Trade wars fears, inflation, flat yield curve, slower global growth, the Fed hawkishness, etc. are all overblown.
Here's the facts:
"From 1933 to 2016, the average return for the S&P 500 Index when Republicans held the presidency, House and Senate for the one year after midterms was 15.1%. When Democrats have been in complete control, the increase averaged 9.3%."
Many analysts (including myself) believe that Trump is going to scale back tariff talks before mid-terms in November. This will allow markets to reach new highs. Despite what I hear from many analyst here, it's Trump keeping this market from hitting new highs, and it will be his policy stance that will allow us to break through this consolidation period.
Don't get me wrong, the Fed, inflation, the yield curve, etc. will be concerns, just not much in 2018 (likely 2019 as well).
Proprietary models that I follow suggest that S&P 500 will reach ATHs this year - see red line.
SPXL or UPRO (3x leveraged index funds) are one of the best ways to play this rally.
I'd be a buyer on dips.
Cheers!
