U.S. banks were clobbered Friday after the United Kingdom voted to leave the European Union in an unprecedented vote.
Shares of Goldman Sachs sank more than 7 percent, while Morgan Stanley's stock dropped more than 10 percent. JPMorgan Chase and Bank of America were also hit by the U.K. vote, trading about 7 percent lower.
The SPDR S&P Bank ETF (KBE) also fell about 7 percent.
That said, Christopher Semenuk, portfolio manager at TIAA Global Asset Management, isn't too negative about this reaction.
"Given the event, [this] isn't nightmarish," he told CNBC via telephone. "I think the reaction in banks around the world, not just the U.S., isn't too bad."
