Now it’s a $20 bn company and it’s stock has skyrocketed by almost 5 times since the beginning of 2012. While Tesla has got 1% of monthly sales of Ford It’s stock is trading with P/E of 125 compared to 9.3 P/E of Ford. It’s kinda overvalued but still many shortsellers got burned on this stock and this irrational valuation may persist for some more time. http://www.businessweek.com/articles/2013-08-27/tesla-is-now-worth-20-billion
