Tesla's Elon Musk has poked fun at short sellers as his electric-car maker's stock surged to a record, vaulting its market value past century-old rival Ford.
"Stormy weather in Shortville..." the chief executive officer tweeted on Monday US time, as Tesla shares climbed as much as 5.8 per cent. The maker of Model S sedans and Model X crossovers saw its capitalisation surge to about $US48.2 billion ($63.4 billion), $US3.1 billion more than Ford, the No. 2 car maker in the US after General Motors.
