Charles Schwab (SCHW) said Tuesday that profits soared 32% from a year ago, fueled by record client trading activity during a busy quarter for Wall Street. Total net revenue increased 21% to $7.1 billion, driven in part by a 28% rise in trading revenue. "During the second quarter, strong client engagement helped drive year-over-year revenue growth," Schwab CEO Rick Wurster said in a earnings release statement. Sharp price swings, heavy stock rotation, and rising investor balances helped stock trading desks deliver a blowout second quarter. Schwab stock was flat following the Tuesday print.
