How Ratings & Stars Work

Morningstar RatingsTM Stars Rating

Reviewed monthly, this rating measures the extent and consistency of a fund's outperformance, relative to its sector, over a three-year period. Five stars is the highest rating.

Funds are ranked within their sector by dividing their average relative monthly performance over the last 36 months by their average monthly volatility.

The ranking the fund achieves in its sector determines how many Standard & Poor's Fund Stars are awarded:

No. of fund stars
Top 10% 5 Stars
Top 11-30% 4 Stars
Top 31-50% 3 Stars
Next 25% 2 Stars
Bottom 25% 1 Star
