Investment Philosophy

This portfolio is built around one idea: own wonderful businesses at fair prices and hold them long enough for compounding to do the work.

We apply Peter Lynch's six categories as a filter. Stalwarts provide stability. Fast Growers provide returns. Turnarounds provide occasional asymmetry. Cyclicals and Slow Growers are avoided unless the price is extraordinary.

The account mandate is simple: buy quality, add on weakness, never sell unless the thesis is broken. Price is not a thesis.

Horizon: 2042.
