I'm reiterating my Buy rating for Ciena Corp. (NASDAQ: CIEN), first recommended on May 19, 2009, at a price of $11.27.

Given the likely U.S. recovery, increased demand for bandwidth in the quarters/years ahead will more than offset any near-term sales weakness, which is good news for bandwidth provider Ciena.

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

• Abercrombie & Fitch Co. (NYSE: ANF) earnings prospects and declining sales resulted in a downgrade.
• America's Car-Mart Inc. (NASDAQ: CRMT) stronger-than-expected Q1 results led shares to a four-year high.
• ArcSight Inc. (NASDAQ: ARST) reported strong Q1 numbers on increasing demand for cyber security.
• Brown-Forman Inc. (NYSE: BF.B) Q1 results easily topped expectations despite a decline in revenue.
• Ciena Corp. (NASDAQ: CIEN) posted a Q3 loss but revenue improved sequentially, and shares rose.

Just a couple years ago, the shares of Ciena Corp. (NASDAQ: CIEN) were above $40. But since then, it's been brutal -- with the shares eventually falling to $5.35. After all, the company is in the competitive telecom-equipment space.

However, things have been getting better lately. In fact, the share price is now at $13.06.

And this week Ciena reported its fiscal Q3 earnings report. While revenues dropped 35% over the past year, they were actually up 14% over the prior quarter. There was a net loss of $26.5 million, or $0.29 per share.

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

• Aetna Inc. (NYSE: AET) lowered its 2009 earnings guidance, initially sending the share price lower.
• Ciena Corp. (NASDAQ: CIEN) reported a bigger-than-expected Q2 net loss as revenues sank.
• Collective Brands Inc. (NYSE: PSS) saw Q1 earnings and sales decline, but beat Wall Street estimates.
• Google Inc. (NASDAQ: GOOG) earnings prospects led Goldman Sachs analysts to increase its forecasts.
• Guess? Inc. (NYSE: GES) weak Q1 results topped estimates and it offered guidance that pleased investors.

Ciena (NASDAQ: CIEN), a business that sells various networking and software products for fiber-optic and broadband technologies, and whose colleagues include Cisco (NASDAQ: CSCO) and Alcatel-Lucent (NYSE: ALU), reported late Thursday a difficult second quarter. Revenues declined by 40%. For the bottom line, Ciena said it lost 25 cents per share on an adjusted basis. Last year at this time, Ciena made an adjusted 40 cents per share. And in terms of expectations, the company was only supposed to lose 9 cents per share. Guess there wasn't a chance of that, huh?

Much of the attention this week will no doubt be on how the impending General Motors (NYSE: GM) bankruptcy will shake out, as well as the usual economic concerns: Has the housing market bottomed? Will oil prices keep rising? Is the employment situation getting any better? And so on (see highlights of the economic calendar below).

What probably won't get much attention are quarterly earnings, as the earnings season for this quarter winds down. But there are a few reports that analysts surveyed by Thomson Reuters have high hopes for.

The U.S. recession has hit just about every sector fairly hard, save health care; internet services have certainly not been immune.

Still, Wall Street has been known to overdo it somewhat on the downside, particularly when a growth play runs into a recession, and that's why Ciena Corp. (NASDAQ: CIEN) is worth a review.

Ciena supplies communications networking equipment, software and services to communications service providers, cable operators, governments and enterprises. The company specializes in helping organizations transition from old-world architectures to high-bandwidth services. Hence, CIEN is largely a broadband play, and now that it looks like better days are up ahead for the U.S. economy in a quarter or two, firms will begin to make the investments they need to stay competitive in a decidedly broadband world. The First Call F2009/F2010 EPS estimates for CIEN are a loss of 21 cents and a profit of 15 cents.

While the release of economic data doesn't stop next week (see economic schedule highlights below), the earnings season does wind down dramatically. Most of the S&P 500 companies already have reported on the past quarter, which means dismal earnings news is largely behind us, at least for a while. 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. (NYSE: KCP), Ciena Corp. (NASDAQ: CIEN), and Trina Solar Ltd. (NYSE: TSL) are expected to have swung to losses in the most recent quarter.

Even as the holiday season ramps up and the calendar quarter begins to wind down, earnings reports continue to dribble in. Among the companies scheduled to release quarterly results this coming week, analysts surveyed by Thomson Reuters are expecting BWAY Holding Co. (NYSE: BWY), Powell Industries Inc. (NASDAQ: POWL), and Esterline Technologies Corp. (NYSE: ESL) to be among the biggest earnings gainers.

Atlanta-based packaging and container producer BWAY is expected to report fiscal fourth-quarter profits that are 65.6% higher than in the same period of last year, or $0.32 per share on revenues of $265.2 million (+4.9%). BWAY topped estimates in the previous two quarters -- by 44.9% in the third quarter. Those results sent shares to a new 52-week high. But shares have fallen 62.7% in the past three months, and they are now trading near a multiyear low of $4.11 per share.

Houston-based energy equipment maker Powell is expected to report fiscal fourth-quarter profits that are 62.7% higher than a year ago, or $0.59 per share. Revenues are forecast to be 14.2% higher, or $171.8 million. Powell beat expectations in the past three quarters -- by 20.2% in the third quarter. The share price has fallen 47.7% in the past three months, and the consensus recommendation is to buy POWL.

