Zurich Insurance Group Ltd has received a downgrade to a "sell" rating by UBS due to a change in market sentiment towards the company.

The majority of the company's revenue comes from general insurance, followed by life insurance. In addition, Zurich Insurance Group also generates income from other activities such as network, investment, and market banking through Zurich Capital Markets, as well as reinsurance and asset management services.

The Farmers Group contributes a small portion of the income and focuses on risk selection, administrative management of contracts, premium collection, and portfolio management. This downgrade may impact investor confidence as the company manages its diverse portfolio of insurance and financial services.
