Very interesting. The difference in shares doesn't seem to be a time related reporting issue, so who knows what's right? If true, it shows a definite trend towards further concentration in AMD ownership.
Actually, the investment community is probably, like this board, divided into believers and heathens. So without direct evidence one way or another one would expect that the believers would continue to accumulate on these "buying opportunities" and the agnostics/atheists will dump based on other issues.
