Li: Have you any conjecture on this? 23 million unreported shares in one session? I'm sure there are many more in other sessions; I have not checked. Also, I see over 18,000 put contracts for Jan. and Feb. at $2.50. (1.8 million shares) That sticks out like a sore thumb. But I have not researched the innovative techniques of market manipulation that could be in play here.

<Market makers have been notorious abusers of naked shorting. In order to eliminate this abuse, "Regulation SHO" now requires them to itemize every trade. However, on August 27 when the rest of us watched 29 million shares of IMMU cross the ticker, only 6 million were reported. Nobody seems to have a plausible explanation.

I posed the question to another board, and the only response was that (1) maybe the trades didn't occur during "trading hours", or (2) maybe the trades were "odd lots", that is, transactions of less than 100 shares, or (3) maybe a couple of huge trades were routed through the market center, but the market center didn't have to report them to a consolidated tape.

The only possibility that makes sense is #3, but that would seem to be a blatant violation of Regulation SHO.
