The stock hit a trading peak of $291 in September, 2014. It has been highly volatile since then, moving up and down based on news about the company's ability to produce and sell its electric vehicles in the US and other markets, especially China.
Over the past six months, analysts who cover the stock have offered a wide range of price targets, ranging from a low of $65 to a high of $400, with a variety of other numbers in between. The tremendous run-up in share prices from 2013 to mid-2014 was driven by optimism about Tesla's growth prospects.
But since late 2014, Tesla has shed billions in market cap as Wall Street has figured out that the company's ongoing story is as much about building one car in one factory as it is about a startup trying to disrupt a 100-year-old-plus industry.
