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
ACGLArch Capital Group Ltd.
Why now
Insurance - Diversified · market cap $33.7b. 8% off the 52-week high of $107.09. Revenue growing +14%, comfortably above the S&P median. 19 sell-side analysts rate this a Buy with a mean 1-yr target of $111.87 (implying +13% upside).
Moat
Net margin 24% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 20% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. Financial moat — scale of deposit base / underwriting franchise plus regulatory capital advantages. The largest players compound book value through cycles that erase smaller competitors.
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.

Why now
Insurance - Diversified · market cap $1.1T. 6% 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 +8% 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.
