Berkshire Hathaway Joins S&P 500

The shares in Warren Buffett's company are finally part of a major stock index -- the S&P 500. After Buffett split the stock by one share for fifty, the "B" shares of Berkshire Hathaway (BRK-B) now trade at $68, making them a possible purchase for retail investors. Buffett recently bought Burlington Northern (BNI) which will disappear as a publicly traded stock when it becomes part of Berkshire in a few weeks.
