market makers have requirements by the sec. There only required to report there shorts. They short to keep control of the stock... market makers have to have shares to sell. since you dont buy from other holders you buy from the MM. And I sell to the MM. So a MM will bank up some shares knowing the stock will run. So Dr Kim reports some news. The price starts rising, The MM sells till they run out of shares, then they start selling naked shorts. These are none existant shares. They do this to beat the price down. So this last time it might have been 10 million. So then they beat the price down, and buy back those naked shorts, and make them good. and they also try to bank some shares. So if we run to 3 then the MM will beat it down for a week afterwards. recooping. But they make millions doing this.. and the sec allows them to do it.
They are not required to,but they should try and keep and orderly market,that is why they are allowed to naked short,also once options start trading on INO it will be easier to keep and orderly market in INO.
