I have been following the news relating to the Disney takeover of Pixar. You can check out a recent article about it at http://news.yahoo.com/s/ap/disney_pixar. Usually when this type of merger is announced, the acquiring company stock goes down, and the stock being acquired goes up. In this case, the reverse happened, at least at first. Disney went up and Pixar went down. However, the news on this had been rumored for a few months. Also, both Disney and Pixar have been moving up lately.
What I also read in another article was that Pixar CEO Steve Jobs (who is also the CEO of Apple Computer) will become the largest individual shareholder of Disney and will join Disney's Board of Directors. This should be interesting to watch in the next couple months. (In the interest of full disclosure, I own shares of Disney and Pixar. No purchase, sale, hold, or short recommendation is expressed or implied.)
