$NVAX Not sure if the article on the $100 put options are putting a damper on today's prices. It just seems the people who got in below $100 are trying to buy some protection. If you look at the other side of the coin, there's a Huge Huge open interest on the $300 calls - it's the biggest at 4,217 contracts. The $240 and $270 open interest are also huge. I'm also surprised by the $440 calls .. big open interest. So we are seeing even bigger open interest on the Call side.
