Following up on that, updated the S&P 500 futures graph for the past two weeks. Cyan is market hours and open, yellow is futures and close. Gain/loss calculated using open/close on the 1 min graph, respectively, and net gain is shown in green red. Results:

>Days w/ Drop on Open: 10/15
>Days w/ Drop on Close: 10/15
>Average of the Pre-market Movement (Magnitude): 1.32%
>Average of the Market Hours Movement (Magnitude): 0.72%
>Average of the Percent of Pre-market Movement Comprising Daily Net Gain/Loss: ~70%
>Days in Which Market Hours Followed Futures: 11/15
>Bullish Market Hour Divergences (Irrespective of Daily Net Gain/Loss): 1/15
>Bearish Market Hour Divergences (Irrespective of Daily Net Gain/Loss): 3/15
>Gain/Loss From 4/8 Open to 4/29 Close: +9.56%
>Attributable to Pre-Market Movement (Assuming Validity of Point #5): +6.69%

To clarify the 5th point, it simply states that ~70% of the daily net gain/loss on any given day is attributable to pre-market movements.

Including today, we have not had a day in which the market hours movement has vastly outweighed the pre-market movement since 4/8, on which pre-market movement was +1.05% and market hours movement was +2.20% (over two times as much).
