Saks Fifth Avenue (NYSE: SKS) is the latest retailer to let down investors after posting disappointing quarterly results. The upscale department store operator reported a second-quarter loss that was wider than Wall Street expected, as costs mounted and sales faltered. However, Saks didn't blame its shortcomings on the consumer like so many other retailers did.

Trending down
Sales rose a meager 0.5% to $707.8 million for Saks' last quarter as a publicly traded company. Analysts were looking for revenue of $732.3 million. This translated into a loss of $19.6 million or $0.13 per share, compared to a loss of $12.3 million or $0.08 a share in the year-ago period  However, excluding certain charges such as $2.5 million in costs related to the retailer's pending merger with Canadian-based Hudson's Bay, the per-share loss would be $0.10.

While other department store chains including Macy's (M -2.68%) and Nordstrom (JWN 0.96%) blamed weak sales on the consumer, Saks held itself accountable. Saks said higher year-over-year markdowns of men's and women's shoes hurt margins in the quarter, while sales were negatively affected by a late start to the company's annual end-of-spring sales event.

Let's see how Saks' second-quarter earnings measure up to rival department store stocks.

Ouch. It wasn't a flattering second quarter for any of these department stores. In fact, both Macy's and Nordstrom reduced their full-year outlooks due to the challenging retail environment. Macy's now expects same-store sales growth of between 2% and 2.9% for fiscal 2013, down from 3.5%. Meanwhile, Nordstrom now expects comps to increase just 2% to 3% on the year, below its previous prediction of 3% to 5% growth.

Saks, on the other hand, didn't provide guidance since it agreed to be purchased by Hudson's Bay for $16 a share last month. The deal, which is valued at $2.9 billion including debt, is expected to close before the end of the year, according to Saks.

It has been a tough earnings season for retail stocks.
