There was a very large trade on the options chain today.
$1 strike may 20th puts...5,000 contracts were sold.
Then
$1 strike June 17th puts....5,000 contracts were bought.

If the price stays below $1 by tomorrow that first trade will have the shares put to them.
Then if that same trader owns the shares they can exercise the short position on the ladder trade.

I don't quite know what to think of this but it should interesting real soon
