Macy's posted a 5.2% fall in same-store sales year-over-year, J.C. Penney reported a narrower-than-expected quarterly loss, but revenue missed estimates. Nordstrom topped earnings estimates on both the top and bottom lines, but same-store sales declined. Kohl's posted a rise in year-over-year quarterly profit but same-store sales dropped.
TheStreet breaks down 10 things we learned from this week's shows with Jim Cramer.
1. J.C. Penney vs. Amazon
J.C. Penney's home furnishings merchandise could be hurt by Amazon's push into the furniture space, according to Cramer.
"When you see a Penney, you say to yourself, why does it need to exist?" Cramer pondered, adding that the Sephora kiosks are a positive part of the J.C. Penney picture.
2. Nordstrom vs. Amazon
"Right now Nordstrom is doing not that horrible, but their stock is reflecting that it will do worse," Cramer said. Nordstrom shares are down 13% since the start of the year.
3. Macy's Is Very Challenged
"Macy's is very challenged," Cramer said. "The stores look terrible." Cramer said the stock may be bottoming, but it's unclear how much upside there is.
