The daily short reports you refer to is not real short position activity. I just found out the only reliable short data is the FINRA twice monthly report. The daily figures count all sales stabilizing the market by MMs. You can do a search and find out more. I tried to post a link but was blocked. The latest published short position for CTSO is only 2,000 shares.
Yes, it can be but the daily FINRA SHORT INTREST figures are also true, real and OFFICIAL. "MMs sales stabilizing the market" means in real, true language: "MMs pushing down every day, every hour the PPS of CTSO. " I don't see the same massive short-selling to even 70% of the total volume in other securities.
I'm now studying-preparing a complaint at the SEC but not for short-selling (it's legal) but for predatory short-selling. I've looked and found on internet very intresting lecture but i agree: it's a complex story... but i'm now retired and so i have the time and it keeps me busy... After some reading, i'm thinking that even the fact that the SEC starts an inquiery, can be enough to stop some malpractices...
Interested parties can access the reports to which you refer by searching "otc equity short interest". Such a small number explains why Yahoo! Finance shows the short statistics as "N/A" and answers the question as to who would short a twelve-cent stock (now) with miniscule trading volume, the answer to which is nobody in their right mind.
