Orin's take
0.62conviction · moderate
Refreshed 17 Aug · take v8. A new filing or a print queues the next refresh.

Aon's FY2025 results are undeniably strong — EPS surged 36% to $17.02 on 9.4% revenue growth to $17.2B, free cash flow expanded to $3.2B, and total debt was cut by $1.4B to $16.5B — yet the stock's ~8% pullback from the mid-$370s to $347.22 has only marginally improved the setup. At 19.5x trailing earnings AON trades at a 36% discount to the peer median P/E of 30.5x, but that discount reflects modest ~5% organic growth and a sub-1% dividend yield that cap the multiple.

Smart money has just turned slightly positive (score 0.0091 as of Q2 2026) after a year of outflows, yet persistent insider selling by the General Counsel at $360–380 and the CFO at $343.56 in July 2026, combined with a bearish MACD histogram of -2.40, argue for patience until technicals stabilize near the 200-day MA at $337.

What could go wrong

  • Insider selling acceleration. General Counsel Zeidel executed multiple sales in July 2026 at $360–380, and CFO Reese sold 2,198 shares at $343.56 on July 1; 24-month net insider value is -$29.2M despite positive net share count of +49,618.
  • Valuation ceiling from modest organic growth. Seeking Alpha (2026-08-10) notes ~5% organic growth and sub-1% dividend yield do not justify a premium multiple; P/S of 4.29x is 28% above the peer median of 3.36x, limiting re-rating upside.
  • Bearish technical momentum. MACD histogram at -2.40 with the signal line at 2.86 vs. the MACD line at 0.46 indicates downward momentum; price at $347.22 is below the 50-day MA of $348.62.
  • Leverage remains elevated. Total debt of $16.5B against stockholders' equity of $9.35B yields a debt-to-equity ratio of ~1.8x as of FY2025, constraining financial flexibility despite the $1.4B reduction from FY2024.

What would change my mind

Technical stabilization at 200-day MA. Price holds above $337 (200-day MA) with RSI recovering above 50 and MACD histogram turning positivebullish
Q3 2026 organic growth acceleration. Organic growth exceeds 6% with operating margin expansion, confirming the NFP acquisition integration is delivering synergiesbullish
Break below 200-day MA. Close below $337 on volume, signaling loss of institutional support and opening path to the low-$320sbearish

Two scales, drawn separately on purpose: a sector median and one company’s multiple are not the same number and putting them on one axis invites a comparison neither series supports.
