A likely result of the high-tension tug-of-war between the longs and the shorts. Tesla is efficiently priced due to its large short-position, but the S&P Index Committee has refused to add it to the S&P 500, so it lacks the liquidity that most S&P 500 stocks have. Which means it can be pushed around a lot on seemingly minor news and rumors. Interestingly, any strategy that tries to profit from this will tend to boost liquidity, making the stock more stable.
So 0 line is $297?
