Euphoria would have to take hold with major progress in China Trade, Brexit, improving earnings and guidance, etc, for the overall market to continue this pace without a consolidation.
I expect a return to 2,950 around EoY 2019, but a rhythmic bounce up to 3,300 by May 2020.
Election based volatility will have a major impact. If Warren gets the nomination, expect another $2,850 test. If Biden or Buttigeg get it, expect to hold a similar upward rhythm.
Either way, the Great Bull will continue to run through 2020.
