Arthur J. Gallagher stock (ISIN US3635761097) traded at USD 230.57 on the NYSE on September 22, 2026, down 2.55 percent from the prior close of USD 236.61. The move leaves the shares 26.47 percent below the 52-week high of USD 313.55 and USD 39.82 above the 52-week low of USD 190.75.
Market value remains substantial

A separate September 21, 2026 market snapshot recorded a closing price of USD 236.61 and a market capitalization of USD 60.65 billion. The difference between the two market-capitalization figures reflects the different trading dates and quote states rather than a new operating result.
Latest reported figures remain relevant
Arthur J. Gallagher's latest operating figures are not used here without a clearly evidenced reporting period. The current market data nevertheless provide three dated reference points: the September 22 price of USD 230.57, the 2.55 percent daily decline and the 52-week range of USD 190.75 to USD 313.55.
For investors, the main measurable issue is valuation sensitivity after the stock moved 26.47 percent below its 52-week high. The company remains valued at more than USD 59 billion on the September 22 market snapshot, so changes in earnings expectations can have a material effect on the share price even when daily trading volume is below its average.
