Eastern time, the S&P 500 was 0.1% higher, the Dow Jones Industrial Average was down 0.2%, and the Nasdaq Composite was up 0.2%

Just a day after the S&P 500 and Nasdaq hit record territory, both indexes climbed to fresh highs once again on Friday, though weakness in American Express (AXP) has weighed on the Dow, leaving markets muted.

But for Wall Street, it's been a heavy week. Both the S&P 500 and the Dow are on track for only modest gains as investors waded through a maze of mixed signals - robust retail sales, a rise in consumer inflation, and flat producer prices for June.
