I think you are correct concerning the income tax cuts being extended again, that was pretty much decided by the election and short of a last ditch effort by the lame duck congress I think he will compromise with the Republicans.
But the capital gains tax is a different animal. Most agree that at least some increase in the capital gains will kick in on Jan 1st. This will be my last post on this matter, as we don't need to get in a political discussion regarding taxes.
My point is that a 67 year old director that is possibly on his way out has many reasons to sell stock at this time, and the tax provisions are just one of them. He still has 76,000 shares so it's not like he lost confidence in the company.
