ABB stock closed at USD 34.10 on the NYSE on September 21, 2026, up 2.45 percent from the prior session’s close. Compared with the S&P 500, which gained about 0.80 percent on the day, ABB outperformed the broader U.S. market by a clear margin.
September 21, 2026 in numbers
ABB Ltd (ISIN CH0012221716, NYSE: ABB) opened the regular session at USD 33.40 on the NYSE and traded in a range between an intraday low of USD 33.30 and a high of USD 34.25, before settling near the top of that band by the closing auction. The close left ABB’s U.S.-listed shares roughly 6.00 percent below their 52-week high of USD 36.30 and about 18.00 percent above the 52-week low of USD 28.90, keeping the stock in the upper half of its yearly corridor. On its Swiss home market, ABB had already advanced earlier in the day, with the shares up around 2.7 percent at the official close on SIX at about 11:35 a.m. ET, a move that reflects both local demand and the prevailing exchange rate between Swiss francs and U.S. dollars.
After the bell today and next session
In after-hours trading on September 21, 2026, ABB stock was last quoted at USD 34.15 on the NYSE Arca electronic venue at 5:22 p.m. ET, a modest 0.15 percent above the official close, indicating a stable extension of the regular-session gains. According to Yahoo Finance, ABB’s next scheduled earnings release is on October 20, 2026, which remains a key upcoming catalyst for the shares as investors look for updates on orders, margins and guidance. The next U.S. trading day after September 21, 2026 will be September 22, 2026, when ABB stock will again take its cue from overnight developments in global industrial and automation peers as well as movements in the S&P 500.
