When Amazon announced last week that it will acquire Whole Foods Market, a grocery chain with over 450 retail stores and deep industry talent, for $13.7 billion, Amazon’s stock price rose 2.4% on the news, increasing its market capitalization by $11 billion. At the same time, the price of SuperValu plummeted 14.4%, Kroger dropped 9.2%, and Sprouts fell 6.3%. You could almost hear the three-year plans of every grocer, and nearly every other traditional retailer, grinding through the shredding machines.
