In the past 20 years (since 2005 with the introduction of RegSho), short selling has come under scrutiny as millions of retail investors have discovered what we have been highlighting since early 2005. Market makers abuse the “market maker’s exemption” and short excessive amounts of shares in your stock without locating, borrowing, paying the rebate or the interest rate to borrow. They are required to cover on the same trading day, and our data proves they do not.

The chart below shows “Daily Short Volume” in Terns Pharmaceuticals, Inc. (TERN), and includes both EXEMPT (market makers) and NON-EXEMPT (everyone else) short sales. We consolidate the tape of all 14 US stock exchanges and purchase the “sell short” trade identifier data directly from the exchanges on a daily basis. This complete view of the trading in your stock shows a vastly different picture than “Total Short Interest”, which only includes non-exempt short sales that have not been covered by the twice per month reporting date. Unfortunately, this misses the majority of the short selling.

This indicates that a Short Squeeze may be starting in shares of Terns Pharmaceuticals, Inc. at $6.81, after crossing above the $6.635 Trigger Price. This could signal a buying opportunity, given the right market conditions.
