September 18, 2026 in numbers
Allegion plc (ISIN IE00BFRT3W74, NYSE: ALLE) ended the September 18, 2026 session at USD 152.24 on the NYSE, with the price moving between an intraday high of about USD 153.05 and an intraday low near USD 151.53 according to a detailed S&P 500 component listing from Cinco Dias. At that close, Allegion stood about 21.8% above its 52-week low of USD 125.00 and roughly 16.8% below its 52-week high of USD 183.11, underscoring that the stock is currently positioned in the middle portion of its recent trading range, as highlighted by a MarketBeat-based summary recently reproduced by Ad-hoc-news. The same MarketBeat data set, as referenced in that report, indicated a market capitalization of about USD 12.95 billion at the USD 152.24 closing price, placing Allegion among mid-sized industrial security names in the US large-cap universe.
Trading volume for Allegion on September 18, 2026 amounted to just under 3.68 million shares according to the S&P 500 overview from Cinco Dias, a level that provided solid liquidity around the USD 152 zone. In the broader US equity market, reports on index performance for the same trading day showed the Dow Jones Industrial Average slipping modestly while the Nasdaq Composite advanced, reflecting a mixed large-cap backdrop in which Allegion’s 0.9% decline was moderate relative to more volatile technology names, as summarized in a US market wrap from TTV Finance.
Ex-dividend and macro cues today
Looking ahead to today’s session on September 21, 2026, dividend calendar data from eToro show Allegion with a declared dividend of USD 0.55 per share and an ex-dividend date on September 30, 2026, implying that the shares will trade without the right to that payout from that later date. While that ex-dividend event lies beyond the immediate trading day, it sets a near-term corporate milestone that some income-oriented investors may already factor into positioning ahead of the open today. In the wider environment, recent US market commentary has emphasized sector rotation between cyclical industrials and higher-growth technology and semiconductor names, a backdrop that can influence demand for building-security and infrastructure-related companies such as Allegion as market participants balance defensiveness and growth exposure heading into today’s trading.
