Downgrades are rarer than upgrades and, in published research, more informative. Here is what the studies found, why negative calls carry more weight, and what to check when one hits a stock you own.

In the best-known study, the price fell on the news and kept falling for months. Kent Womack’s 1996 paper in the Journal of Finance examined new buy and sell recommendations from major US brokerage firms. The initial reaction was large but incomplete. After new sell recommendations, prices drifted a further 9.1% lower on average, and the drift lasted six months.
| After a new… | Average further drift | How long it lasted |
|---|---|---|
| Buy recommendation | +2.4% | Short-lived |
| Sell recommendation | −9.1% | About six months |
The study is decades old and markets now react faster, so treat it as evidence about the pattern, not a current estimate. Later work points the same way. In a 2001 Journal of Finance study by Barber, Lehavy, McNichols and Trueman, returns from slower trading strategies shrank, but remained significant for the least favorably rated stocks.
Mainly because they are scarce. In the latest 12 months of ratings from the 1,148 analysts in Exent’s ranking, Sell ratings were a small fraction of the total:
| Rating | Ratings, latest 12 months | Share |
|---|---|---|
| Buy | 129,728 | 70.7% |
| Hold | 48,405 | 26.4% |
| Sell | 5,259 | 2.9% |
An analyst who goes against that tide takes a visible career and relationship risk, which is one commonly cited reason negative calls are read as a genuine change in view. A move from Buy to Hold is often read the same way: a polite negative. More in why analysts rarely say sell.
A downgrade is any move to a less positive rating: Buy to Hold, Overweight to Equal-weight, Hold to Sell. A price-target cut with the rating unchanged is not a downgrade, though it can signal the same direction. Dropping coverage is different again, and often says little. The vocabulary is in analyst ratings and price target.
A minority. In a 2011 paper in the Review of Financial Studies, Loh and Stulz found only 12% of recommendation changes, up or down, visibly moved the stock price. The ones that did were more likely to:
It should be part of the read. In Exent’s 7-year backtest (statistics as of Nov 2, 2026), the average analyst’s price targets were reached 53.1% of the time, while 5-star analysts reached a median 59.8%. Hit rates across individual analysts ranged from under 30% to over 80%. Each analyst’s record is on the analyst rankings; see how to judge an analyst for what to look at.
Across 958,671 ratings, the average Wall Street analyst’s price target was reached 53.1% of the time: close to a coin flip. The spread between analysts is wide, and 14.9% of the 942 analysts with a measurable record reached 70% or more (Exent data, Nov 2, 2026).
Exent Gems is built on the top 50 of Exent’s ranking. Over the last two years, some of them reached 90% or more of their price targets. Who they are, which stocks they are calling now and how often they have been right is for members.
A downgrade is best read in the context of the whole portfolio: how large the position is and what else moves with it. For the opposite case, see analyst upgrades explained. This is general education, not advice on any security.
No. Most of the reaction tends to come on the day, and only a minority of rating changes visibly move prices. A 2011 study put the share of influential changes at 12%.
In a 1996 study of new sell recommendations, prices drifted lower for about six months, by 9.1% on average. Markets react faster today, so treat that as a historical pattern.
In Exent’s data, 2.9% of the latest 12 months of ratings from the analysts in its ranking were Sell. Commonly cited reasons include access to company management, banking relationships and career risk.
Often it is read that way. With about 71% of ratings at Buy, moving a stock to Hold usually signals reduced conviction.
That depends on your plan, the reason for the call and the analyst’s record. This page is general education and not a recommendation to buy or sell.
