Chuck Jaffe at Marketwatch says that when it comes to building a mutual fund portfolio, less is usually more. Jaffe's point is that owning more than ten or so funds is at best unnecessary, and at worst can turn your holdings into an overpriced index fund.
With actively managed mutual funds, more is not necessarily better. Studies show that owning four funds in the same asset category is virtually certain to create a 'closet index fund,' which means that the combined performance of the funds winds up doing no better than the index for that asset class
Plus, that index-or-worse overall performance comes at a much higher cost than simply owning a mutual-fund or exchange-traded fund tracking the index.
...Ultimately, an investor can build a winning portfolio with no more than six funds covering domestic and foreign markets, large- and small stocks, bonds and money-markets. Sector funds and other issues can be used to flesh out the holdings and tilt the assets to areas the investor prefers, without creating massive overlap with the core holdings.
A portfolio that's a little more complicated is fine, but going much further -- with closer to 20 funds than a half-dozen, and with too many decisions to make -- is almost sure to leave you with an unmanaged mess."
While it is true that the more funds you own, the closer your portfolio becomes an overpriced index fund, it is also true that 10 cheap good funds are better than five expensive mediocre funds. There is also the risk of over-relying on an expert manager by focusing too much on a few funds - something investors in Bill Miller's Legg Mason Value (LMVTX) are finding out right now. Moreover, it can be impossible to own just a few funds when you consider many investors own funds in several accounts - 401(k)s, IRAs, etc and collectively owning 20 funds is all but unavoidable.
The article also features this dubious advice from a Morningstar exec.:
'It's a good time to check up and see if your fund is performing worse than you would have expected in a tumultuous environment,' said Christine Benz, director of personal finance at investment researcher Morningstar Inc. 'If performance is worse than you expected, then maybe the fund is a bad match for your risk tolerance.'"
But wouldn't such behavior lead to buying high and selling low? Don't most people buy funds after they perform better than expected? In fact isn't that how funds get highly rated in the first place? Weren't all the Janus funds performing better than expected in the late 1990s? By this logic you would have sold them all after they fell harder than expected in 2000-2002, missing the better than expected returns from 2003-2007.
There is nothing wrong with a focused fund portfolio. Our MAXadvisor Powerfund Portfolios newsletter publishes seven model mutual fund portfolios, none of which have held more than ten funds and ETFs. That said, there are cases for smaller allocations to certain more targeted funds that could increase the number of portfolio holdings to more than that.
Can Too Many Funds Spoil a Good Portfolio?
