Tesla CEO Elon Musk slammed Wedbush Global Head of Technology Research Dan Ives on twitter telling him to "shut up" after Ives suggested the board limit Musk's political activity. The tweet comes during a turbulent week that saw shares in the electric vehicle-maker plunge after the billionaire businessman announced he's forming a new political party.

Dan Ives, an analyst with Wedbush Securities, wrote that Musk's continued push into politics was "exactly the opposite direction" investors wanted to see.

Tesla shares dropped 7% on Monday amid a renewed public feud between CEO Elon Musk and former U.S. President Donald Trump, alarming investors already wary of the electric carmaker's political entanglements and slumping sales.
