S&P 500 Signals More Gains in Crossing 100-Day Threshold

Gains through year-end are pretty much a lock for U.S. stocks, assuming history is any guide. This year marked the 41st time since 1928 in which the S&P 500 Index started the last 100 days of trading up at least 6 percent for the year, according to data compiled by Ryan Detrick, a senior market strategist at LPL Financial Research. In previous years, the index moved higher through year-end 90 percent of the time, including the 10 most recent occurrences. This year’s period began on Wednesday, when the S&P 500 slid 0.3 percent.
