In mid-2009, Morningstar introduced what it calls "moat trend ratings." Moat trend ratings can be either positive or negative. A positive moat trend indicates that a company's competitive position in strengthening. Conversely, a negative moat trend indicates that it is weakening. These moat trends have been an excellent indicator of stock performance.
