Morgan Stanley cut its "worst case scenario" for Tesla , citing the company's rising debt levels and geopolitical exposure. The firm's price target for the stock remains at $230/share, with an "equal-weight" rating.

"Moving our bear case to $10 from $97 previously. Given the increased debt load, geopolitical exposure (demand increasingly dependent on China), and potential for negative news flow to impact fundamentals, we have lowered our bear case valuation for Tesla. Our previous $97 bear case was based on 70% EV/Sales applied to our 2020 revenues of the company. Our revised $10 bear case is based on a 31% EV/Sales ratio applied to our unchanged 2020 revenues. We believe a reduction of this magnitude in the EV/Sales ratio is fair given the combination of execution, economic and political risks facing Tesla's 2020 revenues and a retrenchment in global auto share prices heading out of 1Q19 results. For perspective, a 31% EV/Sales ratio would still be at a substantial premium to the average European auto OEM ratio of 22% (including BMW at 28% and Volkswagen at 17%) and would also be a premium to the average US OEM EV/Sales valuation of 25% on our 2020 revenue forecasts."
