TheStreet.com's Jim Cramer says if the company you're looking at is a player in the mobile Internet space, it's probably a good bet.

Does it have smartphone exposure, or doesn't it? That is the question. When I look at what's moving in tech and what's become sullen and gloomy, there's only one compass: smartphones. Think about what's moved this week: Cree (NASDAQ: CREE) (Cramer's Take), Tellabs (NASDAQ: TLAB) (Cramer's Take) and ADC Telecom (NASDAQ: ADCT) (Cramer's Take). These are terrific plays in the smartphone food chain and are included in the "Mad Money" Mobile Internet Index.

ADC Telecom is Chinese Internet infrastructure, and we know that China's spending $40 billion to build out infrastructure that can allow aggressive adoption of smartphones. Tellabs has been waiting for next-generation telecom orders -- smartphones. I think the fact that it announced a giant buyback -- it matters when the stock is this small -- is the signal needed to suggest they are getting orders.

"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:

Stocks were wishy-washy all day long, but had a very late-day comeback from earlier lows. Stocks were lower overseas as it turned out that the Madoff-fraud losses were actually going to cost some real companies some real money. The housing data left little to be desired for the six months ahead. The "whatever the bailout plan from the White House for the auto sector" was also another uncertainty today.

Here are today's unofficial closing bell levels:
DJIA: 8,564.53 -65.15 -0.75%
NASDAQ: 1,508.34 -32.38 -2.10%
S&P 500: 868.60 -11.13 -1.27%

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.

Whether it's building a distribution system that lets your cable company transmit voice-video-data, or providing the systems that enable your phone company to build its fiber optic backbone network, there is an outfit in Naperville, Illinois that has the breadth of experience to make the process a smooth one.

Tellabs Inc. (NASDAQ: TLAB) designs, develops and deploys telecommunications networking products. Its portfolio includes systems for wireline and wireless transport, access networking, broadband data, optical transport, and voice-quality enhancement. Clients include cable operators, corporations, government agencies and such carriers as Verizon Communications (NYSE: VZ), AT&T (NYSE: T) and Sprint Nextel (NYSE: S). Alcatel-Lucent (NYSE: ALU), Cisco Systems (NASDAQ: CSCO) and Nortel Networks (NYSE: NT) are major competitors.

The company pleased investors last week, when it reported Q1 EPS of six cents and revenues of $452 million. Analysts, who said the company saw strong demand for its advanced phone switching gear, had been expecting five cents and $452 million. Management also guided Q2 revenues to $500-$520 million, versus Street consensus of $502.5 million. The CEO said the firm was encouraged that its new technologies are "taking root" in service provider networks. TLAB shares popped into a bullish "flag" consolidation pattern on the news. Prices frequently exit flags moving in the same direction they were traveling when they entered them. For TLAB, that break out commenced today.

Brokers recommend the issue with three "strong buys," three "buys," 12 "holds" and five "sells." Analysts see a 42% growth rate, through the next year. The TLAB Price to Sales ratio (2.39), Price to Book ratio (1.60), Price to Cash Flow ratio (15.90) and Price to Free Cash Flow ratio (17.46) compare favorably with industry, sector and S&P 500 averages.

Institutional investors hold about 70% of the outstanding shares. The stock is one of those used to calculate the S&P 500 Index and the Nasdaq 100 Index. Over the past 52 weeks, it has traded between $8.84 and $16.40. A stop-loss of $9.55 looks good here.

Jim Cramer also came out on CNBC's MAD MONEY with some speculative stocks in telecom, even though his main focus in telecom is defensive right now. He said that the telecom expense expansions are back on track and these are his two speculative plays:

Tellabs Inc. (NASDAQ: TLAB) is the spending play for AT&T's U-verse roll-out. He likes its "last-mile technology" for broadband and terminals. Ciena Corp. (NASDAQ: CIEN) is the spending play for Verizon's FiOS roll-out. Cramer also recommended taking profits on these as the contracts roll in. Cramer even said that Alcatel-Lucent (NYSE:ALU) may need to make an acquisition after its horrible quarter, and either stock would fit the bill.

While it is easy to just believe the telecom expansion is underway, you should be aware that the speculation around this has been underway for close to a year. These stocks also have long histories and time has shown that you can't stay too long in the recoveries. Before getting too excited about these picks as fresh, Cramer did come out with these just yesterday already and has been making positive comments on them in recent days. So his fresh calls aren't really that fresh tonight. Regardless of whatever these stocks do, please be aware that under no circumstances are these "defensive" portfolio plays. Most of these telecom equipment and optic roll-out plays have been boom and bust and back again. These have been the 'Boulevard of Broken Dreams' and the 'Field of Dreams,' so pick your poison carefully.

CIENA Corp. (NASDAQ: CIEN) opened at $30.95. So far today the stock has hit a low of $30.14 and a high of $30.95. As of 11:00, CIEN is trading at $30.18, down $0.01 (-0.1%).

After hitting a one year high of $33.67 in June, the stock has been volatile all year, hitting a year low of $22.04 in November. Jim Cramer wrote today that Verizon's (NYSE: VZ) earnings release this morning indicates that spending on optical businesses is going to see a notable jump for the first time in ages. Though he hates this sector, which he says hinges solely on Verizon, he thinks now is the time to get in. With Verizon's earnings out of the way, stocks like Ciena, Corning (NYSE: GLW), JDSU (NASDAQ: JDSU), and Tellabs (NASDAQ: TLAB) stand to benefit from the spending cycle. Recent technical indicators for CIEN have been bullish and steady, while S&P gives the stock a neutral 3 STARS (out of 5) hold rating.

For a bullish hedged play on this stock, I would consider a July bull-put credit spread below the $25 range. CIEN hasn't been below $25 since November and has shown support around $27.80 recently. This trade could be risky if Q2 earnings (due out in late May or early June) disappoint, but even if that happens, this position could be protected by the historical support around $25.
