UBS analyst Joseph Spak has raised Tesla's price target to $226 from $197 while maintaining a 'Sell' rating, citing concerns over the speculative nature of its AI initiatives, which he believes inflate the market cap by nearly $1 trillion. He estimates that Tesla's auto and energy divisions contribute about $52 per share, with the rest driven by AI optimism. In contrast, Dan Ives from Wedbush Securities views Tesla as undervalued in the AI sector, highlighting its Full Self-Driving technology as a significant opportunity, while Morgan Stanley reaffirms a 'Buy' rating, praising Tesla's self-driving capabilities and responsiveness to pro-charging policies in the U.S.
