I did study on the OEX ( it applies also to the XEO) for the last 40 months history , from Sept 02 to 12/16/05.
One month = option expiration to option expiration
Here are some of my findings if you are interested:
The biggest monthly loss was -44.54 . It happened on 9/20/02 and the 2nd biggest monthly loss was -28.87. It happened this year on 10/21/05
The biggest monthly gain during that period was 30.19 on 11/18/05 the second biggest settlement was 28.49 on 12/19/03 .
The biggest intra-month low was 49.57 during the month of 2//03 and the second biggest intra-month low was 47.95 during the expiration month of 9/02.
The biggest intra-month high was during expiration months of 6/03 and 11/04 36.95 points and 36.87 points respectively.
The second biggest intra-month high was during expiration month of 11/05 total points of 30.71.
I thought it might give you guidance for your trades.
