IMO, there are a couple of things going on, and they differ from your opinion.
First, notice how we virtually NEVER go below 80 cents? And when we do, there is a quick reversal back up to at least 80 cents? I`ve said it before and I`ll say it again: PTSC is in buy-back mode with a Good Till Cancelled huge limit order to buy at 80 cents. It`s our current ``stablizer``. Snagging a little at a time....
Second, and along these same lines, why would they sit on cash? For 4% interest? If they have no worries and have expectations of more deals over time, wouldn`t buying back stock be a much better investment?
Third, still along these lines: Stock = Cash. So in terms of being prepared for a buy out of some other entity, the stock (bought back) can be used just like cash to support the acquisition.
Who`s selling? I haven`t a clue. Could just be some people taking a little off this table to put on another one that they think is another up-n-comer. Diversification. But I believe any selling just plays into PTSC`s hands, which are just waiting to grab them. Notice the volume isn`t that great, so there is no big worry one way or the other.
All JMHO, and I KNOW nuttin`!
