I've been tracking a strange thing in the market the past couple of weeks that seems to be a constant.
IWM is always more bullish than RUT on a percentage basis, seems to be about .10% more bullish. For example right now RUT is is down .38% while IWM is down .27%.
The interesting thing is that this does not exist in SPY/SPX they run about the same percent wise.
I'm going to keep tracking this into and through a down trend to see if it changes or not.
