September 18, 2026 in numbers
Aon plc (ISIN IE00BLP1HW54, NYSE: AON) saw a relatively quiet session on September 18, 2026, with the 0.10% decline from the prior close leaving the shares near the lower end of their recent trading band but still comfortably above the one year low of USD 293.00 highlighted by MarketBeat. At the same time, the shares remained some distance below the one year high of USD 382.34 from the same source, underlining the gap to the top of the 52 week range.
According to a session wrap citing New York Stock Exchange data, Aon stock closed at USD 295.76 on September 18, 2026, down 0.10% in that session, while the broader United States equity benchmarks posted a mixed performance over the day, with large cap indices showing only modest percentage moves. The narrow decline therefore placed Aon close to the broader market tone rather than marking an outsized single stock move, and the closing level left the shares roughly 24.6% below an estimated intrinsic value of USD 392.17 discussed by GuruFocus on September 21, 2026.
Today’s catalysts and upcoming events
Into today’s session on September 22, 2026, attention around Aon centers on recent analyst support and the company’s positioning ahead of its next earnings release. On September 21, 2026, MarketBeat reported that Citigroup reaffirmed its buy rating on Aon and set a price target of USD 435, implying roughly 47% upside from the previous close and adding to a moderate buy consensus across the analyst community. That call, which references Aon’s recent quarterly results with adjusted earnings per share of USD 3.81 versus a USD 3.80 consensus and revenue growth of 2.2% year over year, may remain a reference point for trading today.
Broader market conditions also frame today’s session. A United States market review for September 21, 2026 from eOption noted that major indices had recently logged one of their better days since early August, which can support sentiment for diversified financial services groups such as Aon heading into the open today. No specific company events for Aon are scheduled within the next few trading days in the available corporate and earnings agendas, so short term trading is likely to key off ongoing analyst commentary and the broader movement of United States equity benchmarks.
