Gardan,
It was not my intention to imply that you have provided irrelevant information, it is actually useful. What I am saying is that the stats themselves may well be irrelevant if the average rise has not provided enough of a profit potential for traders.
The US election might well change that but then there are statistics for election years (not that I can recall what they are). We must remember that there are those that use such data for trading purposes and some of them make a decent profit from their activities.
