August 29, 2026
Benzinga revisits Aon’s long-term returns: a $100 investment 15 years ago. Benzinga published a retrospective looking at how a $100 investment in Aon 15 years ago would have grown today, putting recent trading in the context of the company's long-term share performance. The piece is a historical review rather than a forward-looking call, but it highlights how Aon has rewarded patient shareholders over a multi-year horizon. Current trading sits inside the stock's 52-week range of $304.59 to $382.34, with a P/E of 19.8 and a 0.92% dividend yield, while the average analyst price target of $402.47 is above the recent range. The takeaway is that Aon's long-term track record is back in the news, even as the stock is consolidating in the middle of its yearly band.
