[Obviously rhetorical questions. Feel free to rhetorically answer.]
I never believe in MM manipulation. The person who placed the sell at .90 could have used an AON order. Even if not an AON order, I still don't believe what was claimed. >>
There seems to be this picture in people's minds that MM's are sitting around watching monitors. It's all computerized. That said, by law, MM's must execute a buy order at the lowest ask -- if an order come in at that price. >>
If 100 shares are for sale at .90 at the top of the ask and I put an order in to buy 100 shares at .90 -- the MM can't skip over it and execute other orders for other traders at higher ask prices -- until my order has been filled...unless, as said, my order is an AON. An AON order, depending on the size, can prevent NM's from filling my buy order. >>
If my order is NOT an AON -- and the MM skips my order to buy 100 @.90 -- and instead fills orders below me at higher ask prices -- well -- if a MM practices that behavior, he/she has some 'splaining to do. It's not worth the fine for a MM. Also >>
There really could be traders who were holding 5 or 6 shares post-split. I saw buys, pre-split, for very low amounts >> 200,000 / 250,000 shares, etc.
