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.

KNSLKinsale Capital Group, Inc.
Insurance - Property & Casualty · $336.98 · beta 0.87
Why now
Insurance - Property & Casualty · market cap $7.7b. Down 29% from 52-week high of $477.02 — deep drawdown territory. Revenue growing +18%, comfortably above the S&P median. 9 sell-side analysts rate this a Hold with a mean 1-yr target of $349.44 (implying +4% upside).
Moat
Net margin 28% sits well above the S&P median (~11%) — suggests structural pricing advantage or cost discipline competitors can't quickly close. ROE 30% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. 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.

Common questions

Is WTM or KNSL the better stock?

WTM scores higher: WTM 80.0, KNSL 77.0 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 WTM and KNSL 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.
