I would also add that not only does the next 2-3 months not look like it will be dominated by negative bearish sentiment, but this run up wasn't really based on major hype or big product announcements either, leading many of us to conclude that it was driven mainly by slow and steady institutional accumulation.
Yes, this is the biggest part of the answer. Another part of the answer is that with the higher volumes and with the increase in buying by longs, the shorts lost their ability to manipulate the SP. We saw the mandatory morning dip disappear, we saw capping activity fail more often than it succeeded, and the slow drift down into closing gave way to the second wind of buying by mid-afternoon. These changes in short activity had a profound effect upon the SP. Finally, I love the expression that TSLA is a manic-depressive stock, and down days tend to favor more down days and up days tend to favor more up days. I would say that overall TSLA is still in a manic phase and buyers will be ready to return once they're convinced that the SP has bottomed out from the Q4 ER dip.
Taking one giant leap backwards, one needs to consider the reasons why institutions started buying back in and shorts started to be less successful with their manipulations. It comes down to fundamentals. The institutions weren't going to buy more TSLA until the Tesla-SolarCity merger issue had been resolved, and once it was resolved, that roadblock disappeared. Shortly afterwards, we saw the positive Q3 ER; the presidential election resolved with a clear electoral college winner (could you imagine the Hillary and Trump's battle if the results were questionable and the effect a constitutional crisis could have upon the broader markets?), and finally we saw the gigafactory event for the media and big investors, which opened their eyes to the fact that the gigafactory would indeed begin generating revenues shortly. So, ultimately, it was these changes in both Tesla and the perception of the market about this being a good time to buy TSLA that led to the institutions buying in, the shorts losing their magic in manipulations, and the manic-depressive meter swinging to manic.
BTW, the signal that things had fundamentally changed was when the shorts, using all their tools, could not push TSLA below 180 and have it stick. Once the willingness of buyers to accumulate at 180 exceeded the ability of the shorts to manipulate the stock down any further, we had a clue that the momentum of TSLA had changed in a very important way.
