Key insights
- Kinsale Capital (KNSL), a niche insurer focused on non-standard risks, is trading at its cheapest forward P/E on record despite strong underwriting margins and a 20-fold increase in share price since its 2016 IPO. The company's focus on underwriting profits, disciplined growth, and AI-driven efficiency, combined with a large addressable market, suggests continued growth potential. This positive outlook for a specific company in the insurance sector could signal broader investor confidence in the financial sector.

Kinsale underwrites non-standard risks that other insurers don’t want on their books and still manages to post underwriting margins most peers can only dream of.
It’s founder-led, focused on a single niche, and has been executing the same philosophy with discipline for more than a decade.
Kinsale sells a “Collect Now. Pay later” type of product. This generates the so-called “float”, which the insurance company can use to generate investment income. Think of “float” as an interest-free loan from policyholders that the insurer uses to make more money. That’s why an insurance company has a double-profit-engine.
Kinsale sits in one of the most attractive corners of U.S. P&C and has quietly turned it into a compounding machine. Since the IPO in 2016, the share price is up more than 20-fold, powered by old-fashioned underwriting profits and disciplined growth.
The niche Kinsale serves is insuring risks that the standard market does not want. Kinsale insures “hard-to-place”-risks, as these insurance coverages are anything but standardized products. Economically, Kinsale is built on volume, selectivity and cost discipline using their own in-house integrated built AI tool.
In an industry that, on average, barely breaks even on underwriting over a cycle, Kinsale has consistently posted combined ratios in the mid-70s.
Capital allocation has been a priority. Reinvesting into the core underwriting discipline as long as attractive opportunities are available and keeping leverage conservative. The business is capital-light, benefits from float, and has grown EPS at ~40% per year over the last decade. The future look bright, with management stating 10-20% growth runway for the next decade.
Despite its phenomenal success over the last one and a half decades, Kinsale today has a market share of ~1.6 %. The growth runway is still huge. But if Kinsale can preserve its underwriting edge and continue to take share in a still-fragmented E&S market, it has the ingredients of a long-term compounder.
