The /ES looks to open around 1640 after closing at 1654 yesterday. It hit an overnight low of 1632 and a high of 1658. Some of the weakness is a result of the Fed meeting yesterday and the 7% drop in Japan overnight.
Base on the weakness, I think going with some $GS 155 puts is the best risk/reward play this morning. The stock looks to open around 156ish.
