Although I doubt Pike is short. What you say is not true. One can hold a short and long position at the same time. It is called shorting against the box. For example if you got a borrow but did not think that you would be able to get the shares again and the price was increasing. You could go short and long which creates a neutral position, till the time you wanted to change that by closing the long position.
With some exceptions, EXACTLY!! I think he was buying on behalf of a client or group that had reason to cover up some prior misdeeds.
if Pike covered the 160 million share short that you claim it had with the buys shown in the SEC filings then it would show a net zero position for Pike, not the long 160 million shares that it is showing now...
