Correlation between overnight index futures and the next day's market behavior

I'm trying to find websites, articles, or academic papers that research the relationship between overnight index future movements and its effect on market sentiment the following day. Can ya'll help me out? Also interested in your own take on whether there is anything to gain from following futures as a means of more efficiently trading indices.
