Seven retailers are particularly well-poised to endure Amazon.com’s (AMZN) growing dominance, according to Cowen Group.

Amazon sought to significantly broadened its retail reach Friday with a $13.7 billion bid to acquire Whole Foods Market (WFM), signaling an increasingly competitive environment for many retailers already struggling with same-store sales declines. But retailers in both discount/deep value and luxury niches are “un-Amazon-able,” says Cowen senior equity research analyst Oliver Chen. (See also: Top Retail Picks Right Now: Credit Suisse.)

Chen named seven “Super Stocks” as among those best positioned to endure the impact of Amazon's rapid growth: Costco Wholesale Corp. (COST), TJX Companies (TJX), Ross Stores Inc. (ROST), Wal-Mart Stores Inc. (WMT), Tiffany & Co. (TIF), LVMH Moet Hennessy Louis Vuitton and Sotheby's (BID).

"Taking a step back in the sector at large, we continue to believe investors will have more defense versus Amazon's domination if they follow our Super Stock theory. We think deep-value companies or luxury goods companies are more un-Amazon-able and less vulnerable to share losses versus Amazon,” Chen said in a recent note.

Discount retailers like Ross and TJ Maxx have been drawing more consumers since the recent recession. While Amazon’s takeover of Whole Foods will give it more market share in the grocery sector, Chen said wholesaler Costco’s notoriously low prices will continue to give it a distinct advantage there.

“Price leadership is a competitive advantage and important way to draw new and existing customers ... perhaps Costco does not really even need the digital bells and whistles if it can just offer the cheapest and best goods, services, and gas in the marketplace," Chen wrote. Costco can keep its prices lower because it owns some of its production facilities, Chen noted.

The SPDR S&P Retail ETF (XRT) is down 9.1 percent year to date, and down 3.3 percent the past year.
