This is why I purposely train myself not to stare at my portfolio every day. I want my emotions connected to changes in the business rather than changes in the quotation. I want to follow revenue, margins, customers, competition, capital allocation and management. Those are the things that ultimately create value. Ironically, many investors spend most of their time watching the one thing they cannot control while spending very little time studying the things that actually determine long term value. Then they wonder why investing becomes so emotional. Constantly checking prices also changes your time horizon. You may buy a company because of what you think it can become over ten years, then six months later you are worrying about what the stock will do after next quarter’s earnings. Without realizing it, you went from thinking like an owner to thinking like a trader. A 10% decline feels enormous when you stare at it all day. It feels much less important when the real question is whether the company can become five times larger over the next decade. Your time horizon changes the meaning of almost everything. Watching prices constantly also creates a temptation to manufacture decisions. The stock is up so maybe I should sell, the stock is down so maybe something is wrong, an analyst downgraded it so maybe I missed something. Activity starts feeling like intelligence. Usually the highest level investing decision available to you is doing absolutely nothing. You found a wonderful business, the thesis remains intact and the company continues compounding. There may simply be nothing for you to do. Some of the greatest investments of my life did not go straight up. There were ugly drawdowns, bad quarters, terrifying headlines and long periods when the market disagreed with me. The money was not made by predicting every short term move. The money was made by being right about the business and staying around long enough for that reality to matter. That sounds simple, but psychologically it is incredibly difficult. Markets constantly tempt you to interrupt compounding. I want to know immediately when the business changes. I want to know when competition changes, management changes, unit economics deteriorate or the opportunity ahead becomes materially smaller. Those things deserve my attention. If the stock falls 7% because someone somewhere changed their opinion, I do not care at all. If an analyst downgrades it, I want to know whether they discovered something important rather than what their new price target is. If an insider sells stock, I want to understand the context before assigning meaning to it. Price obviously matters. It matters enormously when you buy, when you sell and when valuation becomes disconnected from reality. But price should inform your decisions rather than control your emotions. The goal is not to ignore information. The goal is to become extraordinarily good at separating information from noise. I believe that ability becomes more valuable the longer your investing horizon becomes. Stocks move constantly, opinions change constantly and analysts change targets constantly. Businesses generally change much more slowly. If you want to become a better long term investor, learn which one deserves most of your attention. 2/2🌹
