FULL TRANSCRIPT: BILLIONAIRE INVESTOR WARREN BUFFETT SPEAKS WITH CNBC’S BECKY QUICK ON "SQUAWK BOX" TODAY : WARREN BUFFETT: Yeah, selling a stock because it goes down. I mean, you know, if you buy your house at $20,000 and somebody comes along the next day and says, "I'll pay you $15,000," you don't sell it because the quote's $15,000. You look at the house or whatever it may be. But some people are not actually emotionally or psychologically fit to own stocks. But I think more of them would be if you get educated on what you're really buying, which is part of a business. And the longer you hold stocks, the less risky they become, whereas the longer the maturity of a bond, the more risky it becomes.
