Elon Musk has told Tesla employees not to “bothered by stock market craziness” after shares in the company plummeted.
In an internal email to staff, Mr Musk reportedly said that he still believes Tesla will become one of the most valuable companies in the world in the long-term.
The Tesla CEO also urged employees to help increase deliveries of the car at the end of this quarter after the automaker offered reduced prices for its vehicles in the US and China.
“Please go all out for the next few days and volunteer to help deliver if at all possible. It will make a real difference,” he said in the message, which was obtained by Reuters.
“Btw, don’t be too bothered by stock market craziness. As we demonstrate continued excellent performance, the market will recognize that.
"Long-term, I believe very much that Tesla will be the most valuable company on Earth!"
In the last six months, shares in Tesla have fallen from a high of $309 (£256) to $112.71 (£93) a share at the time of writing - last year the shares had been priced at $399 (£331).
Some analysts have attributed the loss in value to Mr Musk’s £36.6billion purchase of Twitter in October.
Tesla also cut production of some of its models after demand for electric cars slowed in China.
Despite this, analysts expect the company to deliver 442,452 vehicles in the fourth quarter.
