First Republic and Credit Suisse shares drop despite increased capital.

Shares of First Republic Bank and Credit Suisse tumbled despite receiving pledges of emergency funding aimed at shoring up their beleaguered finances. The decline in the banks' stocks resumed downward slides that were interrupted on Thursday. The drops come after First Republic shares gained on Thursday, while Credit Suisse shares were unchanged, reflecting a short-lived reprieve amid deepening concerns about the industry following the sudden collapse last week of Silicon Valley Bank and Signature Bank.
