I think our market is more obsessed with pre-empting the DOW, rather than reacting to its previous day (unless a really big move).
And as it has been such a huge yoyo of late (up day 1, down day 2, up day 3, down day 4 etc etc) it means if DOW is green we go red in anticipation of their next trading day, or if DOW is red we go green etc. Obviously just a generalised observation and it also depends on the levels of moves (and a million other factors).
