A number of Wall Street research firms are out defending stocks that fell yesterday after Amazon (AMZN) announced that it would cut prices at Whole Foods (WFM) stores as soon as its deal to buy the grocer closes this Monday. UBS wrote that the decline in the shares of Costco (COST) and Spouts Farmers (SFM) was “a bit” overdone, while SunTrust contended that Spouts and another supermarket chain, Kroger (KR), would probably not be hurt much by Amazon’s move.

UBS: Nearly 49% of Sprouts Farmers’ stores are located within a ten-minute drive of at least one Whole Foods store, noted UBS analyst Michael Lasser. Although Whole Foods’ price cuts “could be a slight headwind” to Sprouts “over time,” the company’s unique produce pricing strategy and sourcing should help insulate it from the long term threat better than most, Lasser believes. About 33% of Costco’s stores are within a ten-minute drive of a Whole Foods, but over half of Costco’s revenue is generated from “conventional groceries and gas,” according to Lasser. As a result, the analyst believes that Costco’s products are “complementary” with those of Amazon, giving Costco members “plenty of incentive” to renew their membership with the discount retail giant.

SUNTRUST: Analyst David Magee says he doesn’t expect Kroger (KR) and Sprouts to be significantly hurt by the move in the near-term. Calling Kroger’s customer base distinct from that of Whole Foods, Magee says that only 10% of Kroger’s stores are within three miles of a Whole Foods. That situation shouldn’t change much, since both companies are growing their stores at “methodical” rates, he added. Furthermore, he says that 85%-90% of Kroger’s products are “conventional,” differentiating it from Whole Foods. Sprout’s outlook is tied much more to “the broader pricing environment,” while its current initiatives, including its private label offering and the expansion of its deli counters, are gaining traction, Magee stated.
