Mistakes happen, and the sooner you realize it the better. Sometimes, it turns out that a business isn’t what we thought it was when we purchased the stock. Maybe it faces tougher competition than you thought or its positioning is getting worse, not better.
British economist John Maynard Keynes famously said that when the facts change, you should change your mind. Admitting mistakes can be hard, but you’ll be better off as an investor if you can realize them quickly and get out of your position.
