Wedbush's Dan Ives is back and has a message for Tesla (TSLA) bears: Go back into hibernation mode. Ives has a $300 price target on Elon Musk's E.V. company. Looking ahead to Apple (AAPL) and its A.I. features, Ives sees the company as a "major A.I. player for years" but says Tesla is actually the "most undervalued A.I. play" right now.
