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
RNRRenaissanceRe Holdings Ltd.
Why now
Insurance - Reinsurance · market cap $13.7b. Trading near 52-week high of $335.97 — momentum setup, limited technical margin of safety. 15 sell-side analysts rate this a Hold with a mean 1-yr target of $346.40 (implying +5% 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 21% 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
Trading within 2% of the 52-week high — limited technical margin of safety; a momentum reversal would test conviction. 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

Moat
Net margin 38% is exceptional — pricing-power territory rare outside premium software, branded staples, and specialty pharma.

Financial moat — scale of deposit base / underwriting franchise plus regulatory capital advantages. The largest players compound book value through cycles that erase smaller competitors.
