Imagine this: A well-known stock analyst recommended a good stock to buy. As soon you heard about it, you bought it. But as soon as you bought it, it went straight down. In cases like this, we usually blame the person who recommended the stock. Whether he’s a friend or foe, it doesn’t matter. Although that’s normal, it’s not totally right. Maybe he recommended it for the long term, and you bought it because you wanted to make a quick buck. When he said long term, he actually meant five years, not one. Or maybe he recommended it as one of many in a diversified portfolio, but you went all in on the stock.
Things might have also changed after a month. He might have recommended a restaurant stock, not expecting a pandemic to strike. So the whole investment thesis might have changed. In short, he could be playing a different game.
