North American Bank Stocks Plunge 5% Despite Strong Earnings and Share Buyback

Canadian Imperial Bank of Commerce (CIBC) closed at $109.50 on the New York Stock Exchange on the 27th, down 5.14%. Trading volume was about 1.12 million shares, and its market capitalization stood at roughly $101.5 billion (about KRW 140 trillion), erasing around $5 billion (approximately KRW 7 trillion) in value in a single day.

On that day, the bank reported second-quarter adjusted earnings per share of $2.54, beating market expectations, and announced the sale of its Caribbean unit to US-based Butterfield & Son for about $1.6 billion, reallocating capital toward its North American growth businesses. It also launched a normal course issuer bid to repurchase up to 30 million shares for cancellation. Despite the positive earnings surprise and restructuring news, the stock weakened as investors booked profits and braced for future risks.

Founded in 1961 through the merger of the Canadian Bank of Commerce and the Imperial Bank of Canada, CIBC is one of Canada’s Big Five banks, offering personal and commercial banking, wealth management and capital markets services in Canada, the United States and international markets.
