is obviously a strong index, and expected with conservative risk to keep growing until the first quarter of 2018. This is not guaranteed, but definitely looks like the most possible outcome.

Since it is about to complete its third wave plus the way finance is about to become rapidly disrupted with the blockchain as well as even more precious metal commodities
, the status isn't fully known. There can be continued downward trends or at least some negative correlations after the first quarter because of the third wave completion. However, the status for a long is yet to be professionally determined.
