Last night I posted this picture of the SEP put option chain for Tuesday (9/16) and also had the visual open interest configuration which showed the huge put block at the SEP 67 strike (at the bottom). This of course stood out as it was a huge signal for a bearish DXD trade since someone was willing to pay $952,700 to have the option to sell 952,700 shares at $67, or $63.8 Million, if it was in the money. The crazy part of it is the option was actually IN THE MONEY TODAY! The DXD closed today at $65.50 down 7.25%! So did anyone end up getting paid here?
Obviously there was some kind of trading error at the options exchange, but these are important market signals and should be right. By the way if you want to learn about this read McMillan on Options by Lawrence McMillan.
