Markets opened lower this morning, with the DJIA down around 70 points before noon as it pulled back from near 12,000. Earnings reports from some blue-chip stocks were lukewarm to poor, contributing to the slide. News that President Obama will propose a federal spending freeze and a ban on congressional earmarks provided a bit of an up-tick in the early afternoon, but not enough to overcome the earlier decline. Crude oil is trading below $87/barrel and gold is down -$13/oz, to $1,331.50, its lowest level in nearly three months.

Dow Jones 11,977.19 -3.33 (-0.03%)
S&P 500 1,291.18 +0.34 (0.03%)

"Booming Internet usage is creating unprecedented global demand for wireless data service; and mobile data usage is the fastest-growing segment of the communications market worldwide," says Keith Fitz-Gerald.

The editor of The Money Map Report explains, "My experience tells me that we are witnessing the early stages of what is rapidly becoming a self-sustaining cycle that's a long way from saturation. One beneficiary of this trend is our latest featured stock, Tellabs (TLAB),

"What's really putting this trend front and center is the growth in what's called "converged devices." These are things like smart printers, Skype-enabled PDAs, embedded laptops, and machine-to-machine devices.

Today's gains were wiped out in the afternoon after the weakening Euro again spooked investors. The Fed's Beige Book also was 'steady as she goes' but did contain the note that inventory investing from companies was declining, and that showed some added concern that businesses weren't as optimistic as some may have hoped. The real closing bell was yet another day where the verdict of an up-day or down-day was not certain until the very end.

Here were today's unofficial closing bell levels:

Dow 9,899.25 -40.73 (-0.41%)
S&P 500 1,055.65 -6.35 (-0.60%)
Nasdaq 2,158.85 -11.72 (-0.54%)

Another blown day.... Something that is becoming all too frequent. A low volume day followed by an obvious lack of buyers is also adding to the notion that stocks will continue to weaken. We started out weak, then tried to rally, but the bears won today.

Here were today's unofficial closing bell levels:

Dow 9,816.49 -115.48 (-1.16%)
S&P 500 1,050.47 -14.41 (-1.35%)
Nasdaq 2,173.90 -45.27 (-2.04%)

Stronger than expected consumer confidence results didn't matter to traders today. Concerns about Greece and other PIIGS nations dominated the market after S&P cut Portugal's debt ratings. Testimony from Goldman Sachs in Washington D.C. captured almost all of the day's media attention. The closing bell also came in effectively at the lows of the trading day.

Here were the unofficial closing bell levels:

Dow 10,991.99 -213.04 (-1.90%)
Nasdaq 2,471.47 -51.48 (-2.04%)
S&P 500 1,183.71 -28.34 (-2.34%)

The stock market was a roller-coaster today, and suddenly over the last week and a half we have gone from a market where volatility was very low to one where triple-digit DJIA point moves occur and get reversed in almost the same day. The VIX even opened right over 26.0 today before selling off. We started the day mixed, then went very positive, and then went very negative toward the end of the day. Earnings are still strong, but valuations are weighing on investors as you see many names selling off even after good earnings. The wide budget deficit only highlights more and more long-term concerns.

Here were the unofficial closing bell levels:

Dow 10,200.19 +3.33 (0.03%)
S&P 500 1,092.17 -4.61 (-0.42%)
Nasdaq 2,203.73 -7.07 (-0.32%)

"If you are looking for maximum rebound potential, you have to go lower down on the quality spectrum; it is typically the lower quality and lower priced stocks that will have the largest gains when the market rebounds," says turnaround expert George Putnam.

In his industry-leading service focused on distressed companies, The Turnround Letter, he looks at a package of 10 stocks recently trading below $5 per share while also offering "bundles of cash."

Here's his review:

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.

Among telecom stocks that got smacked during the past decade, Ciena Corporation (NASDAQ: CIEN) took the hardest hit -- at least, among those companies that still exist in the same incarnation. Yes, that comment was directed at you, Alcatel-Lucent (NYSE: ALU).

Other telecom losers on our roster include Qwest Communications (NYSE: Q), JDS Uniphase (NASDAQ: JDSU), and Tellabs, Inc. (NASDAQ: TLAB) -- the latter of which also plays a key role in the forthcoming Ciena saga.

What went wrong? At number 3 on our list of SPX laggards, CIEN lost 90% of its value in the decade that ended June 30, 2008. The stock peaked at a split-adjusted $1,057 in October 2000, a zenith that marked the top of a steep ascent. The equity's ensuing plunge would be just as dramatic.

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.

MOST NOTEWORTHY: Nike Inc (NYSE: NKE), Foot Locker Inc (NYSE: FL), Tellabs Inc (NASDAQ: TLAB), ADTRAN, Inc (NASDAQ: ADTN) and Bookham, Inc (NASDAQ: BKHM) were today's noteworthy downgrades:

• Banc of America downgraded shares of both Nike and Foot Locker to Neutral from Buy, as the firm believes industry pressures in the U.S. could more than offset the potential turn in Europe and benefit from the 2008 Olympics.
• Cowen downgraded shares of ADTRAN, Bookham and Tellabs to Neutral from Outperform.
• Goldman Sachs also downgraded shares of Tellabs, to Sell from Neutral, as the firm believes the stock fully discounts the expected sales and margin improvement.

OTHER DOWNGRADES:

• Allergan Inc (NYSE: AGN) was downgraded to Equal Weight from Overweight at Morgan Stanley citing limited upside.
• Friedman Billings removed The Cheesecake Factory Incorporated (NASDAQ: CAKE) from its Top Picks and maintained its Outperform rating.
• Lehman downgraded shares of The First American Corporation (NYSE: FAF) to Equal-Weight from Overweight on increasing risk to the company's title margin and regulatory concerns.
• Matrix USA downgraded shares of Lowe's Companies Inc (NYSE: LOW) to Buy from Strong Buy on valuation.
