"Today's retail sales and consumer confidence data fall into the argument of those who believe the Fed lift-off date may come sooner," Mark Luschini, chief investment strategist at Philadelphia-based Janney Montgomery Scott, which oversees $67 billion in assets, said by phone. "The worry is if the Fed has to lift rates sooner rather than later, there's the question of when, but also what the trajectory of interest-rate increases will be and if it will undermine this sanguine picture of equities as the only game in town."
The 0.6 percent gain in retail sales matched the median forecast of 82 economists surveyed by Bloomberg and followed a 0.3 percent increase the prior month that was stronger than previously reported, Commerce Department figures showed on Friday in Washington. Eleven of 13 major categories showed advances, led by auto dealers and building material stores.
The Thomson Reuters/University of Michigan preliminary consumer sentiment index rose to 84.6 in September from 82.5 the month before. The median estimate in a Bloomberg survey of economists projected an increase to 83.3.

The S&P 500 decline this week on concern the Fed may raise interest rates sooner than forecast. The index closed at a record on Sept. 5, after rallying for five straight weeks, the longest winning streak this year.
