The recent market volatility probably has you wondering how your strategy has fared through this unprecedented time. Disruptive market environments tend to reveal critical information about active managers that help investors see those that truly add value, and those that don’t. So, what should you do to evaluate your actively-managed strategy and how can you help your clients and prospects understand how your strategy performed during these difficult times? Read on.
Investment Performance in Up-Markets vs Down-Markets
During the long bull market run over the last 10+ years, investment firms have been able to effectively market their actively managed investment strategies with an emphasis on pure performance with little, if any, focus on risk. Consistent outperformance in up-markets is great, but it does not demonstrate how the strategy will react to a market downturn. Risk always goes hand-in-hand with performance and is increasingly important to discuss with clients and prospective clients as we navigate the highly volatile downturn we are currently experiencing.
Statistics used to present the results of actively managed strategies should do more than simply show the returns of the strategy vs. the returns of the benchmark. While returns show us where the strategy and benchmark ended and how much they changed over a stated period of time, they do not show how bumpy the road was to get there.
Investment performance and risk statistics should be used to help tell the story of how your firm actively manages the presented strategy. If your strategy description says that it will outperform in up-markets and provide protection on the downside, you should be presenting performance appraisal measures and risk statistics, such as Jensen’s Alpha, Sharpe ratio, Treynor ratio, up and down-market capture ratios, etc. that back-up those claims.
Types of Investment Risk
When assessing investment risk there are two main risk indicators to look at 1) systematic risk (i.e., market risk) and 2) total risk, which includes both systematic risk and unsystematic risk (i.e., security specific risk).
Systematic Risk Statistics
The most common way to assess the systematic risk of a strategy compared to its benchmark is by looking at the strategy’s beta. Beta measures the sensitivity of a strategy to market movements. If the strategy returns move perfectly in sync with the benchmark return then the strategy’s beta as compared to that benchmark is 1 (i.e., they are perfectly correlated).
If every time the benchmark goes up 1% the strategy goes up 1.2% and every time the benchmark goes down 1% the strategy goes down 1.2% then the beta is 1.2. This means that the portfolio has increased its systematic risk (perhaps through adding leverage, but otherwise replicated the index). In this case, the portfolio manager has increased the strategy’s systematic risk and volatility as compared to the benchmark, but the manager has not added alpha. This strategy will outperform on the upside and underperform on the downside.
To determine if the portfolio manager has “added alpha,” you can calculate Jensen’s alpha for the strategy. Jensen’s alpha measures how much the strategy outperformed its expected return, with the expected return determined based on the risk-free rate plus the beta-adjusted benchmark return. If the portfolio manager is truly “adding alpha” (through stock selection, over/underweighting sectors, etc.) and not just increasing systematic risk in their active management, then the strategy’s Jensen’s alpha should be positive.
Demonstrating positive alpha over a sustained period of time demonstrates to clients and prospects of the strategy that the active decisions made by the portfolio manager resulted in an increased return without increasing systematic risk.
Total Risk Statistics
Total risk is generally measured with standard deviation. Standard deviation has become more commonly presented, especially since the 3-year annualized ex-post standard deviation became required for GIPS Reports; however, this information may not be easily understood by readers of a performance report without some explanation.
If your investment strategy has returns that outperformed the benchmark AND has a standard deviation that is lower than the benchmark’s standard deviation, you can emphasize to your clients and prospects that you have outperformed the benchmark while taking less risk to do so (i.e., you had a less bumpy ride than the benchmark to get to your end result).
If your strategy’s returns did not outperform the benchmark, but your standard deviation is lower than that of the benchmark, you still may have outperformed the benchmark when looked at on a risk-adjusted basis. The most common way to assess this is with the Sharpe ratio.
The Sharpe ratio is one of the most popular performance appraisal measures. It measures excess return per unit of total risk. You can easily calculate this by taking your strategy’s average return minus the average risk-free rate and dividing that by the strategy’s standard deviation.
The Sharpe ratio is a ranking device, so the strategy’s Sharpe ratio on its own does not mean much. You should complete the same calculation for the benchmark and compare the two. If your strategy’s Sharpe ratio is higher than the Sharpe ratio of the benchmark then you can explain to your clients and prospects that you outperformed the benchmark on a risk-adjusted basis. For more information on how to calculate the Sharpe Ratio, see our latest blog What is the Sharpe Ratio.
In the volatile markets we are facing at the moment, outperforming the market (or your strategy’s benchmark) on a risk-adjusted basis may be more important than having outright higher returns. With the high volatility we are currently experiencing, returns could be changing significantly every day. The presentation of returns without consideration, discussion, and demonstration of risk only tells one part of the story.
By including risk as a second dimension of performance you will be able to exhibit skill over luck and demonstrate how your strategy is prepared to perform regardless of the market conditions we face over the coming months and years.
Tools to Calculate Risk Statistics
Depending on your strategy, there are a number of other statistics that can help you analyze how your investment performance has fared through the current market conditions. If you would like to calculate some of these measures on your own, please see Longs Peak’s Performance Appraisal Statistics Cheat Sheet for formulas.
In addition, Longs Peak calculates performance appraisal measures and risk statistics for our clients that can be used internally as part of your portfolio management feedback loop, and externally to help demonstrate the success of your active management to clients and prospects. Below are some samples of the reports we create. We would be happy to calculate or discuss any of these statistics with your firm.
If you have questions about investment performance and risk statistics, we would be love to help. Longs Peak’s professionals have extensive experience helping firms with their investment performance needs.
