"We're an automotive tech company," Tesla CEO Elon Musk told CNBC Thursday on the automakers plant floor in Fremont, Calif. "I'm not a fan of trying to pump the stock or trying to convince people the stock should be higher, or even convince people the stock should be where it is now. I actually think the value of Tesla right now, the market is being very generous and it's obviously giving us a lot of credit for future execution." Investors are betting that Tesla can expand sales from a projected 21,000 this year to well over 100,000 in three to four years when the company rolls out a lower-priced third-generation car. So there's a lot of execution risk built into the bullish sentiment surrounding Tesla right now. Nobody is more aware of that risk than Musk.

"We need to make sure we knock the ball out of the park in the coming years."
