In my opinion, the most indicative relationships to watch in these graphs are:

1. Russell and S&P (IWM and SPY): Note how they have diverged in the month and week graphs.
2. Consumer Discretionary and Consumer Staples (XLY and XLP): Note how Discretionary and Staples fall on opposite sides of the Russell/S&P nodes in the 6-month and 1-year graphs, with discretionary tied more to the small cap Russell index and staples tied more to the large cap S&P index, as would be expected.  However, in the past week, the opposite is true, implying that consumer staples is more tied to small caps than large caps, and likewise inversely for consumer discretionary.
3. Energy, Industrials, and Utilties (XLE, XLI, and XLU):  Note how these three have slowly diverged over each progressive duration graph.  Normally factory production is directly tied to utility and energy utilization, but it appears that this correlation is not present in the short term.
