I mentioned recently that with the momentum indicator in its present position, it seems my 4.9.16 projection of ~3600 SPX may not be all there is. I did some additional calculations and by two different methods came within 8-points of each other for my next favored high target... the first I've already mentioned, which was ~5071, the second is ~5079.
Below is the weekly SPX with a potential road map to the higher target, should Armstrong's "vertical market" come to fruition.
