Growth against the P/E multiple. Up and to the right is cheaper and faster — the quality-growth idea in one picture. Points beyond the axis are pinned to the edge and marked off-scale rather than allowed to compress everything else.

The companies
BRK-BBerkshire Hathaway Inc.
Insurance - Diversified · $520.59 · beta 0.59
Why now
Insurance - Diversified · market cap $1.1T. 3% off the 52-week high of $537.74. 3 sell-side analysts rate this a Buy with a mean 1-yr target of $547.67 (implying +5% upside).
Moat
Net margin 22% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 12% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. $1.1T market cap places it among the largest companies in the sector — distribution, R&D, and customer-acquisition costs amortize across a base peers can't replicate.
Risk
Balance-sheet financial — book value, net interest margin, and credit loss provisions are the lever points; a rates regime change or a deterioration in the loan book moves the stock more than EPS does.

Moat
ROE 13% meets the long-run market sustainable threshold — solid but not differentiated; the durability comes from elsewhere. Financial moat — scale of deposit base / underwriting franchise plus regulatory capital advantages. The largest players compound book value through cycles that erase smaller competitors.

Balance-sheet financial — book value, net interest margin, and credit loss provisions are the lever points; a rates regime change or a deterioration in the loan book moves the stock more than EPS does.

Common questions
Is SLF or BRK-B the better stock?
SLF scores higher: SLF 73.0, BRK-B 65.0 out of 100 on the Bull Rankings quality-growth score, which blends business quality, growth and valuation into one number. A higher score means a stronger business at a more reasonable price — it is not a price target or a recommendation.
How are SLF and BRK-B scored?
Each carries the same 0–100 quality-growth score used everywhere on the site, built from three pillars — quality (profitability and returns on capital), growth (revenue and earnings), and value (what you pay for them) — combined as a geometric mean, so a weak pillar cannot be papered over by a strong one.
