Buffett Quality Screen

Buffett's "wonderful business" criteria, quantified into six dimensions: earnings record (20), ROE quality (25 — Fortune's double standard), low leverage (15), pricing power (15), business stability (15) and capital efficiency (10), for a 0–100 total. The entry gate is the first of Berkshire's acquisition criteria — at least $50M average pre-tax earnings over the last three fiscal years (banks and insurers excluded, as leverage is their business model; investment trusts and closed-end funds excluded, as they are portfolios rather than operating companies). Recomputed periodically from each company's last ten fiscal years; cross-listings merged by canonical ticker. Hover the score for the six-dimension breakdown; companies we cover link to their report. Filtered by score tier "Medium", profit streak "≥5 yr", Has report: 114 match(clear filters) · page 2 of 2.
