 "Wall Street dips as Amazon-Whole Foods deal slams retailers")
US stocks dipped on Friday as shares of Wal-Mart and other retailers were hammered after Amazon.com announced its entry into the brick-and-mortar retail business with its $13.7 billion deal to buy upscale grocer Whole Foods.
The deal rattled the retail sector. The S&P 500 consumer staples index dropped 1.14 percent, weighed down by Wal-Mart, Costco and Kroger.
Wal-Mart, which also announced a deal to buy online clothing retailer Bonobos for $310 million, dropped 5 percent and weighed the most on the S&P 500 and the Dow.
Amazon shares were up 3.4 percent at $997.84, while Whole Foods surged 27.7 percent.
"Amazon's got its tentacles everywhere and that's another place to go," said Bruce Bittles, chief investment strategist at R.W. Baird & Co.
"Amazon sees that industry changing significantly - and they see that people don't necessary go to the grocery store anymore."
