While I promise not to get into the business of writing about the daily ups and downs of Berkshire Hathaway's stock, I do think it's worth briefly noting that shares of Warren Buffett's holding company had a great day, in stark contrast to Wall Street's great gloom.
Berkshire gained 3.8 percent to close at $131,200 today (Thursday, January 17). That's the stock's biggest one-day advance since mid-August. The S&P, on the other hand, dropped almost three percent in its worst day this year.
Berkshire's stock has been moving lower in recent weeks, and even with today's gain, it's still down 12 percent from its all-time closing high of $149,200 on December 10.
