A broker's or brokerage firm's rating of a security. Such a security is expected to do marginally better than the market as a whole for the period of time it holds the "market outperform" rating. Some firms call the rating "accumulate," "moderate buy," or simply "outperform." Different firms have different rating systems, but "market outperform" is usually one rating above "market perform" or "neutral," and one rating below "buy." For example, if the market is expected to go down slightly, but a certain company's fundamentals are thought to be sound, a brokerage firm might change that company's rating from market perform to market outperform.
An analyst recommendation that a stock is expected to outperform the overall market.
