$HYLN - the bulk of the option activity is on $20 calls expiring on Friday 2/26. Will be interesting to see if they let it go over $20 or try to hold it under $20 until Friday so options expire worthless and then let it run. Either way the pressure is building and the market is betting this is going up from here. Current put/call ratio open interest ratio is .25. Be patient but aware that there is a lot of motivation by MMs to keep this under $20 until after Friday. I believe this is one reason it has sold off so quickly once it hits $20. Once it breaks this tipping point, $25-30 should not be too far behind. Good luck this week!
