RUN $20.78 and tanking fast...short idea, and anyone else that banks with SIVB .....SVB Financial Group , shut down by regulators on Friday after a run on deposits, is known for its close partnerships with tech companies. But it's also a lender to clean energy firms, including Sunrun (ticker: RUN), the largest residential solar developer in the U.S. That relationship appears to be impacting Sunrun's stock, which was down as much as 8.9% on Friday.
