I agree the current SHO list is pretty useless for traders. IMO they need to show us the totals for each stock on it. Perhaps they purposely don't to prevent traders from using the info.
The threshold to appear on the list is very low. Fails on a stock must be 10,000+ and equal to one-half of one percent or higher of the issuer’s total shares outstanding. Now, translate this over to a real-life stock like GLKCE. That company claims their o/s is around 2.0M. To get on the SHO list, it only needs 10,000 fails to deliver. We aren't shown whether their actual figure is that low or significantly higher. Can't really tell if SHO helped out, or it was something else.
