What Happened?
Shares of specialty insurance provider Kinsale Capital Group (NYSE: KNSL) jumped 4.4% in the afternoon session after a director disclosed significant open-market purchases of company stock, signaling strong insider confidence.
According to a filing, director Gregory Share reported buying shares on December 15, 2025. After the transactions, the entity through which the shares were purchased held 32,000 shares of Kinsale common stock. The stock's rise was also supported by a broader market rally after key inflation data came in cooler than expected. The November Consumer Price Index (CPI) rose less than economists had forecast, causing major indexes to surge.
Adding to the positive sentiment was significant activity in the specialty insurance sector. Howard Hughes Holdings, backed by billionaire Bill Ackman, entered an agreement to acquire specialty insurer Vantage Group for approximately $2.1 billion. This deal highlighted a trend of investors viewing well-positioned property and casualty platforms as attractive.
After the initial pop the shares cooled down to $394.02, up 4.2% from previous close.

What Is The Market Telling Us
Kinsale Capital Group’s shares are somewhat volatile and have had 11 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The previous big move we wrote about was 6 days ago when the stock gained 1% on the news that the company announced its board of directors authorized a new $250 million share repurchase program.
This new authorization followed the completion of a previously announced $100 million share repurchase program. Share buybacks can indicate that a company's leadership believes its stock is a good value. By purchasing its own shares from the open market, a company reduces the total number of shares outstanding, which can increase the value of the remaining shares. The company's Chairman and Chief Executive Officer, Michael P. Kehoe, stated that the announcement reflected confidence in Kinsale's future and the value management saw in the stock.
