Since the collapse of SVB Financial and Signature Bank, a lot of bank stocks have been sold off significantly. One of those is the large digital consumer bank and auto lender Ally Financial (NYSE: ALLY), which is down about 18% since SVB started struggling earlier this month. Investors have had their doubts about Ally for many months now, as the company's large retail auto-lending portfolio looms large heading into what could be a much tougher economy for consumers.
