Carrying on from yesterday’s post, here are a few more things to look at when evaluating mutual funds.
Management Expense Ratios
The management expense ratio, or MER, is probably one of the most important factors. The MER is essentially the total of all expenses which the fund manager deducts from the assets of the fund, expressed as a percentage. In the United States, MERs are commonly in the realm of 0.80 to 0.90 percent. Some are higher, and some lower. In Canada, it is still quite common to see MERs in excess of two percent. A lot of noise has been made about this, but not much has changed.
The MER is important because it is a drag on performance. Funds that charge high MERs have to perform that much better in order just to match the performance of the market. For example, if the S&P 500 index returns 10% in a given year, a fund with a 2% MER would have to beat the market by at least 2% in order to just match the index’s performance. Given that the majority of fund managers can’t consistently beat the market year after year, it becomes clear that funds with high MERs are handicapped right from the start.
So, in general, the lower the MER, the better. Index funds will always have the lowest MERs since they have very little overhead. You don’t need a high paid fund manager to run an index fund.
Comparing Performance
It’s tempting when looking at mutual funds to spend a lot of time looking at past performance, but as the fund literature always says, past performance is not a guarantee of future performance. Some funds have winning streaks for a period of many years, but then lose their touch, and never get it back. Still, it’s one of the only indicators you have to go by in terms of evaluating the competence of the management team.
When comparing funds, we generally use some sort of benchmark. Funds are typically compared against an index which most closely matches the types of stocks the fund holds. For example, a large cap, U.S. stock fund will typically be compared to the S&P 500 Index, since that index is a measure of 500 large U.S. companies. A fund that invests in smaller capitalization companies would likely be compared to the Russell 2000 Index, which measures small cap U.S. companies.
In addition to comparisons against these passive indexes, funds are often compared against a peer group of similar funds.
If you look up a fund on Morningstar.com, as we did in yesterday’s post, one of the first things you see on the page is a line chart like the one below.

This chart is for the Dodge & Cox Stock fund. The red line indicates the growth of $10,000 invested in the Dodge & Cox fund. The yellow represents the category average, and the green line represents the S&P 500 Index.
There’s a couple things to note here. Just looking at the lines on the chart can lead you to believe that this fund continually outperforms both the index, and the category average. However, look at the numbers below, and you’ll see that in 2007, and to date in 2008, the fund has underperformed both the index, and the category average. The exceptional outperformance that it had in 2004, and 2005 has skewed the funds performance line away from its two comparisons. But if Dodge & Cox Stock were to have a couple more years of underperformance, that line would come closer to the other two, and might even cross them.
Notice one other thing about these lines though. There’s a lot of similarities in the peaks and valleys. In other words, there’s a strong correlation between the market in general, and the portfolio that the managers at Dodge & Cox have selected. Notice also that there appears to be an even stronger correlation between the category average, and the index. This is why we say that in the long run, asset allocation is more important than individual security selection. Over time, the overperformances, and underperformances tend to cancel each other out, and you end up pretty much matching the index, minus the expenses you incurred along the way.
However, given the fact that you may only have certain funds to work with in your retirement account, this is at least one way you can gauge the past performance of the fund management. Looking at Dodge & Cox in my example, I’d feel comfortable having this fund in my portfolio. They at least have demonstrated the potential to outperform. Whether they will continue to do so in the future is a crap shoot. They also have an acceptably low MER of 0.52%, which is not bad for an actively managed fund.
Tomorrow, I’ll get back to the subject of asset allocation, and discuss some of the other asset categories, like international stocks, small-cap stocks, bonds, and real estate.
