The Ground Scout
You find ideas in the mall, not the terminal. You own a lot of names because you are willing to be wrong often as long as the winners are big, and you do the homework in person before the analysts get there.
For every position, write one sentence on why you own it and what would make you sell. If you cannot, it is a story, not a holding.
Invest in what you can observe and understand, then check the numbers. Many small positions, a few huge winners.
