Citation that people don't hold equities for more than four years?
I have held equities for more than four years. Most of my portfolio, actually. Daytrading and churning positions are for people with more time to devote to the market than I care to. But maybe I am fictional, as my grandmother gave me one of her BRKb shares in 2002 (which I still own).
The period that you measure someone's market performance is independent of how long they actually hold a single equity. Do you measure a day trader's performance over a single day?
Either way - it's a moot point - (Just like the investment funds you excluded) BRK doesn't need to turn over an equity to increase their value, whatever the time period. They could never sell anything and still give increased returns to their investors.
