A bull and a bear both offered pessimistic views of Tesla stock after the automaker reported its Q1 deliveries, which provided the first look at its business this year. JPMorgan analyst Ryan Brinkman, the bear, cut his forecast for Tesla's earnings to 30 cents a share down from a previous estimate of 43 cents and below Wall Street consensus of 39 cents, according to FactSet. Brinkman added that he sees 60% downside to his price target of $145 a share and maintained his sell rating.
