First Republic slid nearly 33% to end the week down close to 72%. The Dow Jones Industrial Average lost 384.57 points, or 1.19%, to close at 31,861.98 points. The S&P 500 slid 1.10% to end at 3,916.64 points, while the Nasdaq Composite was down 0.74% to 11,630.51 points. Stocks fell Friday as investors pulled back from positions in First Republic and other bank shares amid lingering concerns over the state of the U.S. banking sector. "The Fed seems to be paying lip service, at least, and being aware of what just happened with the banking sector," said Aoifinn Devitt, chief investment officer at Moneta.
