$IWM out of sync .. why ?

IWM has been going south since late June and we are seeing a lower low. As at Aug 19, it is sitting below MA200, which is very different to DIA, SPX and QQQ.

Lack of strength in IWM and I expect further downside. As you can see, the 1st range down took 24 cd and the retracement up to 33% took 18 cd (both numbers are divisible by 6).

Target = 201.
