Analysts wonder how the IPO of the unprofitable electric carmaker will fare over the long term. GM, by comparison, is steadily gaining market share around the world, most notably in China -- the world's largest auto market.
Still, that hasn't prevented investors from putting their faith in Tesla's sleek, electric, Model S sedan, which they believe will be a huge hit when it comes to a market they apparently believe is craving fuel efficiency and seeking relatively affordable cars that fulfill this need.
Tesla is already taking reservations for the roughly $50,000 Model S, which is expected to come to the market by 2012.
