Valued at a market cap of $87.1 billion, Aon plc (AON) provides a range of risk and human capital solutions worldwide. Based in Dublin, Ireland, the company offers commercial risk solutions, retail brokerage, specialty solutions, global risk consulting and captive management, and more.
Companies worth $10 billion or more are generally described as “large-cap stocks”, and Aon fits right into that category, with its market cap exceeding this threshold. Given Aon's extensive clientele including numerous corporations, pension funds, endowments, and foundations, its valuation above this mark is unsurprising.
AON recently touched its all-time high of $412.97 on Mar. 3 and is currently trading 2.4% below that peak. Meanwhile, AON stock has climbed 6.6% over the past three months, significantly outperforming the Nasdaq Composite’s ($NASX) fall of 8.4% during the same time frame.

AON's performance looks even more impressive over the longer term. AON stock soared 15.8% over the past six months and 27.3% over the past 52 weeks, compared to NASX's 9% gains over the past six months and 11.8% returns over the past year.
AON has been trading above its 200-day moving average since late July 2024 and its 50-day moving average since late January 2025, indicating an uptrend.

Despite delivering solid financials, AON's stock dipped marginally after the release of its Q4 results on Jan. 31. Driven by notable organic growth and the impact of acquisitions, the company reported an impressive 23% year-over-year growth in its total revenue to approximately $4.1 billion. Furthermore, driven by notable expense discipline, its net income for the quarter increased 45% year-over-year to $734 million. Meanwhile, its adjusted EPS increased 14% year-over-year to $4.42, exceeding the Street's expectations.
AON outperformed its top competitor Arthur J. Gallagher & Co.'s (AJG) 10.1% surge over the past six months. However, AJG has outperformed AOW with a 29.7% surge in its shares over the past 52 weeks.
Analysts remain reasonably bullish on AON’s prospects. The stock holds a consensus “Moderate Buy” rating among the 22 analysts covering it. As of writing, AON is trading slightly above its mean target of $395.21.
