One of the nicer things about BRK is it does NOT trade in a predictable range, has less correlation with the index than most of the other 499 companies, and its stock performs on the upside in a comparatively unpredictable, lumpy manner often with big spikes in short terms and long periods of stagnation…not an accident: management offers no guidance and no price support and no BS. The risk of being OUT of this stock for even very brief periods can risk missing most of the progress —even long term. Management likes the owner this behavior attracts. It’s not guidance/analyst driven and it frustrates the hell out of people who want to turn this into a casino table game.

Berkshire’s management behavior discourages alleged “investors” who seek predictable, forecastable wiggly line movements —its behavior encourages people who seek the far more predictable and far more odds-favored long term investing.
