the past three years, providing a comprehensive view of fund performance.



The Calmar ratio, while useful in evaluating risk-adjusted returns, has several drawbacks that investors should be aware of:


The Calmar ratio focuses on maximum drawdown over the more pertinent standard deviation of the portfolio, potentially leading to decisions that inaccurately gauge the portfolio's risk. Its resemblance to the Sharpe ratio might dilute its distinctiveness as an assessment metric, constraining its capacity to offer unique insights. Additionally, the fixed three-year calculation period may not sufficiently capture short-term fluctuations or longer-term trends. Evaluating the performance of cyclical stocks over the preceding three years may not present their true potential due to their varied performance across different periods. Furthermore, being a purely mathematical tool, the Calmar ratio disregards sector-specific behaviors and trends, which could be pivotal for certain investments. Lastly, future projections or anticipated changes, such as new market dynamics or government policies, are not taken into account, constraining its predictive capability.




Suppose a fund was initiated three years ago with an initial investment of $20,000. Over the course of five years, it grew to a value of $50,000 but experienced a low point of $15,000 during periods of economic instability. The average annual return during this time was 20%. Now, we aim to compute the Calmar ratio.



Therefore, the risk-adjusted ratio stands at 0.29, aiding in the assessment of whether the fund is a viable investment option. Assuming the investor sets a minimum Calmar ratio criterion of 0.35, this ratio falls short of meeting the threshold for investment consideration.


Moreover, we can utilize it for comparison with another fund boasting a Calmar ratio of 0.32. Consequently, the latter presents a higher risk-adjusted return and would be the preferable choice over the fund with a Calmar ratio of only 0.29.



The Calmar ratio serves as a risk-adjusted metric for evaluating the performance of hedge funds or commodity trading funds and determining their investment suitability. By assessing return relative to risk, it offers a more comprehensive measure compared to solely examining risk in isolation. Nevertheless, relying solely on maximum drawdown as a risk indicator can be overly stringent, as it may not accurately reflect overall risk exposure. In such cases, employing standard deviation as a measure of risk would be more appropriate, as it mitigates the influence of outliers.