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

• Boeing Co. (NYSE: BA) earnings prospects may have encouraged the machinist union to strike.
• Ciena Corp. (NASDAQ: CIEN) Q3 results and weak guidance led shares to a new 52-week low.
• Corning Inc. (NYSE: GLW) lowered its Q3 earnings guidance below previous and analysts' forecasts.

• New York Times Co. (NYSE: NYT) ongoing losses haven't diminished Rupert Murdoch's interest in it.
• Nokia Corp. (NYSE: NOK) warned that it would miss earnings estimates due in part to weak sales.
• Shanda Interactive Entertainment Ltd. (NASDAQ: SNDA) better-than-expected Q2 led to an analyst upgrade.
• Staples Inc. (NASDAQ: SPLS) Q2 earnings slipped while revenues rose, beating expectations.
• Take-Two Interactive Software Inc. (NASDAQ: TTWO) Q3 results soared but cut its Q4 guidance.
• Tenet Healthcare Corp. (NYSE: THC) was upgraded on its prospects for beating expectations.

• Tiffany & Co. (NYSE: TIF) posted better-than-expected Q2 results and offered full-year guidance.

While the earnings crunch for this quarter is all but over, there is still plenty of action in the earnings arena this coming week. For instance, analysts surveyed by Thomson Financial are expecting America's Car Mart Inc. (NASDAQ: CRMT) and Campbell Soup Co. (NYSE: CPB) to be among this week's top earnings gainers.

Bentonville, Ark.-based America's Car Mart is expected to post net income of 38 cents per share (up 52.6% from the same period a year ago) on revenue of $73.8 million (up 25.8%). The used car dealer chain has tended in recent quarters toward positive surprises -- by 21 cents per share, or 73.5%, in the previous quarter. The long-term EPS growth forecast is 15%, about the same as the S&P 500. The consensus recommendation of analysts is to buy CRMT.

Campell is tentatively scheduled to report this week, and the world's biggest soup maker is expected to post net income of 25 cents per share (up 44.0% from a year ago) on revenue of $1.7 billion (up 7.5%). The Camden, N.J.-based company has just missed earnings estimates in the past three quarters. Its long-term EPS growth forecast is 7.5%, which is less than the industry average, but about the same as rivals Kraft Foods (NYSE: KFT) and Heinz (NYSE: HNZ). The analysts' consensus recommendation is currently to buy Campbell.

Other anticipated double-digit earnings gainers scheduled to report this week include brand name apparel maker Guess Inc. (NYSE: GES), mining equipment maker Joy Global (NASDAQ: JOYG), and chip maker National Semiconductor (NYSE: NSM). And Take-Two Interactive Software (NASDAQ: TTWO) is expected to swing to a profit.

In this series, we take a look at the 25 stocks on the S&P 500 Index (SPX) that have turned in the worst performance during the past decade -- what went wrong, and what happens next.

Add Tellabs, Inc. (NASDAQ: TLAB) to the list of casualties from the Great Telecom Bust of the new millennium. It was a bloody massacre that highlighted the difficulties of forecasting; and, in particular, the danger of forecasting through the distorted lens of the dot-com bubble. When Internet traffic stopped multiplying at its previously exponential rate, the market was faced with a glut of supply and waning demand. Only the strong survived, but even they couldn't manage to thrive.

What went wrong? At No. 5 on our list of SPX underperformers, TLAB lost 87% of its value during the decade that ended June 30, 2008. The stock peaked at $77.25 in November 1999 before its momentum shifted.

In 1999, Tellabs was on an acquisition binge. A planned buyout of Ciena Corporation (NASDAQ: CIEN) had hit the skids, and the company made up for the loss by absorbing a series of smaller players -- within months, Tellabs told investors it would buy Alcatel's DSC Communications unit, Netcore Systems, and Salix Technologies.

• Bob Evans Farms Inc. (NASDAQ: BOBE) posted stronger-than-expected Q4 earnings.
• Ciena Corp. (NASDAQ: CIEN) beat earnings expectations, but share prices slipped anyway.
• Daktronics Inc. (NASDAQ: DAKT) Q4 results beat expectations and it raised its revenue outlook.
• Diageo (NYSE: DEO) is recession-proof and should deliver solid results, predicts one adviser.
• Donaldson Company Inc. (NYSE: DCI) beat Q3 expectations and raised its full-year guidance.
• Ensco International Inc. (NYSE: ESV) was upgraded because of its earnings growth potential.
• Lehman Brothers Holdings Inc. (NYSE: LEH) earnings prospects don't impress Jim Cramer.

• Wal-Mart Stores Inc. (NYSE: WMT) was upgraded due to its earnings outlook and increased productivity.

Also, continued real estate losses are expected to hurt the quarterly reports of banks such as like Wachovia (NYSE: WB), Wells Fargo (NYSE: WFC), and National City (NYSE: NCC). And Steven Mallas wonders why Playboy (NYSE: PLA) shares have tanked since its last earnings report.
