Tesla shares dropped nearly 10 percent in after-hours trading after the Securities and Exchange Commission filed charges against CEO Elon Musk .

A docket entry in Manhattan federal court shows the SEC has opened a case against Musk. The SEC alleges that Musk lied when he tweeted on August 7 that he had “funding secured” for a takeover of the company at $420 per share.
