Bank of America CEO Brian Moynihan said trading revenue will be “relatively flat” compared with last year’s third quarter, a break from the surge that Wall Street saw in the first half. The news sent shares of Bank of America and other big banks falling.

Following that news, Moynihan spoke with Bloomberg’s Dani Burger from the sidelines of Barclays Global Financial Services Conference in New York and talked about the bank’s outlook, his thoughts on guardrails for artificial intelligence and more.
