The Germans say, “you lost your virginity. Now you sign a contract; you say, ‘I’m a boring virgin.’ Be abstinent for the next two years. Show me your soul and two years from now, we’re going to get married. But today, I commit to marriage today? Forget it.”
The more frequently you monitor your portfolio, the more likely you are to observe a loss. This is likely to cause short-sighted decisions and could hurt your investment performance. If you are checking your portfolio more than once per quarter, you’re doing it too much.
