Today is the 1st of November and the start of a new month. I’m just trying to grab some stats on how the first trading day of the month has been from January 2005 until July 2012.

The average opening from yesterday’s close: +0.066%

The average gain from yesterday’s close until today’s close (if today is the first trading day): +0.142%

The average gain from the open to the close: +0.073%

Here is the return from open to close if SPY opens up:
