America's biggest bank is sounding the alarm on Tesla's historic value loss under Elon Musk. As Quartz reports, JPMorgan Chase said in a new note to clients that they've never seen anything quite like the massive value plummet at Tesla, which this week has lost billions as its CEO's politics become more toxic by the day. "We struggle to think of anything analogous in the history of the automotive industry," JPMorgan analysts led by Ryan Brinkman wrote, "in which a brand has lost so much value so quickly."
