Producer prices gained 0.3 percent in July, the fastest pace in five months in July, according to the Labor Department. Analysts polled by Reuters expected the index to rise 0.2 percent.

Michael Kors soared after the upscale apparel retailer posted better-than-expected earnings and raised its full-year earnings forecast.
TJX raised its full-year earnings forecast on a rise in its quarterly revenue, thanks to shoppers seeing discounted designer products.
Meanwhile, department-store chain Saks posted a narrower-than-expected quarterly loss and maintained its revenue forecast for the second half of the fiscal year.
