1/ We have often suggested options markets are a big influence on $TSLA share prices, both up and down. For those of you perpetually mystified by Tesla's trading patterns, this 5 year open interest graph was interesting to us. Open interest keeps climbing. Now at peak levels. 
2/ Not every stock shows steadily increasing OI numbers. Here's a 5 yr for AAPL, NFLX and NVDA. NVDA plateauing after a spike, NFLX and AAPL surprisingly low.
You can do the math for yourselves. But this OI volume in $TSLA and the shape of the curve is not benign and clearly has had (and will have) an impact on underlying share volatility. There is a lot of OI in Tesla options relatively speaking. It is worth watching.
sorry, here is NVDA.
