Increased Short-Selling Flow
Cooper Companies (COO) has been flagged for unusual short-selling activity based on the latest FINRA Reg SHO daily short-sale volume files. For the trading day of October 28, 2026, the stock exhibited a 50.4% off-exchange short-volume ratio, which is a +1.9 standard deviation move from its 20-session average.
Analyzing the Data
This data represents the daily volume of trades executed as short sales. With 615,100 shares shorted off-exchange, the activity suggests a high level of bearish participation. While this is not a measure of total open short interest, the deviation from the 20-session average suggests that the intensity of short selling in COO has increased significantly. Investors should monitor this alongside official short interest updates to see if this flow is resulting in a build-up of long-term short positions.
