The Nasdaq has halted trading of Tesla's stock after a string of tweets by CEO Elon Musk suggested he's considering taking the company private, an unexpected announcement that bewildered even close Tesla watchers on Tuesday.
Shares of the Palo Alto-based electric carmaker had spiked more than 7 percent by Tuesday afternoon after Musk, who is known for his erratic public outbursts on Twitter, sent a cryptic tweet that said he's mulling taking the company private at $420 per share.
