Meanwhile, Tesla shares have been on the decline for months, sinking 8.1% Tuesday. Musk himself revealed he'd sold 20 million Tesla shares, worth about $3.5 billion, in a security filing last week. Analysts have cut their price targets on Tesla stock, Reuters reported Wednesday, fearing weak demand from China will impact the EV maker's delivery abilities. For many Tesla investors, the reason for the share price isn't a mystery. Ross Gerber, a major Tesla investor, tweeted Tuesday that the "Tesla stock price now reflects the value of having no CEO," and that it's "time for a shake-up." "Please tell us your great ideas, Ross," Musk mused in a response tweet. Gerber followed up with three : Tesla needs a media and communications team; it needs a succession plan and clarity on Musk's potential return; and it needs to communicate about Musk's stock sales.
