Personally I like a high short interest too as it does nothing but add fuel to a rally. You might be on to something regarding the Mercedes hedge, but whatever the case we are coming from a huge short interest, and the stock hasn't been budging to the point the shorts have been hoping for. We have only fallen below $200 for a short period in the last 10 months and the trend line is clearly going up. I think the short "community" is slowly breaking as they continue to be wrong about the stock and the story of Tesla is getting stronger by the quarter. The typical short argument of Tesla being "extremely overvalued" is slowing falling apart as Tesla ramps up production super fast, next year Tesla will only be valued at 4x revenue, and the year after 2x revenue, and that is high margin revenue. The shorts illusion is crumbling under the weight of reality and I think the trend of falling short interest (was 30mil a year ago) will continue.
Agree with your assessment, shorts are persistent but less and less so, they are slowly breaking and getting wiped with Tesla tsunami
