Aon to grab market share amid marsh reshuffle, analyst says

Aon Corp., the world's second-biggest insurance broker, will probably win market share as larger rival Marsh & McLennan Cos. reshuffles its management team, an analyst at Stifel, Nicolaus & Co. said today.

"This period represents an excellent short-term opportunity for Aon as Marsh struggles to reassert itself," analyst Meyer Shields said in a research note.

Shields rates shares of Chicago-based Aon a "buy."
