Chinese electric car company NIO (NIO) is due to report its Q1 earnings on April 29, and Mizuho analyst Vijay Rakesh is optimistic -- rating the stock a "buy" with a $60 price target. (To view Rakesh's track record, click here) As the analyst advises in his recent note, NIO grew its deliveries more than five-fold year-over-year in March, to about 20,100 vehicles, as production of its ES8 and EC6 SUVs ramped -- far faster than the global car industry's production growth of 16%, or the 77% increase in China unit sales, either one. And NIO's sales exceeded its own published prediction of 19,500 deliveries.
