Morningstars style boxes, which have historically evaluated whether a fund falls into value, growth and blend categories, are divided into nine squares that provide investors with a quick synopsis for how managers run an individual fund. The boxes vertical axis notes small-, mid- and large-cap styles and the horizontal axis notes value, blend and growth funds.
The company said in a statement that, although the appearance of the boxes wont change, the new methodology aims to offer a "more precise portrayal of a stocks style characteristics one that is more in line with the way portfolio managers look at stocks."
For instance, the original methodology evaluated the stocks in which funds invest based on two factors: price-to-earnings and price-to-book ratios. The new method uses 10 factors to decide a stocks style. Value stocks will be evaluated based on price-to-book, price-to-sales, price-to-cash flow, and dividend yield, the company said. Growth stocks, meanwhile, will be evaluated using long-term projected earnings growth, historical earnings growth, sales growth, cash flow growth and book value growth.
As a result, Morningstar said it will change the style classifications for a "modest number" of funds. For example, Morningstar will change the style designation of the Janus, Janus 20 and Janus Olympus funds from large blend to large growth. And the Putnam Small Value classification will change from small blend to small value.
