The stock of next-generation bank and financial services company Nu Holdings (NYSE: NU) got some new momentum on Monday. In a very brief regulatory document filed with the Securities and Exchange Commission (SEC) on Saturday, Nu Holdings wrote that it "hereby informs its shareholders and the market that neither the company nor any of its subsidiaries have any exposure to Silicon Valley Bank." Silicon Valley Bank, the core business of SVB Financial, is of course the latest high-profile banking sector meltdown.
