Humans are wired for action. Most employers pay people to "do" things at work each day. Doing something is productive; not doing something is lazy. Stock prices rarely stay the same day after day. 24/7 news, social media, and CNBC are a constant feed shouting, "Do something!" Even in investment management, the management fee is justified when there is investment activity. After all, what am I paying you for? Michael Mauboussin called it the rub between the investment business and the investment profession. The professional may say "no" to an investment, but the business may push the professional to invest anyway. Further, firms with teams of investment analysts, presenting investment ideas hoping they will be implemented, may be discouraged by the "Abominable No-Man" as portfolio manager.
In investing, however, when there is nothing to do, the investor should do nothing. Doing nothing goes against human nature, cultural norms, employment expectations, and the investment "business." It is a simple idea, but not easy.
“If there's nothing to do, do nothing.”
“For most—almost all—of the lifetime of an investment, you should be doing nothing about it. The bulk of the activity of investing is waiting.”
“'You make your money by the waiting.' Now that doesn't mean sitting around for the next depression; you can't do that, but a fair amount of patience is required in some of these good investment records. Patience followed by pretty aggressive conduct when the time comes. Imagine sitting there, we're [Daily Journal] having all of this money rolling in with the foreclosure boom, and then deploying it in like one day...It wasn't luck that we had the money on hand when other people didn't, and were willing to deploy it when other people were running for cover.”
“There are huge mathematical advantages to doing nothing.”
“Make a few great investments and sit on your assets.”
“We continue to make more money when snoring than when active. Inactivity strikes us as intelligent behavior.”
