Charles Schwab said a surge in trading activity by its brokerage customers helped lift second-quarter profits by 60%. The company joined other banks and brokers in benefiting from a busy and volatile spring marked by investors’ reaction to President Trump’s ongoing trade war.

Charles Schwab beat forecasts for earnings and revenue, and shares traded at a record high. The discount brokerage and investment firm posted big gains in trading revenue and net interest income, and total client assets reached an all-time high of $10.76 trillion.

Charles Schwab (SCHW) stock climbed 2.2% in Friday premarket trading after Q2 earnings and revenue beat Wall Street expectations as core net new balances grew 31%, sweep cash rose, and the company continued to reduce its bank supplemental funding.
