With falling trade tensions, the U.S. Federal Reserve clearly committed to holding rates steady, and solid, if not spectacular, economic data, U.S. stock markets have settled into a pattern of relative calm. The S&P 500 has closed less than 1% higher, or lower, for 70 consecutive trading sessions, the longest streak without such a move since a 74-day run that ended on Oct. 9, 2018. A move of less than 1% as of Monday’s close would extend the calm spell to 71 sessions, but as of mid morning, that appeared unlikely.
