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 ULTRAGENYX PHARMACEUTICAL INC.. An average of 36.01% of the daily trading in RARE is short selling. This is abnormally high and implies there is illicit trading taking place in your stock.

We then issue FINRA COMPLIANT research to our large user base to counteract this activity that is driving RARE lower unfairly.
