Hubris Factory
“The real secret to investing is that there is no secret to investing. Every important element of value investing has been made available to the public many times over, beginning in 1934 with the first edition of Security Analysis.” Investing is enticingly easy to monetise. You get cost centres (need money) and profit centres (make money). A good business is one where you have something that is easy to count and communicate. “I’ll grow your money” fits the bill. Pricing is also easy with, “I’ll take a percentage”. The two key elements are good capital allocation (what work the money does) and reversion to mean (prices typically overreact and true normal is less noisy). The downside of all this simplicity is that investing is a hubris factory. The real work gets done by the underlying businesses, but investors often think it is an extension of classroom exam results (which also oversimplify the process of ranking people). An Investor’s entire career of being a rock star can come tumbling down with factual evidence that they have done no better than average. They’ internalise the good times and excuse the bad. The real secret of investing and good businesses is that it is not about you. It is about putting money to work, and reinvesting. Custodianship, not proof of worth.

One More Step
“Fitting the
curve” is when you take the results of an exam and change them to fit what is “normal”.
Through squashing, stretching, and standardising unexpected shapes. If a group
has an average, almost no one is average. A Standard Deviation is the average
amount each result is different from average. Again, almost no one is the
average amount different from average. “Normally”, about 68% of results sit
between one Standard Deviation below and one Standard Deviation above the
average. 95% sit between two below, and two above. 99.7% between three down,
three up. That we do this for exams results shows that the goal is not
education. It is sorting. Most education is designed to find your role in the
world. This is the exact opposite of what we should be doing, and limits
everyone to their starting point. Like Samwise Gamgee, the step you need to
take is to realise the story is not about you. Education should be about
understanding, and solving, the problems in the world. And financing the things
that aren’t problems, but need money. At some point, you need to take the vital
step that snaps the connection to the constraints you don’t find helpful.
