I think FB is undervalued right now but with its Instagram, Whatsapp, and potentially, Calibra, it can be over performing stock soon. Crosshair shows the price level at 2019 Q1. It should be much much higher than the crosshair line.
Despite company's hardships and bad news, no one really sees TESLA as a typical stock. This is more of a gambling stock. The chart doesn't make any sense. It will only make sense to those who like to gamble and take advantage of its volatility.
