All that said I feel Tesla is a good company but if I was focused on them I'd just as well look for shorting opportunities. If it's not evident, I'm a fan of short selling.
Personally I'm the opposite -- I only go long for the long term. But that's what I decided my risk tolerance was as a mid 30-year old. So far my long position in TSLA since late 2013 has been a pretty good result.
For any investment, one simply can not know everything. I gave TSLA up for another area which as paid well. I use to own in Google after the IPO, even during my ownership I would short at times. The same is true with any stock I'm long. If there is an opportunity that I'm comfortable with then I take it.
I think too often people talk about short selling without any real experience doing it. So often it's realities get distorted with chatter. 2008 I learned to short basically during hands on learning as there just wasn't any great opportunity when things were going crazy. There were other great opportunities, my personal favorite was the government shut down under Obama and the predictable re-opening. That was some glorious profiteering right there...
"Short sellers who believe shares of are due for an imminent decline are paying a hefty price to place their bets, with some shelling out what amounts to an annualized cost of between 90% and 120%" http://blogs.wsj.com/moneybeat/2016/09/22/teslas-short-selle...
The fact that Tesla rebounded after hours is neither here nor there. The shorts may have already paid out.

White = information easily available to the public. Say, like SEC filings or press releases.
Grey = information between white and black. For example if you over heard a CEO mention something vague to a colleague at a bar and think you can act on it.
black = clearly material insider information
I don't follow. Tesla is down 1.4%. People who shorted Tesla made money today. Plus a lot of people made money shorting Amazon over Amazon's life.
Shorting a stock has less to do with a company's business plan/success and more to do with predicting the market itself and how they'll respond to various quarterly results (and the likelihood of such results).
Tesla is mostly just prop in the stock market "game."
