The following is my opinion. It is what I believe and if you disagree that's fine. No one should be making trading decisions based on things posted on a message board anyways - period.
We've been through this before on the TRADES report. That TRADES report is not necessarily a report of numbers of shares bought and sold. It is a report of TRADES at or closer to BID and ASK. There are ways of making a purchase of shares look like a sell - by MM selling someone shares at or closer to BID instead of ASK. This is easier when the gap between BID and ASK is really tight - it's harder to notice when the difference is fractions of a penny. Don't tell me it doesn't happen. I have made purchases of other stocks where I put in the order for blah number of shares at ASK and was sold them at BID on purpose by the market maker.
Market makers have their reasons for everything they do. I won't try to understand all their reasons. If they were complete angels there would be no need for regulation. FINRA is introducing new rules on 2/28/2011 connected with short selling - for a reason.
What that TRADES report actually shows is:
"Sell" = the TRADE was done CLOSER TO the bid than the ask.
"Buy" = the TRADE was done CLOSER TO the ask than the bid.
"?" = the TRADE was done exactly between the bid and the ask.
I know this is hard to comprehend because I was earlier very confused about this report. The way to understand it better is to understand that it is technically IMPOSSIBLE for there to be more shares sold than bought. Every time a share is sold someone has to buy them, even if it's just the market maker.
