“Some people should not own stocks at all because they just get too upset with price fluctuations. If you’re gonna do dumb things because your stock goes down, you shouldn’t own a stock at all,” said Buffett told “Squawk Box” in February 2018.
By comparison, “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],” added. “Some people are not actually emotionally or psychologically fit to own stocks, but I think that more of them would be,” Buffett said, if they were more educated on what they were really buying, which is part of a business.
