What Is the Morningstar Rating for Stocks?
The Morningstar Rating assists investors in identifying stocks that are either undervalued or overvalued, allowing them to sift through market noise. The rating is based on three criteria: a stock’s market price, its fair value estimate—Morningstar’s assessment of its intrinsic worth—and its Uncertainty Rating, indicating the potential variability of that estimate. Stocks rated 4 or 5 stars are viewed as undervalued, while those rated 3 stars are fairly valued, and 1- or 2-star stocks are considered overvalued.
