Please let me know if someone told me that your data is out of date ?
Yahoo finance used to be a good source -- notice I said used to be a good source -- which means they are not very good anymore. Why would I say this-- use your comment of 28.44 million shares short - that is totally wrong. The number they quote is from 11-15-17. To get latest numbers and they are about 2 weeks behind, but go to NASDAQ and you will find out the latest short interest and they update short interest in 2 week periods. Obviously there is a time delay to get the info, so currently last report is 2-28-18 and this coming Thursday they will update to 3-15-18. Below I have posted the link to Geron short interest on NASDAQ. Do yourself a big favor and question Yahoo Finance reports by using other sites.
