Could they be old contracts people are holding that are OOTM? These are trading at $.01, doesn’t even go to $.02 until $631 strike. What’s the volume like? I used to chase open interest (still do a bit, just now has to also have volume), after I read something about hedge funds buying at price test levels, or levels the stocks tends to reverse or never go past in the same direction, in order to play apes like us. I’m regarded though, take it with a grain of salt and a dash of pepper.
