To build a concentrated portfolio you need to know -
- Understanding of business & industry dynamics
- Your own investment time frame
- Ability to value a business.
- Brain wiring to handle volatility (This one being the most important)

What I’m doing is “betting on stocks where losing money is difficult.”, instead of trying to betting on making money.
