US stock market closes mixed

By Ovunc Kutlu

NEW YORK (AA) - The stock market closed mixed Monday on a shaky day for retail stocks.

With Amazon's once-a-year Prime Day just hours away, investors took the opportunity to focus on the e-commerce.

At the final bell, the company’s shares were up 1.8 percent, before its 30-hour long Prime Day kicks off at 9 p.m. EST (0100GMT) that will provide discounts on thousands of products.

Other major retailers, however, including Costco and Walmart, saw their shares decline 2 percent and 2.8 percent, respectively.

As a result, the Dow closed flat, down 5 points to 21,408.

The S&P added 2 points to end the day at 2,427 and the Nasdaq increased 23 points to finish at 6,176.
