Company snapshot — Aon PLC

AON in five paragraphs: what it makes and sells, where it sits in the Closelook stack, who it is priced against, why we track it, what we watch. Research diary, not advice.

What it does
Aon is a professional services firm that brokers insurance and reinsurance, advises on risk and human capital, and runs retirement and investment programmes for corporate and public clients. It works through two segments, Risk Capital and Human Capital, covering commercial risk brokerage, health and wealth advice, reinsurance placement and pension administration. Its clients include corporations, public pension funds, endowments and foundations across the Americas, Europe, the Middle East, Africa and Asia Pacific. It is headquartered in Dublin, Ireland.
Where it sits in the stack
Aon carries no seat in Rubin, the diary's index for the AI build-out; it sits instead in the insurance-broking part of Closelook's wider financial-services universe, alongside firms that price and place corporate risk rather than supply compute infrastructure.
Who it is priced against
The diary holds no peer group for Aon in this sleeve; the comparison the market draws most often is with Marsh McLennan, the other large insurance and reinsurance broker.
Why Closelook tracks it
Aon's only listed index seat is the S&P 500; it carries no Closelook score and appears in none of the diary's editions or quotes, so it sits outside our AI-linked coverage.
What the diary watches
The diary watches whether the recent slide below the 50-day and 200-day levels, alongside the cut to the analyst target, reflects a broader repricing of insurance-brokerage margins or a shorter-lived move confined to this one name.
