JPMorgan Chase and Wells Fargo have reported stronger-than-expected earnings, signaling resilience in the US consumer sector. JPMorgan posted a surprise gain in net interest income and raised its revenue outlook, buoyed by a 29% surge in investment banking revenue. Despite a 2% decline in net income due to increased provisions for potential bad loans, the bank exceeded Wall Street expectations, leading to a 5% jump in its shares. Overall, major US banks, including BlackRock and BNY, topped Q3 earnings estimates, contributing to record highs in financial sector stocks.
