Baron Generational Growth Fund stated the following regarding Arch Capital Group Ltd. (NASDAQ:ACGL) in its Q2 2026 investor letter:

"We believe that there are two primary sources of this multiple compression. First is a "softening" of the property and casualty (P&C) insurance market, which has negatively impacted the valuations of Arch Capital Group Ltd. (NASDAQ:ACGL) and Kinsale Capital Group, Inc. After several years of consistent and elevated premium increases, premium prices in certain lines have flattened or declined. This is an inevitable but temporary phase of the P&C insurance cycle, as more capital enters the market to chase attractive ROE opportunities. Despite the softening market, both Arch and Kinsale are growing their written premium and book value per share through high returns on equity, market share gains, underwriting discipline, and attractive capital allocation strategies. We are confident that as the cycle inevitably turns again, premium growth will reaccelerate, and both stocks' multiples will expand."
