I've noticed that the IWM refuses to budge, even in the face of general market weakness. For instance, right now the QQQQ are down about 0.7% whereas the IWM is virtually unchanged.
Below is a line chart of the IWM, SPY, and DIA on an intraday basis for the past 120 trading days. As you can see, the IWM has defied any push downward. Since I am short mostly small caps, I certainly hope this gap gets erased.
