KNSL vs PLMR: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: PLMR is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. KNSL and PLMR share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined KNSL and PLMR exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Kinsale Capital Group is a specialty property and casualty insurer focused entirely on the U.S. excess and surplus (E&S) lines market, the segment that handles hard-to-place commercial risks the standard admitted market will not write. It underwrites a broad spread of commercial lines (property, excess casualty, small business, construction, allied health, professional liability, commercial auto, and environmental) plus a small personal-lines book, distributing exclusively through independent brokers across all 50 states. Its structural edge is a proprietary technology platform that lets it run an expense ratio near 20 percent, well below peers, which supports consistently profitable underwriting and returns on equity in the high-20s percent range.

Palomar Holdings (NASDAQ: PLMR) is a specialty insurer that underwrites property and casualty risks across five product lines: Earthquake, Inland Marine and Property, Casualty, Fronting, and Crop, plus a fast-growing Surety and Credit business. It started as a residential and commercial earthquake specialist in catastrophe-exposed states like California and has since diversified into less catastrophe-correlated lines to smooth earnings. The company writes business directly and also operates as a fronting carrier, and it leans heavily on reinsurance to cap its exposure to large seismic and hurricane events.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• KNSL drivers: Structural low-cost advantage; E&S market tailwind.
• PLMR drivers: Broad-based premium growth; Strong underwriting margins.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Valuation has been the largest single risk, and the stock's roughly 18 percent decline over the past year shows how quickly a premium multiple can compress when growth slows, even with earnings still rising. For PLMR, the largest risk is catastrophe exposure: a major California earthquake or an active hurricane season could generate outsized losses despite reinsurance.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick KNSL if you believe its drivers more; PLMR if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the KNSL and PLMR guides.

KNSL. Kinsale's trailing P/E has fallen to about 15 from the high teens earlier in 2026 as earnings grew and the share price slipped, though it still trades at about four times book value, a premium that reflects sector-leading return on equity and a low combined ratio. The forward multiple near 17 is higher than the trailing one because analysts expect 2026 and 2027 operating EPS of roughly $21.40 to $21.70, below trailing GAAP earnings. Q3 2026 results are due October 22, 2026, with consensus near $5.11 of operating EPS. Figures are approximate and move with each quarterly report.

PLMR. Palomar has kept beating estimates, with Q2 2026 adjusted EPS of about $2.36 against about $2.21 expected. At $139.62 on October 16, 2026 the stock trades at about 19x trailing and about 12x forward earnings and about 3.7x book, a premium to many insurance peers that reflects its premium growth and high return on equity. The 52-week range was about $100.81 to $147.62, and the six analysts covering it average a target of about $159.

Headline figures (approximate, October 2026): KNSL shows revenue (ttm) ~$2.0B (Q2 2026 up ~17% YoY), gross written premiums (fy2025) ~$2.0B, net income (ttm) ~$569M, combined ratio (fy2025) ~75.9%; PLMR shows revenue (ttm) ~$1.09B (~55% growth in latest quarter), net income (ttm) ~$203M (~18.6% margin), q2 2026 adjusted eps ~$2.36 vs ~$2.21 expected, q1 2026 gross written premium ~$630M (up ~42% YoY).

KNSL and PLMR are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
