Both the S&P 500 and the Nasdaq hit a golden crossthis week—that's when the 50-day moving average crosses above the 200-day moving average. The golden cross is a signal the indices could move higher, according to technical strategists.
While the S&P 500 has posted impressive gains since the summer, Todd Salamone, senior vice president of research at Schaeffer's Investment Research, believes those gains can continue given the amount of money sitting on the sidelines.
"We like to see some evidence there is some sideline money that can at least confirm this golden cross will play out as expected, and/or push the S&P above its resistance levels," he said. "We think that’s available."
The Dow, meanwhile, continued to retreat after crossing through 11,205 during trading on Thursday. That was the highest close of the year, reached on April 26. The Dow is up 11.2 percent for September and October, on pace for its biggest percent gain since 1998.
