U.S. stocks slipped Friday after equities suffered their worst percentage drop in two weeks, with the S&P 500 on track for its first decline in the past six weeks.
The S&P lost 0.7 percent on Thursday, its biggest percentage drop since March 6. The benchmark index is still near four-year highs.
The benchmark S&P is down 0.8 percent for the week, and many investors were waiting for a further pullback as the index has risen 10.8 percent for the year and 26.7 percent from its October low.
Indexes could get a boost next week from quarter-end "window dressing" as fund managers drop poor performing stocks and chase better-performing ones.
Factory data showing a slowdown in both the euro zone and China sent the S&P 500 lower on Thursday to its first close closed below 1,400 in six sessions.
"Today investors are basically going to focus on the domestic economy, so new home sales could re-energize the upward trend," said Peter Cardillo, chief market economist at Rockwell Global Capital in New York.
