The acquisition sparked investor concerns, including whether he would be distracted from running Tesla or divert resources to the social media company."He might have needed the money to really finalize the Twitter deal but restructuring the company and righting the ship is going to prove to be more costly than he probably expected," OANDA senior market analyst Ed Moya said.The latest sale brings the total amount of Tesla stock sold by Musk since last November to about $36 billion - despite his having said earlier that he would sell no more of his shares.Musk, said Ives, needs to end "Twitter overhang on the Tesla story with his focus back on the golden child Tesla which needs his time more than ever given the soft macro, production/delivery issues in China, and EV competition increasing from all corners of the globe."Musk last month closed the deal with $13 billion in loans from banks and a $33.5 billion equity commitment, which included $7.1 billion from investors, including Oracle Corp (ORCL.N) co-founder Larry Ellison and Saudi Prince Alwaleed bin Talal."
