As discussed here and here, The Dow Jones World Index moved lower retracing most of the rise from May 2010 to May 2011, as noticed in the weekly chart above.
The downtrend had an impulsive 5-wave structure (see the daily chart below) which may have ended in the beginning of October setting up an a-b-c correction which can run until perhaps end of November or early December. When this rebound is over, the longer term downtrend could resume.
