Here are some highlights from this past week's earnings coverage on BloggingStocks:

• ADC Telecommunications Inc. (ADCT) posted a surprise net loss for Q4 and predicted a loss in Q1.
• BJ's Wholesale Club Inc. (BJ) shares fell after Q3 earnings met expectations and offered guidance for FY.
• Dell Inc. (DELL) posted lower-than-expected Q3 earnings, prompting a sell-off of shares.
• Foot Locker Inc. (FL) said Q3 earnings slumped more than analysts' forecast, sending shares lower.
• Gap Inc. (GPS) reported growth of EPS and revenue in Q3 and announced a share buyback program.

BJ's Wholesale Club (BJ), whose competitive colleagues include Costco Wholesale Corporation (COST) and Wal-Mart Stores, Inc. (WMT), issued Q3 results earlier today. According to TheStreet.com, adjusted earnings of 45 cents per share met expectations.

And apparently that wasn't good enough for the traders. As of this writing, shares of BJ's were trading down 3% on above-average volume. Was the BJ's story that bad?

BJ's Wholesale Club (NYSE: BJ - option chain) stock is trading lower today after the company reported its same-store sales slipped 0.5 percent in September. Analysts were expecting a 1 percent decline, but traders saw competitor, Costco (NASDAQ: COST) post a 1% rise in September same-store sales and wanted more from BJ. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on BJ.

This morning, BJ opened at $35.90. So far today the stock has hit a high of $36.13 and a low of $35.90. As of 11:20, BJ is trading at $36.10, down 96 cents (-2.6%). The chart for BJ looks bullish and S&P gives BJ a positive 4 STARS (out of 5) buy ranking.

Costco Wholesale Corp. (NASDAQ: COST), the popular warehouse store that competes with BJ's Wholesale Club (NYSE: BJ) and Wal-Mart (NYSE: WMT), will report Q4 earnings on Wednesday, October 7. How will the company do?

Don't look for growth, my friends. According to Earnings.com, estimates from Wall Street say that Costco will produce 77 cents per share in income. Unfortunately, that represents a 16% drop in the metric. Surprising? Maybe a little. After all, we're still suffering a bad economy, and you figure that people would want to cut costs by leveraging the bulk buying power of the Costco business model.

Albert Gonzalez faced the music in a U.S. District Court in Boston on Friday, pleading guilty to masterminding one of the biggest cases of identity theft in history. The deal he struck with prosecutors could have him turning big rocks into little ones for up to a quarter of a century.

The Miami resident compromised the computer systems of large, high-profile retailers, including TJX (NYSE: TJX), BJ's Wholesale Club (NYSE: BJ), OfficeMax (NYSE: OMX), Barnes & Noble (NYSE: BKS) and Sports Authority. Tens of millions of credit card numbers were swiped in this scheme, leading to 19 counts of conspiracy, computer fraud, wire fraud, access device fraud and aggravated identity theft -- if there are other charges ... well, you get the point.

In a distinctly depressing sign of the times, BJ's Wholesale Club, Inc. (NYSE: BJ) announced today that it will begin accepting food stamps as payment at all 180 of its retail locations. Food-stamp payments will be processed through the Electronic Benefit Transfer (EBT) system.

"BJ's recognizes the diverse financial status and changing needs of its members," commented president and CEO Laura Sen in a statement.

Costco (NASDAQ: COST), a warehouse club that competes with BJ's Wholesale Club (NYSE: BJ) and Wal-Mart (NYSE: WMT), reported earnings for the second quarter on Wednesday. The company experienced a significant drop in the bottom line. Costco earned 54 cents per share on a diluted basis. That represented a decline of 26%. Analysts thought that 59 cents per share was doable. It wasn't. Net sales dropped 1%. Excluding gasoline and currency effects, same-store sales went up by 5% overall during the quarter (including those items, comps declined 3%).

Well, now, what does this tell us about Costco? It tells us that the whole thesis that people will be looking to save money by shopping at warehouse clubs doesn't necessarily translate into a successful earnings picture. Hey, what can you do? We're in a grand recession. And it's getting worse. Of course, it should be noted that Costco management must strive to work even harder to get people to spend more money in their stores. In fact, BJ's did pretty well with its numbers: Costco's competitor beat the analysts, even after adjustments.

While the release of economic data doesn't stop next week (see economic schedule highlights below), the earnings season does wind down dramatically.

About the only companies of note expected by analysts surveyed by Thomson Reuters to report falling earnings this week are Costco Wholesale Corp. (NASDAQ: COST), Wendy's/Arby's Group Inc. (NYSE: WEN), Foot Locker Inc. (NYSE: FL), Bank of Montreal (NYSE: BMO), and Steinway Musical Instruments Inc. (NYSE: LVB).

While PetSmart Inc. (NASDAQ: PETM) and Big Lots Inc. (NYSE: BIG) quarterly profits are expected to be about the same as a year ago, Liz Claiborne Inc. (NYSE: LIZ), Kenneth Cole Productions Inc.
