I'm talking about a possible scenario of player(s) with a vested interest in the fossil fuel economy trying to impact Tesla's path, not some hedge funds looking to turn some money on a Tesla play.
In this scenario I'm talking about pooled massive massive wealth that would not blink at dropping $10 billion by 2020, or $25 billion to use your idea of a bullish 2020 TSLA price rather than mine.
If all of this has been going on, probably most of the downward influence below fair value has already been spent, reinforcing the false notions that Tesla is a bubble stock, cult stock, stock with no rational justification for it's stock price, etc. etc. ("one of the 3 most shorted stocks..." repeated over and over helps with that), which I find it all but certain have depressed TSLA's price both pre-2013, when Tesla very well could have gone under without more funding, and from 2014-2017 when the stock was basically sideways, and Tesla just completed a capital raise with the stock about 35% below what I considered fair value when it traded at $250.
In this hypothetical scenario, I think such players will keep that, let's say, "strategic" position a few more years, and back out of it gradually. They would want to minimize the appearance of "the shorts" capitulating, to minimize the sense that the bears were wrong, bulls right, and we've already made steps into the Tesla future. They may be fine holding such a short until it's plainly obvious to almost all that EVs are the future (likely in the early 2020s) rendering continuing the short position pointless. Don't get me wrong, even in this speculative theory, I think there are many other shorts, and they may well capitulate quite a bit soon, as is often discussed on this forum, but, the players I'm speculating about would likely want to avoid adding to the specter of such a large closing of short positions in such a small timespan reading out as "it's over, the bulls had it right."
This is all theoretical, so we could discuss this on and on, what' likely more interesting is just to watch the size of that short position. Let's see if it finds a home below 10% before 2020 or not. My sense is not, though I don't have strong conviction about that or this whole theory... my confidence is something over 50% on all this, but, not strong conviction.
