Why is Arch Capital Group Ltd. (ACGL) stock moving?

ACGL closed at $109.14 on Nov 10, up about 6% from $102.69 on Oct 22, after an intraday high of $113.63 on Nov 5. The shares rose 2.8% on Nov 2 as analysts lifted price targets after Q3 results (Oct 28, the highest-volume day in the window at 2.88M shares). Recent targets include UBS at $125 (Buy), Wells Fargo at $119 (Overweight), Cantor Fitzgerald at $111 (Neutral), KBW at $106 (Neutral, reaffirmed Nov 10), and BMO at $105, while Evercore cut to $103 and Autonomous Research raised to $96. On Nov 5 the company raised its buyback authorization by $3.0B to about $3.6B, a capital-return signal. On Oct 30 Arch Insurance North America agreed to buy Premier Dealer Services, with terms undisclosed and closing expected by end-2026. Since Nov 5 the stock has pulled back to the $107-110 area on lower volume (about 1.6M shares on Nov 9-10 versus roughly 2.1M average), so the price now sits near the middle of the target range. The buyback and rising targets support the stock, but most ratings are neutral and the price already trades close to several targets.

News behind the analysis

About Arch Capital Group Ltd

Financials · Property & Casualty Insurance and Reinsurance

Arch Capital Group is a Bermuda-based company in the S&P 500 that sells insurance, reinsurance and mortgage insurance around the world through companies it fully owns. It stands out because it runs three businesses side by side: specialty insurance, reinsurance and US mortgage insurance. It also has a reputation for raising and cutting how much business it writes as prices across the insurance market go up and down.

How it makes money

Arch earns premiums in three areas. It writes specialty property and casualty insurance for businesses. It sells reinsurance, which is insurance bought by other insurers. And it provides mortgage insurance, which protects lenders if homeowners default; it became a major player there by buying United Guaranty in 2016. Insurance and reinsurance bring in most of its premiums, while mortgage insurance has historically made an outsized share of its underwriting profit. It also earns investment income on the large pool of premiums it holds before paying out claims. Its capital was about $27 billion as of March 2026.
