We apply tags to Stocks and ETFs and Themes if they experience an unusual gain or loss. You can opt-in to receive email updates of unusual moves from your Watchlist in the notification centre.
How do we calculate an Unusual Gain or Loss?
Unusual Gain:
This label indicates that a stock experienced an unusual gain based on the closing price of the most recent trading day. The label is triggered by an approximate 2 standard deviation move from the average daily percentage change over the past 50 days.
This ensures the gain is specific to the performance of the particular instrument
Unusual Loss:
This label indicates that a stock experienced an unusual loss based on the closing price of the most recent trading day. It is triggered by an approximate 2 standard deviation move from the average daily percentage change over the past 50 days.
