PacWest's Fate Hangs in the Balance as Regional Bank Stocks Slide.

Shares of regional banks, including PacWest, Western Alliance, and First Horizon, rebounded in premarket trading after a week of steep drops. The collapse of First Republic earlier in the week had raised concerns about deposit outflows, but PacWest stated it had not seen any unusual outflows. The rapid drops in stocks have led some to suspect foul play by traders, and the American Bankers Association has asked regulators to take action against market manipulation and abusive short-selling practices.
