On Jun 30, 2016, Chubb Limited (NYSE: CB ) reached a 52-week high of $130.77. The upside in the stock was most likely driven by favorable rating assessment from the rating agency A.M.Best and the recent dividend hike by the company. Investors' confidence in the stock has been cemented as A.M. Best reiterated the financial strength rating of A++ (Superior) of most subsidiaries of the company. The rating agency also removed the subsidiaries from under review with negative implications. Investors are highly optimistic on Chubb after it was acquired by ACE Limited. This led to the formation of a global leader in commercial and personal property and casualty insurance, with an exceptionally balanced product portfolio, a broad and deep global presence, extensive distribution channel capabilities, and the ability to serve a diverse array of commercial and personal customers.
