BMO stock closed at USD 177.20 on the NYSE on September 21, 2026, up 1.55 percent from the prior U.S. session based on exchange data. Compared with the broader S&P 500 index, which posted a smaller percentage gain on the day, the shares outperformed the U.S. market benchmark. The move followed a constructive tone in Canadian banking names and a firmer home-market performance for Bank of Montreal in Toronto earlier in the day.

Bank of Montreal Inc. (ISIN CA0636711016, NYSE: BMO) opened the U.S. regular session at a level moderately above its prior close, then traded within an intraday range that kept the closing price near the upper end of the day’s band per NYSE data. The advance from the prior close of USD 174.49 translated into a gain of USD 2.71 on the day, while the percentage move left the shares closer to their recent 52-week highs in U.S. trading. On the Toronto Stock Exchange the stock had already finished the last completed session on September 18, 2026 higher, rising 0.44 percent at the close according to Ad-hoc-news, supporting sentiment for the U.S.-listed shares.
