Warren Buffett says the market’s recent declines mean nothing to his investing approach, and says Berkshire Hathaway has been adding to its positions recently. “It really doesn’t make any difference to us,” Buffett said on CNBC’s Squawk Box when asked about the market declining . “We were buying stocks on Friday, and we’ll buy the same stocks today, and we’ll buy them a little cheaper. So I never complain about buying things cheaper.” Buffett also offers his take on the European crisis, saying that he’s still open to investing in Europe despite the crisis.
