IMO, HF-A sells to HF-B 500k shares knocking down the bid. It spooks retail. Retail sells. HF-B sells to HF-C 500k shares three days later, same thing. HF-C sells to HF-A two days later. They're a team so nobody ever reports they didn't receive the shares they "bought" and it never hits the FTD. The SEC isn't big enough to monitor this pro-actively. They only know about FTDs that are reported to them. I don't know any of this for sure, but that is what I think is going on. A bigger concern is a place like Goldman, being a broker and market maker, being in on it. The market makers are allowed to sell stock they don't have if there is a demand that needs to be met. That is meant to satisfy the ask being hit...but who's really watching? Nobody...except Cofer Black. It's just like there are way more robbers in the world than there are cops. The SEC can't monitor everything. They try, but they can't.
