Foraging for BRKB

It was a nice coincidence that on the same day I bought BRKB stock I learned about the optimal foraging equation. What’s great about this is the ability to tweak different variables to affect the value.

From a decision making perspective, investing is super interesting. People like Michael Mauboussin, Shane Parrish, and Patrick O’Shaughnessy explain important ideas simply. However, investing is super difficult. 

The optimal foraging equation is why target date 401k funds work so well. The ‘calories gained’ value may be moderate but the ‘expended’ and ‘time’ values are also quite low.
