Beware of Skewed Performance Comparisons

Many people and fund companies still use inappropriate benchmarks for measuring investment performance. Instead of getting truthful results, investorsĀ are given a distorted perspective of performance which leads to mistaken conclusions.

The mutual fund industry’s (NasdaqGS:MORN) widespread use of peer group comparisons is a prime example of using erroneous yardsticks.

Back in 1991, William F. Sharpe warned about this in theĀ Financial Analysts’ Journal:

“Peer comparisons are dangerous. Because the capitalization-weighted average performance of active managers will be inferior to that of a passive alternative, the former constitutes a poor measure for decision-making purposes. And because most peer-group averages are not capitalization-weighted, they are subject to additional biases. Moreover, investing equal amounts with many managers is not a practical alternative. Nor, a fortiori, is investing with the “median” manager (whose identity is not even known in advance).”Ā Ā 

Based upon my own informal studies, there are four types of individuals (and institutions) that reject the robust performance comparisons of corresponding passive indices (NYSEARCA:SCHB) and here’s the reasons why:

ā€¢ Group A: They reject apples-to-apples comparisons because they want to cherry pick benchmarks that skew their performance in an unrealistic but favorable way.
ā€¢ Group B: They reject apples-to-apples comparisons of passive blended benchmarks because theyā€™re like the majority of the financial services industry; lazy.
ā€¢ Group C: They prefer to be secretive about their performance record before investing clients rather than be held accountable for results.
ā€¢ Group D: They donā€™t measure performance because they donā€™t know any better.

The flip side of people who want ignore or skew performance resultsĀ is the constituencyĀ that focuses exclusively on performance and nothing else. This is a short-sighted view, however, because it ignores important facts like: How much did risk (ChicagoOptions:^VIX) did the investor take to achieve a certain performance return? How much in fees and taxes did the performance cost?

My experience at analyzing and gradingĀ over $100 millionĀ dollarsĀ via the Portfolio Report CardĀ shows a common thread: If a personā€™s portfolio grades poorly in the first four categories (diversification, risk, cost, and taxes) itā€™s almost guaranteed they will score poorly on performance. Put another way, your portfolioā€™s performance (good or bad) is directly linked to how well you do at managing risk, diversifying, and minimizing cost along withĀ taxes.

But therein lies the problem for most investors: You can’t know what your portfolio’s true performance is if youĀ or your financial advisor (NasdaqGS:LPLA) areĀ using the wrong benchmarks.
