Volatility's the watch word in Tesla Motors' stock price.  Peter Garnry, Saxo Bank's Head of Equity Strategy, says short sellers have been running for the doors in recent days.

The company's just announced it's going to triple the number of supercharger stations across the US. That could be a game changer since drivers will be able to travel longer distances without worrying about running out of power.

So where's the value? And how can Tesla Motors ever meet expectations on its return of capital?
