Duolingo Faces Allegations of Illicit Trading Amidst High Short Selling

The chart below shows ALL of the short selling each day in DUOLINGO, INC. (DUOL). We have consolidated the tape of ALL US stock exchanges and dark pools (this means we get the TRADE IDENTIFIER showing whether the trade was a buy, sell or sell short). The data below shows just the short sales each day in your stock. It includes both EXEMPT (market makers) and NON-EXEMPT (everyone else) short sales in DUOLINGO, INC.. An average of 41.03% of the daily trading in DUOL is short selling. This is abnormally high and implies there is illicit trading taking place in your stock. We run automated surveillance and reporting algorithms that report manipulative market making and short selling (to FINRA, SEC, Whistleblower's Office and Dept of Treasury FINCEN). We then issue FINRA COMPLIANT research to our large user base to counteract this activity that is driving DUOL lower unfairly.
