CFRA's Garrett Nelson makes the argument that valuations continue to remain too high for Tesla (TSLA) with the stock hinging on A.I. and autonomous driving. He makes the case for CFRA's sell rating and $325 price target for Tesla as Wedbush's Dan Ives maintains his buy and $600 target. Karl Brauer believes the company can deliver on Elon Musk's vision for the future. However, Musk taking the steering wheel is something Karl sees as critical to drive Tesla's bullish expectations.
