"I think that is going to relieve a lot of the concerns of the stock. The stock has definitely been lagging moves the broader market has had.

"You haven't seen any insider sales out of the company, they have a massive cash position and now you got Steve Jobs sending a letter to the board outlining exactly what's wrong with him, what the course is and that it's very optimistic. So I think you might have a lot of the concern that's been in the stock get off of it, and if anything, you're going to see a short-covering reaction pretty early."

"It's very positive that he came out and said this. I think it does put to rest all the speculation on his health and I think people will now start to focus on the business.
