Bank of America CEO Brian Moynihan said on Monday that third-quarter trading revenue would be "relatively flat" compared to the same period last year, and that investment banking fees are expected to be between $1.6 billion and $1.8 billion, below analysts' previous estimate of $2 billion. Following his remarks, Bank of America's stock price fell by nearly 6% during intraday trading, making it the worst-performing stock in the KBW Bank Index for the day. Goldman Sachs and Citi's stock prices also fell by 4.3% and 4.2%, respectively.
