Tesla is on track for its worst annual performance as a publicly traded company

Shares have been cut in half since Musk's "funding secured" tweet
On August 7, 2018, Musk tweeted, "Am considering taking Tesla private at $420. Funding secured."
He then posted a follow-up tweet that said shareholders could either sell at $420 a share "or hold shares & go private." That day, shares climbed as high as $387.46 apiece. They have since fallen 50%.
That initial declaration sparked a monthslong battle with the Securities and Exchange Commission, which was eventually settled in April.
