Shares of Warren Buffett's Berkshire Hathaway ended almost 5 percent higher after their first full trading day on news the stock is going into the S&P 500 index.
Berkshire's Class B shares closed today at $71.25, a gain of 4.94 percent from yesterday's (January 26) 4p ET close of $68.
But that's still below the 14-month closing high of $72.72 last Thursday (January 21), the first day of trading after the 50-for-1 stock split approved by shareholders the day before was put into effect.
