What Is Adjusted Market Risk-Adjusted Return?

Adjusted market risk-adjusted return is a metric used in portfolio performance measurement that refines the concept of risk-adjusted return by considering the prevailing market risk environment. It aims to provide a more nuanced evaluation of an investment's performance, acknowledging that a portfolio's returns, when adjusted for its inherent risk, should also be assessed relative to the broader market's risk levels. This metric falls under the broader category of portfolio theory, offering investors a deeper insight into how effectively a portfolio manager navigated market-wide risks to generate returns. Adjusted market risk-adjusted return provides a more comprehensive view than simply looking at raw returns, as it accounts for the degree of risk undertaken.

History and Origin

The evolution of metrics like adjusted market risk-adjusted return is rooted in the development of modern portfolio theory (MPT), pioneered by Harry Markowitz in the 1950s. Markowitz's work emphasized the importance of diversification and the relationship between risk and return in portfolio construction. ¹⁴, ¹⁵Subsequent advancements, such as the Capital Asset Pricing Model (CAPM), further formalized the understanding of systematic and unsystematic risk.

Over time, as financial markets grew more complex and interconnected, the need for more sophisticated performance measures became evident. Early risk-adjusted measures like the Sharpe Ratio and Treynor Ratio provided significant improvements, but they primarily focused on the portfolio's risk relative to its own returns or a specific benchmark. The concept of incorporating the market's overall risk environment into the adjustment process gained traction as analysts sought to differentiate between skillful management and returns simply attributable to a generally rising or falling market. The push for greater transparency and comparability in investment performance reporting, particularly through standards like the Global Investment Performance Standards (GIPS) established by the CFA Institute, has also driven the refinement of such metrics. ¹¹, ¹², ¹³The GIPS standards, updated in 2020, aim to provide a globally standardized framework for presenting investment performance, encouraging the use of robust and fair methodologies.

Key Takeaways

• Adjusted market risk-adjusted return provides a more refined view of investment performance by considering both portfolio-specific risk and the broader market's risk levels.
• It helps distinguish between returns generated by skillful management and those simply influenced by overall market conditions.
• The metric is particularly useful for comparing portfolios across different market cycles or periods of varying market volatility.
• It offers a deeper understanding of a portfolio's efficiency in generating returns for the level of risk assumed within the context of prevailing market risk.

Formula and Calculation

Calculating adjusted market risk-adjusted return typically involves modifying a standard risk-adjusted return metric, such as the Sharpe Ratio, to incorporate a measure of market risk. While there isn't one universally standardized formula, a conceptual approach might involve:

Where:

• Portfolio Return: The total return generated by the investment portfolio over a specific period.
• Risk-Free Rate: The return on a risk-free investment, such as a U.S. Treasury bill. This represents the return an investor could expect with virtually no risk.
• Portfolio Risk: A measure of the volatility or standard deviation of the portfolio's returns.
• Market Risk: A measure of the overall market's volatility during the same period, often represented by an index like the VIX (CBOE Volatility Index) or a broad market index's standard deviation.
  ⁸, ⁹* Average Market Risk: A historical average of the market's volatility, used as a baseline.

This adjustment factor, $\frac{\text{Market Risk}}{\text{Average Market Risk}}$, scales the traditional risk-adjusted return to account for whether the market risk at the time was higher or lower than its historical average.

Interpreting the Adjusted Market Risk-Adjusted Return

Interpreting the adjusted market risk-adjusted return involves comparing a portfolio's performance against a benchmark while simultaneously considering the prevailing market risk environment. A higher adjusted market risk-adjusted return suggests that the portfolio has generated superior returns for the level of risk taken, even after accounting for the overall market's volatility. For instance, if a portfolio exhibits a strong risk-adjusted return during a period of unusually high market volatility, its adjusted market risk-adjusted return would highlight this outperformance more clearly than a traditional measure. Conversely, a seemingly good risk-adjusted return in a period of exceptionally low market risk might be tempered by this adjusted metric, indicating that the portfolio's success was partly due to favorable market conditions rather than solely superior asset allocation or security selection. This metric helps investors and analysts to differentiate true investment skill from market beta.

