What Is the Appraisal Ratio?

An appraisal ratio is a ratio used to measure the quality of a fund manager's investment-picking ability.

The ratio shows how many units of active return the manager is producing per unit of risk. This is achieved by comparing the fund's alpha, the amount of excess return the manager has earned over the benchmark of the fund, to the portfolio's unsystematic risk or 澳洲幸运5开奖号码历史查询:residual standard deviation. 

Understanding the Appraisal Ratio

Managers of an 澳洲幸运5开奖号码历史查询:active investment fund are tasked with selecting a basket of investments capable of beating the returns of a relevant 澳洲幸运5开奖号码历史查询:benchmark or the overall market. While that sounds easy in practice, few regularly succeed in achieving this goal, 🐻espܫecially when taking the fees that they charge into consideration.

Fortunately, there are several ways for 澳洲幸运5开奖号码历史查询:investors to analyze how good a job fu🌜nd managers do. One method to determine their investment-picking ability i♐s to use the appraisal ratio.

The appraisal ratio measures the managers' performance by comparing the return of their stock picks to the specific risk of those selections. Alpha, the portion of the return that the active management is responsible for, is compared to 澳洲幸运5开奖号码历史查询:unsystematic risk: the portion of risk associated with the investments being made rather than with the entire 澳洲幸运5开奖号码历史查询:securities market in general.

The ratio is calculated as follows:

 $\begin{aligned} &\text{Appraisal Ratio} = \frac { \text{Alpha} }{ \text{Unsystematic Risk} } \\ &\textbf{where:} \\ &\text{Alpha} = \text{rate of return for a selection of stocks} \\ &\text{Unsystematic Risk} = \text{risk of the selection of stocks} \\ \end{aligned}$​Appraisal Ratio=Unsystematic RiskAlpha​where:Alpha=rate of return for&❀nbsp;a selection&🎃nbsp;of stocksUnsystematic Risk=risk♛ of the selection of st♏ocks​

The higher the ratio, the better the performance of the manager in question. Low appraisal ratios signal that a fund is poorly run, taking on a lot of risk to generate the returns it delivers. A high reading, on the other hand, is positive, implying that the manager is outperforming their passive portfolio benchmark without making investors sweat too much by exposing them to excessive risk or 澳洲幸运5开奖号码历史查询:volatiltiy.

Appraisal Ratio vs. the Sharpe Ratio

Like the appraisal ratio, the Sharpe ratio also functions as an indicator of 澳洲幸运5开奖号码历史查询:risk-adjusted returns. There are some notable disparities, though.

The Sharpe ratio works out the difference between the portfolio return and the 澳洲幸运5开奖号码历史查询:risk-free rate of return. The appraisal ratio, on the other hand, is concerned with measuring the risk-adjusted return in relation to a benchmark, such as the Standard & Poor's 500 Index (S&P 500), as opposed to a 澳洲幸运5开奖号码历史查询:risk-free asset that is gua🀅ranteed to generate investors money, such as a U.S. Treasury se🧸curity.

Both financial metrics can come in handy. One of the areas where the appraisal ratio perhaps has an edge is in its index comparison. 澳洲幸运5开奖号码历史查询:Index funds are typically the benchmark used in comparing investment performance and the market return is usually higher♛ than the risk-free return.

The appraisal ratio is also generally more useful for measuring the consistency of an investment's performance.

Limitations of the Appraisal Ratio

Ratios that measure risk-adjusted returns can be interpreted differently. Not everyone is the same and each investor will have varying 澳洲幸运5开奖号码历史查询:risk tolerance levels, depending on factors such as age, financial situation, income, and general personality.

Another point worth raising is the complications that can arise when comparing multiple funds against a benchmark. Each fund might have different securities, 澳洲幸运5开奖号码历史查询:asset allocations for each sector, and entry points in 🌟their investments, making such assessments dif🍃ficult to interpret.

As is the case with all financial ratios, it’s generally best to consult several of them♔ rather than relying on just one. The moꦜre information that is taken under consideration, the better chance investors have at making more comprehensive and informed decisions about where to allocate their money.
