By MARLEY JAYNEW YORK (AP) — U.S. stocks are slightly lower Friday as Amazon's $13.4 billion deal for Whole Foods Market is sending grocery stores, big retailers, and food makers and distributors plunging. Amazon and Whole Foods are both climbing. The rest of the market is little changed. Energy companies are rising as the price of oil moves higher. KEEPING SCORE: The Standard & Poor's 500 index lost 1 point, or 0.1 percent, to 2,430 as of 3 p.m. Eastern time. The Dow Jones industrial average edged up 9 points to 21,368. The Nasdaq composite fell 11 points, or 0.2 percent, to 6,154. The Russell 2000 index of smaller company stocks shed 7 points, or 0.5 percent, to 1,402. GROCERY SHOPPING: Online juggernaut Amazon said it will buy organic grocery company Whole Foods Market for about $13.4 billion, or $42 a share. Whole Foods had been the target of sale rumors for two months and investors appeared to wonder if another bidder might try to buy it. Whole Foods jumped $9.96, or 30.1 percent, to a two-year high of $43.02. Amazon climbed $34.62, or 3.6 percent, to $998.79, its biggest gain of the year. Amazon already runs AmazonFresh, a grocery delivery service that costs $14.99 a month for members of its Prime delivery service, and it recently opened a few grocery stores. Many investors suspected it would eventually make a bigger move into that business. THE QUOTE: It's rare for a single deal to have a big effect on the broader stock market, but the deal between Amazon and Whole Foods did. Neil Saunders, managing director of the research firm Global Data Retail, said Amazon is likely to push companies that sell food to lower their prices, which will affect the companies that make and distribute those products.
