Experienced investors know that in the frugal consumer era, one should move cautiously regarding restaurant plays, due to sector consolidation.

Restaurant chain Darden Restaurants (DRI), first discussed on June 25, 2009, at a price of $32.78, will likely be among the sector's survivors. Here's why.

TheStreet.com's Jim Cramer says a good shakeout on Monday would prepare us for a "fulcrum day" on Tuesday.

Could have been worse. With Research In Motion (NASDAQ: RIMM) (Cramer's Take) never lifting -- which was, by the way, wrong after a certain point -- and oil not rallying, you had no place to go. Last week we lost tech, banks, and oil. You can't even go up with just two of them, so to lose all three was dreadful.

I said last week that the calendar just didn't favor the bulls. The propensity to want to lock in gains ahead of the last weekend in September -- the one that is ended by the Yom Kippur holiday, which will always have thin trading -- is just too great.

Plus, don't forget that every month that is supposed to be bad gets tons of play for being bad: October! Ooooooo, scary! You know that's going to happen again.

Autumn has arrived and the quarter winds down this week. The Dow has been inching toward 10,000 for a while now, though it closed lower in the past three sessions. Can it make it to 10,000 for the start of the third quarter? If so, what will push it higher? If not, what will drag it down further?

• Monday is Yom Kippur, the most solemn of the Jewish holidays; trading likely will be lighter than usual. In the evening, the FDIC meets to discuss how to rebuild the Bank Deposit Insurance Fund.
• Tuesday, the Consumer Confidence Index for September is due and the SEC holds a public meeting to consider more short sale actions.

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

• Accenture Ltd. (NYSE: ACN) beat earnings expectations but revenue was hurt by currency effects.
• Bed Bath & Beyond Inc. (NASDAQ: BBBY) strong Q1 results beat estimates but same-store sales fell.
• CKE Restaurants Inc. (NYSE: CKR) lower Q1 earnings and strong sales both topped expectations.
• ConAgra Foods Inc. (NYSE: CAG) higher Q4 earnings were in line with expectations, and shares slipped.
• Darden Restaurants Inc. (NYSE: DRI) Q4 results were higher, but it warned of continuing challenges.
• Hennes & Mauritz (OTC: HMRZF) reported strong Q2 numbers, though same-stores sales slipped.

This week brings a small flurry of end-of-the-calendar-quarter earnings reports. And for the most part, the expectations of the analysts surveyed by Thomson Reuters aren't very high. Companies expected to report declining earnings in the most recently concluded quarter include America's Car-Mart Inc. (NASDAQ: CRMT), Bed Bath & Beyond Inc. (NASDAQ: BBBY), ConAgra Foods Inc. (NYSE: CAG), Jabil Circuit Inc. (NYSE: JBL), Jackson Hewitt Tax Service Inc. (NYSE: JTX), Monsanto Co. (NYSE: MON), and Sonic Corp. (NASDAQ: SONC).

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

• Blockbuster Inc. (NYSE: BBI) crushed analyst's expectations for Q4 as same-store sales rose.
