Chubb Limited (CB) Stock Analysis & Winston Score
Chubb Limited is one of the largest property and casualty insurance companies in the world. It sells insurance policies that protect people and businesses from financial losses caused by accidents, natural disasters, lawsuits, and other risks. Its main customers range from wealthy individuals to large multinational corporations, and it is especially well known for high-value home, auto, and commercial insurance. Chubb makes money by collecting premiums from policyholders and investing that money while it waits to pay out claims. The company operates in over 50 countries, with major business in North America, Europe, and Asia, and generates roughly $50 billion in annual premiums. Its competitive edge comes from strong underwriting discipline — meaning it is careful about which risks it agrees to cover — and a well-established brand among affluent and corporate clients. The key risk the business faces is a rise in large catastrophe events, such as hurricanes or wildfires, which can quickly increase claims and pressure profitability.
