Classifying Mutual Funds: Reading the Label
If someone asked you what vehicle you drive, you could give a general answer such as, "A car," a more specific answer such as, "A station wagon," or an even more exact answer such as, "A Ford Escort."
Likewise, there are lots of ways to describe a mutual fund. You could group them by how they're named--throwing all the funds with "aggressive" in their title together. The problem with this method is that fund names can sometimes be misleading. And not everyone agrees on what aggressive means.
In order to help you get a handle on the thousands of funds out there, Morningstar breaks down funds according to what they actually invest in. In fact, we have three ways of categorizing funds: by Morningstar rating groups, by category, and by style box.
Morningstar Rating Groups
Like the terms car and truck, Morningstar rating groups are general descriptions. Morningstar uses the four groups--U. S. stock, international stock, taxable bond, and tax-free (municipal) bond funds--as the basis for its ratings.
Comparing funds within a Morningstar rating group is like comparing a truck with all other trucks. You get a general idea of which ones have the most horsepower, for instance, but you can't make specific comparisons between, say, pick-ups.
Morningstar Categories
Our categories are based on what a fund has actually owned over the past three years. They're very specific. We have 30 stock categories, ranging from funds that buy mostly technology stocks to those that buy mostly Japanese stocks. We also have 28 bond categories.
Categories are great for helping you pick new funds, because you can see which funds in each category have performed the best. They're also useful for comparing the performances of the funds you already own with those of similar funds (such as when you give your plan its yearly review).
Morningstar Style Box
A fund's style box is based on the kind of stocks or bonds it owns right now. Think of it as being the latest model of your fund. There are nine style boxes for both stock and bond funds. You can use the style box to see what your fund has been buying and whether it has changed lately.
