You should always verify for yourself what is really happening with "insider sales". Many are automatic sales to cover RSU vesting taxes which are due immediately.
Paul Otellini donated the 150,000 shares and did not sell them. I think he did it just before year end because the tax laws that apply in two weeks are unknown. Today he can donate them and take credit for them.
Nothing stinks. It just takes a little effort to verify the facts.
