I don't believe the MMs are playing games with this. It's usually not necessary with an OS this big. There are usually enuff swing traders and disgruntled longs to keep an adequate supply of shares in play. Add some of the large share holders throwing in a few here and there and more come in to play. Given what I have read in the Qs the market cap of the company is pretty close to right. A large block trading could cause blips in pps either way depending on buying or selling, but the key to a bigger market cap will be improving numbers on the Qs.
As an aside I do hope to see some pics of the convention also.
