Is Kinsale Capital Group, Inc. overvalued or undervalued?

As of 14 November 2025, Kinsale Capital Group, Inc. has moved from an expensive to a very expensive valuation grade. The company is overvalued, as indicated by its P/E ratio of 27, which is significantly higher than its peer CNA Financial Corp. at 14.82 and Unum Group at 13.25. Additionally, Kinsale's Price to Book Value stands at 7.01, and its EV to EBITDA is extraordinarily high at 1842.81, further highlighting its inflated valuation compared to industry standards.
In the peer comparison, Kinsale Capital's PEG ratio of 1.86 also suggests that its growth prospects do not justify its current price relative to peers. While the company has shown strong returns, the absence of recent stock vs. S&P 500 return data limits a direct performance comparison. Overall, Kinsale Capital appears to be overvalued in the current market context.
