Like playing chess, sometimes I guess how would the opponents think. Among all hardcore short holders, I think many of them regret what they did in the past few years. Tesla didn't bankrupt quickly as they expected. On average, shorts have to pay 6~10% a year to borrow the shares, that's significant if they have to hold 10+ years. Some of them buy Puts instead, the time decay is even more damaging for their accounts. Think about those holding 2018 Puts, TSLA has to drop 50% for them to just break even (depends on their strike price). The recent model 3 reservation is horrible news for them. After all, maybe EV is not a niche market anymore? Maybe the longs are right? On the other hand, large institution investors are very happy, they buy a chunk of TSLA, lend them to the shorts, earn a nice interest. If the stock goes lower, they buy more and lend to the shorts. At some point, there will be no more shares for shorts to borrow. But longs can keep buying. Shorts have no chance to win the fight. This is likely to turn into a slow Tsunami. Shorts took huge risk for a small potential return.
