You've taken that out of context. You would have better served your readers if you had included Musk's follow-up comments:
"II think we need to make sure we knock the ball out of the park in the coming years."
"The market obviously goes through these periods of exuberance and depression. That means our stock has a lot of volatility because it depends so much on what people believe our future execution will be. Our stock price is obviously far too high based on historical financials, or even on current financials, ... So the value is very much based on what the future cash position will be like... as that confidence waxes and wanes we'll see fluctuation in the value of the company."
Unlike most CEO's, Musk is a straight shooter. He's incredibly innovative and driven to succeed. I wouldn't bet against him turning Tesla Motors into the world's largest and most profitable automaker.
He again defers to the future. As any magician knows, re-direction is key to the illusion.
Where are the "we are..." messages versus the "we will try to do..." stuff going on now.
If they were based only on current finacials without the irrational (IMO) view of the production numbers some people post here - the stock is roughly "fairly valued" at $72-75.
