Maybe the MM's that might be short have flooded the process in hopes of getting one of theirs as the MM to be quoting the stock once it returns to trading this week. That would allow them to controll the PPS while possibly covering any short that might be there.
I didn't even know that there were 54 MM around. I've never seen that many listed on any stock I've tracked. Of course...this is CMKX land so I guess it's possible!
