Aon Heads Into Q1 Print With Options Hedging Picking Up

Aon reports first-quarter results on May 1 with options traders showing the clearest sign of caution the stock has seen in weeks.

The put/call ratio jumped to 0.83 on April 27 — nearly two standard deviations above its 20-day average of 0.74, and the most defensive reading since March. That shift contrasts with a relatively quiet short-selling picture: short interest is a modest 1.1% of the free float, and while it spiked roughly 19% in a single session on April 24, the absolute level remains low. Borrow costs have actually eased, dropping 13% on the week to 0.35% APR, and utilization — at 0.38% against a 52-week high of 1.98% — is far below any level that would suggest meaningful squeeze pressure. The stock itself closed at $323.78, up 0.8% on the day but down 2.5% on the week after a solid 3.2% gain over the past month.

The Street's orientation is broadly constructive, though analysts have been trimming targets into the print. JP Morgan maintained Overweight while cutting its target from $406 to $396, and Wells Fargo held Overweight with a more meaningful reduction from $443 to $402 — both moves reflecting macro caution rather than company-specific concern. The mean target across the Street is $390, implying roughly 20% upside from current levels. Bulls point to Aon's revenue momentum — the last report showed 10.5% top-line growth to $4.15 billion — and to the company's leadership in insurance-linked securities, with $50 billion in outstanding catastrophe bond placements. Bears focus on margin delivery: adjusted operating margin came in at 28.2% last quarter against an expected 29.0%, and macro headwinds in financial services, construction, and M&A-driven demand remain a live concern.

The ownership picture adds a subtle wrinkle. Dodge & Cox materially added to its position in Q1, with a net change of roughly 4.4 million shares — the largest move among top holders. Berkshire Hathaway, by contrast, trimmed by approximately 497,000 shares as of year-end 2025. The net insider picture over the past 90 days shows a positive $15.3 million balance, though the recent trades in March were small, routine award-and-sell transactions rather than conviction purchases.

The May 1 print will therefore test whether Aon can close the gap between its revenue trajectory and its margin execution — with the options market signalling investors are less certain about the answer than they were a month ago.
