What Is the Morningstar Rating for Stocks?
The Morningstar Rating can help investors identify stocks that are truly undervalued or overvalued, cutting through the market noise. The rating is determined by three factors: a stock’s price, its fair value estimate—Morningstar’s estimate of its intrinsic worth—and its Uncertainty Rating, which captures the range of potential outcomes for that estimate. Stocks rated 4 or 5 stars are considered undervalued, those rated 3 stars are fairly valued, and the ones rated 1 or 2 stars are considered overvalued.
