I'm not that familiar with current regs on buyouts, and I'll apologize for my ignorance. Besides, I thought you only had to begin reporting if you had over a 5% interest in the stock. Not sure if you could fool around with multiple trusts, parallel accounts, etc... to accumulate more (would need a lawyer to tell us that).
I just wanted to comment on the price action which I thought was unusual. Speculation, only, and really just talking off the top of my head.
And yes, to the poster above, this does seem to be coming to the end of its move.
