I noticed that some options have strike prices that don't exceed the current market price of the underlying stock. Why would this be? For example, GameStop doesn't have any strike prices above $60 for February 12. I would think, even if no one was selling calls, that the volume and open interest would simply be 0 but there would still exist such contracts.
If I go to March 5, the open interest is blank. What does this imply?
