Musk mocks short sellers as Tesla passes Ford in market value

Tesla also topped Ford Motor Co. in stock market capitalization.

"Stormy weather in Shortville," Musk tweeted after Tesla's better-than-expected quarterly vehicle deliveries announced on Sunday sent its stock surging 7.3 percent to close at $298.52.

Tesla said it delivered a record 25,418 vehicles in the quarter ended March, a 69-percent increase from last year and edging past Goldman Sachs' forecast of 23,500 vehicles.

The Silicon Valley car maker in the past has missed production targets and its newest figures allayed fears of setbacks ahead of the hotly-awaited launch of its Model 3 sedan later this year.

"This beat shows that they are managing production better," said Ivan Feinseth, an analyst at Tigress Financial Partners.

Just under GM

Monday's surge in Tesla's stock gave it a market capitalization of about $48.4 billion -- surpassing Ford's $45 billion value and just below General Motor's value of $51 billion.

Musk is correct about the misery suffered by those betting against Tesla, a popular trade on Wall Street where skeptics say the company is in danger of being overtaken by older, deep-pocketed manufacturers like GM. Tesla proponents, meanwhile. are betting it will become a carbon-free energy and transportation heavyweight.

So far in 2017, Tesla short sellers have suffered paper losses of 27 percent, equivalent to $2.25 billion, according to S3 Partners, a financial analytics firm.
