Why it is important to tell if your mutual funds are 'closet indexers' and 3 ways to identify it

Pundits and casual observers will debate the pros and cons of mutual funds. Mutual funds are probably the most mainstream vehicle of active management, at least as far as retail investors are concerned. It is the appropriate strategy for critics of the efficient market theory, which is the idea that prices on assets, such as stocks and bonds, reflect all known information. The idea is to take advantage of mispricing in the market. As the strategy is in the hands of a money manager, volatility can be managed by investing in less-risky, high quality companies rather than in the market as a whole. It can also allow investors to take on additional risk to exceed higher-than-market returns. Furthermore, investments that are not highly correlated to the market help diversify a portfolio. This is the argument for active management, and this is where a problem arises.

Closet indexing is a when an active manager doesn't stray too far from the benchmark in their stock selections. They are "...pretending to be a stock-picking manager when you're [they're] really putting together a portfolio not much different from whatever index is the benchmark for your category of fund." (Stoffman 218) With a closet index fund, the MER is more than 2%, which is whopping considering that an index fund or exchange-traded fund charges significantly less.

Money managers are assessed by their ability to beat their relevant benchmark, which is the market index that best represents the portfolio they are managing. Trying to beat their index by a significant amount carries greater risk, so there are mutual fund managers that will fill their portfolio up with investments that make up their index, which means they'll never significantly underperform or overperform by a significant amount.

I'll try and update this blog entry with a more recent static but over 5 years ending June 2008, S&P 500 outperformed 68.6% of actively managed large cap funds, S&P MidCap 400 outperformed 75.9% of mid cap funds and S&P SmallCap 600 outperformed 77.8% of small cap funds. (Dash, Pane) The index has outperformed the majority of active managers. Therefore, following the index will mean outperforming a majority of their peers (also known as their competition), making it easier for the fund company to sell their funds. This does not provide value for the client and undermines a reason for pursuing an active management strategy in the first place, which is to do better than what the markets are doing. It's the reason a client pays a higher fee in the first place.

Following me? The investments and their allocation are incredibly similar between the fund manager 'actively-managing' and the benchmark he or she is being compared to. Therefore, if you're invested in a mutual fund that is a closet indexer, you will see far more value if you invest in an index fund or ETF that tracks these benchmarks themselves. With this, you are paying a significantly lower fee to get a similar result.

A mutual fund manager is guilty of being a closet indexer when (Stoffman 107):

1) It has a high R-squared (gives you a correlation between a fund and its benchmark index). The closer the R-squared is to 1, the more likely a closet indexed fund.

2) Check the annual report of an actively managed and its benchmark index fund. Check to see if similar stocks are held with similar proportions.

3) Compare recent returns of your actively managed fund and its benchmark. Do the returns of the managed fund regularly trail the index by its MER?
