About Analyst Ratings
Analyst ratings represent professional recommendations - Buy, Hold, or Sell - issued for a specific stock. Each rating reflects the analyst’s view at the time of publication and is tracked to measure historical performance.
Ratings Count
The total number of analyst ratings (Buy, Hold, and Sell) issued for the stock. This includes all published recommendations, even those not used in performance calculations.
Performance Calculation
To ensure accuracy and prevent duplication, only certain ratings are included in performance metrics:
•
One rating per analyst per month: If an analyst publishes more than one rating in a month, only the first is counted.
•
Updated ratings end prior ones: If the analyst changes their stance during that month (for example, from Buy to Sell), performance tracking for the earlier rating stops immediately on the update date, and the new rating begins tracking from that point forward.
•
Hold ratings excluded: Hold recommendations are displayed on the chart but are not counted in performance or return calculations.
Example
If an analyst rates a stock Buy on April 1 and changes it to Sell on April 20, the Buy rating’s performance is measured from April 1 to April 20. From April 20 onward, only the Sell rating is tracked.
Success Rate
Indicates the percentage of performance-accounted ratings that generated a positive return during their active period. For example, if 6 out of 17 accounted ratings were profitable, the success rate is 35%.
Average Return
Represents the mean return per active rating - showing the average gain or loss an analyst’s recommendation produced while it was active.
