Analyst Rating

An analyst rating is a formal recommendation issued by a professional securities analyst at an investment bank, brokerage, or independent research firm regarding a specific stock. These ratings typically follow a scale such as Strong Buy / Buy / Hold / Sell / Strong Sell, though each firm uses its own terminology — what Goldman Sachs calls "Conviction Buy," Morgan Stanley might call "Overweight," and Barclays calls "Positive."

Analyst ratings are accompanied by price targets — the analyst's estimate of where the stock will trade in 12 months. For example, a "Buy" rating with a $200 price target on a stock currently trading at $150 implies a 33% expected upside. Ratings changes, especially upgrades or downgrades by prominent analysts, can move stock prices significantly in the short term — a major upgrade from a Goldman Sachs or JP Morgan analyst can push a stock up 3-5% in a single day.

However, the track record of analyst ratings is decidedly mixed. Research consistently shows that the "consensus" rating (average of all analysts covering a stock) has limited predictive value. Studies by Baruch Lev and others found that stocks rated "Buy" outperformed "Sell"-rated stocks by only a small margin, and that following analyst upgrades after they're published captures minimal excess return because the market prices in the information almost immediately.

The structural biases in analyst ratings are important to understand: approximately 55% of all ratings are "Buy," 38% are "Hold," and only 7% are "Sell." This buy-side skew exists because analysts' firms often have investment banking relationships with the companies they cover, creating conflicts of interest. An analyst who issues a "Sell" rating on a company may jeopardize their firm's lucrative underwriting or advisory business with that company. Independent research firms like Morningstar, Value Line, or CFRA tend to have less conflicted ratings.
