I've mentioned this before, but it bears repeating: Tesla (TSLA), having lost over a fifth of its market cap from its high, is vulnerable in two important ways: one, it can't seem to get its act together with the Model X (which was initially shown years ago, and to this day still isn't an officially-launched product) and two, it's not like the rest of the world is idly sitting by while Tesla owns the entire high-end electric car market. Audi, for one, has a Model S killer coming out in a couple of years. I think one can expect this stock to be beneath $200 by the first quarter of next year.
