UBS has raised concerns over Tesla's recent market surge, which added over $350 billion to its market cap post-election, attributing it to market excitement rather than real business advancements. Analysts warn that potential policy changes could affect Tesla's competitiveness, especially if consumer tax credits for electric vehicles are eliminated. Despite maintaining a "sell" rating, UBS increased the price target for Tesla shares from $197 to $226, while the stock recently traded at $348.10, down 1.27%.
