The thesis, from the filings

WATSCO INC earns about 32% on invested capital, far above its ~9% cost of capital, but has diluted owners by 7% over 5 years — a real edge showing up in the numbers. The estimate methods put fair value between $146.63 and $223.03 a share.Whether it’s worth owning at today’s price is the last question — and yours to answer, below.

It earned about 32% on invested capital, year after year, against a ~9% cost of capital — the footprint of real pricing power. Competition usually drags returns like this back down; here it hasn't.

Share count is up 7% over 5 years — owners have been diluted. Worth asking what they got for it.

Signals, not verdicts — read from the filings above. Numbers don’t prove a moat; they show its footprint. You decide.

iv. What it’s worth — engine v0.1.0

The 3 estimate methods that apply put fair value between $146.63 and $223.03 a share. They rest on different assumptions, so where they diverge is the story; the Graham Number is a stricter floor, not a target.