Hypothetical Example

Consider two hypothetical portfolios, Portfolio A and Portfolio B, both with an annual return of 10% and a standard deviation of 15%. Assume the risk-free rate is 2%. The market's average VIX over a long period has been 20.

Scenario 1: Normal Market Volatility (VIX = 20)

• Portfolio A (Sharpe Ratio): ((10% - 2%) / 15% = 0.53)
• Portfolio A (Adjusted Market Risk-Adjusted Return): (0.53 \times (20/20) = 0.53)

Scenario 2: High Market Volatility (VIX = 30)

• Portfolio B (Sharpe Ratio): ((10% - 2%) / 15% = 0.53) (same as Portfolio A)
• Portfolio B (Adjusted Market Risk-Adjusted Return): (0.53 \times (30/20) = 0.795)

In this example, while both portfolios have the same traditional Sharpe Ratio, Portfolio B's adjusted market risk-adjusted return is higher. This indicates that Portfolio B achieved the same risk-adjusted return during a period of greater market stress, suggesting more effective management in a challenging environment. This provides valuable context beyond simple performance measurement.

Practical Applications

Adjusted market risk-adjusted return is a valuable tool for institutional investors, fund managers, and financial analysts in several key areas. It is particularly useful in manager selection, allowing allocators to evaluate how well a fund manager performs relative to peers, especially during different market cycles. For instance, a manager who maintains a high adjusted market risk-adjusted return during periods of elevated market volatility, as measured by indices like the St. Louis Fed Financial Stress Index, demonstrates resilience and potential skill in navigating challenging conditions.

This metric also plays a role in performance attribution, helping to dissect whether a portfolio's returns are primarily due to the manager's unique investment decisions or simply a reflection of broad market movements. Furthermore, it aids in risk management by highlighting portfolios that may be taking on excessive risk relative to the market environment, even if their traditional risk-adjusted returns appear favorable. The Federal Reserve System, through its various branches, provides extensive data and analysis on market conditions that can inform the application of such metrics in real-world scenarios.

Limitations and Criticisms

While adjusted market risk-adjusted return offers a more nuanced view of portfolio performance, it is not without its limitations. One significant critique is the subjectivity in defining and measuring "market risk" and "average market risk." Different proxies for market volatility (e.g., VIX, historical standard deviation of a broad index, or the St. Louis Fed Financial Stress Index) can lead to different results. ¹, ², ³This lack of a universally agreed-upon standard can make comparisons challenging.

Another limitation is that the metric, like many quantitative measures, relies on historical data, which may not always be indicative of future market behavior. It also assumes that market risk can be adequately captured by a single factor, overlooking the complex interplay of various macroeconomic factors and their impact on different asset classes. Additionally, over-reliance on any single metric, including adjusted market risk-adjusted return, can lead to a narrow focus, potentially obscuring other important aspects of investment performance, such as liquidity or specific client objectives. Users must understand the underlying assumptions and potential biases when applying this metric, recognizing that it is one tool among many in a comprehensive financial analysis.

Adjusted Market Risk-Adjusted Return vs. Risk-Adjusted Return

The primary distinction between adjusted market risk-adjusted return and a standard risk-adjusted return lies in the context provided by market-wide risk. A traditional risk-adjusted return, such as the Sharpe Ratio, evaluates a portfolio's excess return (return above the risk-free rate) in relation to its total volatility or standard deviation. It answers the question: how much return did I get for the amount of risk I took?

Adjusted market risk-adjusted return takes this a step further. It asks: how much return did I get for the amount of risk I took, considering how risky the overall market was at that time? This additional layer of analysis helps to normalize performance across different market environments. For example, a portfolio might have an excellent Sharpe Ratio during a period of exceptionally calm markets. While good, the adjusted market risk-adjusted return would temper that result if the overall market risk was significantly lower than its historical average, providing a more realistic assessment of the manager's skill versus simply benefiting from a low-volatility environment. Conversely, a portfolio performing well in a high-beta environment would see its performance highlighted by the adjusted metric.

FAQs
