Retail stocks rose Thursday, catching a lift from the broader market while analysts digested news that online retail giant Amazon.com Inc. (AMZN) said it agreed to buy Internet shoe and apparel store Zappos.com in a stock deal valued at $807 million.

Amazon said in a statement late Wednesday that it will buy all shares outstanding, warrants and options of Zappos in exchange for roughly 10 million Amazon shares with their value based on average closing prices in June and July. In addition, Amazon said it "will provide Zappos employees with $40 million in cash and restricted stock units."

With Amazon's scale and resources, its purchase of Zappos, which has sales of about $600 million to $700 million, may be "an incremental negative" for shoe retailers such as Foot Locker Inc. (FL) and Jones Apparel Group Inc. (JNY), a Credit Suisse report said. Jones operates Nine West and Easy Spirit stores.

"To the extent that Amazon.com can accelerate growth at Zappos by leveraging its existing customer base, we believe this acquisition will further erode market share at the undifferentiated mall-based boxes like Foot Locker, which in our view is an overstored concept in an overstored industry," the report said.

The report also said department stores such as Nordstrom Inc. (JWN), J.C. Penney Co. (JCP) and Macy's Inc. (M) also may be hurt as the purchase put Amazon on a "competitive collision course" with them.

"All of these are seeking to carve out significant Web presence," the report said. "The acquisition may well force all three department stores to spend incrementally on their Web business at a time when its profitability is generally under pressure."

Amazon.com shares jumped 5.5% in recent trading. Jones shares rose 5.3%. Foot Locker shares gained 2.6%. Nordstrom was up 4.6%. J.C. Penney was up 0.3%. Macy's rose 3.7%.

The S&P Retail Index (RLX) rose 0.9% to 343.24.

Investor sentiment also was bolstered by a wave of better-than-expected corporate earnings and better-than-forecast June existing home sales.
