Pabrai lays out the mathematics of why stock picking is so brutal and yet so rewarding for the small group who master it [1] — Mohnish Pabrai "Only 4% of US companies have driven the entire stock market's 90-year return. Buffett made 400+ investments but just 12 created Berkshire. …" 1:06:22 . Over 90 years of US stock market history, just 4% of companies have generated the entire cumulative return. The other 96% have broken even or lost money. Warren Buffett's personal track record is a perfect mirror: 300-400+ investments made over 60 years, but just 12 of them created Berkshire Hathaway. A hit rate of 3-4%. The corollary is Pabrai's 'circle the wagons' concept: in a world where capitalism's competitive destruction forces almost every business toward zero, the rare businesses that build genuine moats — McDonald's brand, FICO's entrenchment, Coke's global taste — must be held forever. Not selling Coke. Not selling Apple. Not firing Ajit Jain. Those non-actions were worth more than all of Buffett's hundreds of other decisions combined. The future is the same: Pabrai doesn't know which half of his current bets work, but a 40% hit rate produces a home run, and the ones that work compound for decades if he doesn't touch them.
Over the last 90 years, just 4% of US companies have delivered the entire stock market's cumulative return; the other 96% have merely treaded water.
Only 4% of US companies have driven the entire stock market's 90-year return. Buffett made 400+ investments but just 12 created Berkshire. The index wins because it's too dumb to sell NVIDIA. Beating it requires knowing which 4% you're in — and not selling them.
