But Boss warned that the lower-end consumer is still in a "fragile" state: "Further down the spectrum, at the low-end … I think you're seeing a much greater pressure than you are as you trend toward the high-end."
To capitalize on that, Boss said he likes Saks in the luxury department store space because it's addressing the integration of online and in-store inventory in what could be a "powerful" way. "At the same time, they've revamped the credit rewards," he said.
"Saks also has the highest correlation to the wealth-effect," he explained, adding that the retailer would benefit greatly if the Dow Jones Industrial Average and the S&P 500 continued higher in the "back half of the year."
In the mid-tier, a company like Macy's, Boss argued, has been successful at "broadening the customer base" — not relying on only one type of consumer. "If you walked to a Macy's tomorrow you'd see a low-end, a middle income, as well as a higher-income shopper," he said.
Another factor benefiting Macy's is "[the] J.C. Penney disruption — over $3 billion in revenues lost," he observed. "I think they have a long and tough road ahead."
But Boss doesn't think J.C. Penney will file for bankruptcy protection or become a takeover target. "The reality is this turnaround is going to take a lot longer than the CEO [Ron Johnson] initially thought," he said.

As for the future, he concluded that J.C. Penney won't go back to the old strategy of heavy discounting, but operate under a "somewhat promotional" model. "They're trying to upscale some of their merchandise, and do the best in terms of driving traffic back into the stores," he said.
