Extremely low PCR with high volume MSOS but only on 3/20 option chain

I've been watching the put call ratio and open interest for MSOS on the 3/20 expiry for over a week. There is a massive amount of call buying and huge volume compared to other dates. The PCR has been holding .05 for days which is like a 20 to 1 difference. The volume is also massive but only on that one date. Volume drops off dramatically the following week which also seems unusual. There is volume all the way up the options chain from the $4-$10 strikes. Looks like a big ramp.

My guess is someone is front running the rescheduling EO that was signed in December. It just so happens that exactly 90 days from the signing is next Wed 3/16. This is significant because the EO's typically have a 90 day window for review before they are put into law.

Can somebody check this for me to see if you are getting the same numbers? The cost to borrow is low and shorts have 2.24 days to cover. Also last Friday somebody was doing some big buying right at close, if you check the volume on that day you will see it.

I know rescheduling seems unlikely in the current political environment but this anomaly seems pretty wild and given that insiders tend to do well lately maybe this is something or maybe not??
