We run a series here at the Fool pointing out that a famous investor bought or sold a stock and then wondering whether you should follow suit, but the title of this one is rhetorical. I hope.
The fact that the head of the U.S. Supreme Court, Chief Justice John Roberts, sold his shares in Pfizer
I do wonder if people blindly follow the gurus though. How many people try to mimic Warren Buffett's moves at Berkshire Hathaway
The answer to whether you should buy or sell Pfizer depends on the needs for your portfolio and your view of Pfizer's chances to succeed.
The best thing going for Pfizer right now is its solid 4.1% dividend yield. But that level or better is available from other pharmaceutical companies: Eli Lilly
The integration of Wyeth is going well, and the added revenue will make the loss of Lipitor next year sting a little less. But the company needs to find a way to replace those lost sales and then some to grow. Replacing $12 billion is a difficult challenge.
So should you sell Pfizer? I can see how Pfizer could fit into some conservative portfolios, but many people would be better off with a midsized drugmaker that's growing -- think Gilead Sciences
If you need more alternatives to Pfizer, consider the biotechs that this billionaire likes.
