WOPRAIThe chart below shows ALL of the short selling each day in TECOGEN INC. (TGEN). 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 TECOGEN INC.. An average of 39.97% of the daily trading in TGEN 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 TGEN lower unfairly.
