• General Electric Co. (NYSE: GE) cut its Q4 earnings forecast, which now falls in line with estimates.
• Goldman Sachs Group Inc. (NYSE: GS) warned that it may see its first quarterly loss ever in Q4.
• Guess? Inc. (NYSE: GES) strong Q3 results beat estimates but offered a conservative outlook.
• Infineon Technologies AG (NYSE: IFX) posted a wider Q4 loss on restructuring and warned of further losses.
• Johnson & Johnson (NYSE: JNJ) 2009 earnings are expected to be diluted by an acquisition.
• Marvell Technology Group Ltd. (NASDAQ: MRVL) reported strong Q3 numbers, sending shares higher.
• Medicis Pharmaceutical Corp. (NYSE: MRX) earnings prospects after a settlement led to an analyst's upgrade.

Marvell Technology Group's (NASDAQ: MRVL) Q3 earnings report had some great numbers that made me want to consider the stock as a potential buy. However, some things about the long-term price action of the company's shares makes me want to avoid the stock altogether.

The bottom line for the storage and networking tech company increased 64% to $0.23 per diluted share; this number beat estimates by three pennies. Pretty cool, right? Here are a couple more positives: operational cash flow increased 41% on a sequential basis compared to Q2 of this year, and free cash flow increased 47% on the same basis. On a year-over-year basis, operational cash flow increased more than ten times, leading to a huge increase in free cash flow. And non-GAAP gross margin, while not seeing an increase, saw fit to at least remain flat instead of decreasing. Not bad. Marvell's shares traded 8% higher in premarket action.

Here's the deal, though. I'm not sure I'd want to buy Marvell at this point in the dreadful economic cycle. Going back to the long-term price action, there's no escaping the significant decline in the stock price as a result of potential future weakness in its business. For example, recently, Melly Alazraki wrote about Apple's (NASDAQ: AAPL) iPhone and how sales of that device might be affected by the recession. Marvell is a supplier to the iPhone.

With the stock in single-digit territory, and with the global markets acting horribly, I just can't see buying Marvell. Indeed, I enjoyed the earnings report. But one must consider the company is unsure about demand for the stuff it sells going forward. Maybe Marvell might make a trade or something, but I'm not ready to go long-term on it just yet.

Disclosure: I don't own any company mentioned; positions can change at any time.

Marvell Technology Group Ltd. (NASDAQ: MRVL) shares are trading higher after tech bellwether Intel (NASDAQ: INTC) reported a first quarter profit of $1.44 billion, or 25 cents per share, in line with analysts' estimates. While many investors were expecting weak results, INTC noted in a press release that microprocessor sales were in line with seasonal trends, which could be a good sign for MRVL. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on MRVL.

After hitting a one-year high of $20.04 in July, the stock hit a one-year low of $9.77 in January. MRVL opened this morning at $10.76. So far today the stock has hit a low of $10.53 and a high of $10.95. As of 12:30, MRVL is trading at $10.91, up $0.41 (3.9%). The chart for MRVL looks bullish but deteriorating, 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 an August bull-put credit spread below the $7.50 range. A bull-put credit spread is an options position that combines the purchase and sale of put options to hedge risk in case the stock doesn't do what you think but still leverage nice returns. For this particular trade, we will make an 8.7% return in just four months as long as MRVL is above $7.50 at August expiration. Marvell would have to fall by more than 30% before we would start to lose money. Learn more about this type of trade here.

Broadcom Corp. (NASDAQ: BRCM) stock is falling after fellow chip manufacturer Marvell (NASDAQ: MRVL) indicated an outlook for the first quarter of this year that investors did not like the looks of. 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 BRCM.

After hitting a one-year high of $43.07 in October, the stock has hit a new one-year low today. This morning, BRCM opened at $17.75. So far today the stock has hit a low of $17.35 and a high of $18.73. As of 12:30, BRCM is trading at $17.66, down 93 cents (-5.0%). The chart for BRCM looks bearish and steady, while S&P gives the stock a positive 4 STARS (out of 5) buy rating.

For a bearish hedged play on this stock, I would consider a May bear-call credit spread above the $22.50 range. A bear-call credit spread is an options position that combines the purchase and sale of call options to hedge risk in case the stock doesn't do what you think but still leverage nice returns. For this particular trade, we will make an 8.7% return in two and a half months as long as BRCM is below $22.50 at May expiration. Broadcom would have to rise by more than 27% before we would start to lose money.

BRCM hasn't been above $22.50 since January and has shown resistance around $20 recently. This trade could be risky if the economic situation turns around, but even if that happens, this position could be protected by resistance BRCM might find at its 50 day moving average, which is currently around $23 and falling.

Marvell Technology Group Ltd. (NASDAQ: MRVL) stock is falling today after the company posted a third-quarter loss of $6.4 million after the close yesterday. While MRVL's revenue rose 46% to $758.2 million and EPS beat estimates, this revenue made its fourth-quarter guidance look weak. Wall Street was looking for 6% sequential growth rate in the current quarter; MRVL's forecast translated to 3% sequential growth. 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 MRVL.

After hitting a one-year high of $21.85 in December, the stock hit a one-year low of $14.50 today. This morning, MRVL opened at $15.59. So far today the stock has hit a low of $14.50 and a high of $15.59. As of 10:50, MRVL is trading at $15.02, down $1.63 (-9.8%).

Microsoft Corporation (NASDAQ: MSFT) might finally be on the verge of seeing the adoption of Vista, wrote Arnie Berman, chief technology strategist, at Cowen & Company late last week.

Berman surveyed 283 corporate IT buyers and found 47% of small- and medium-sized businesses will begin deploying Vista by December 31, this is up from 43% in a similar survey completed in February. 31% of larger enterprises plan to start rolling out Vista by December 31, up from 25% in the previous survey.

How to invest in the long-awaited Vista uptake? Play the Microsoft food chain stocks, particularly since most investors have given up on Vista's adoption, indicating this is where investors could get the most bang for the buck. Intel Corporation (NASDAQ: INTC), Nvidia Corporation (NASDAQ: NVDA) and Micron Technology Inc (NYSE: MU), Berman believes will be beneficiaries of Vista's adoption. Other investment plays include memory chip maker Qimonda AG (NYSE: QI), the drive makers Seagate Technology (NYSE: STX) and Western Digital Corporation (NYSE: WDC), and Marvell Technology Group Ltd (NASDAQ: MRVL), a supplier to the drive business.

In our past Intel blogs, the Fly has suggested Intel has capacity in place to start ramping 64 megabyte processors big time, on a scale Advanced Micro Devices Inc (NYSE: AMD) does not possess. Berman points out that Intel's enterprise value/sales ratio relative to AMD is close to an all-time low, meaning Intel is cheap relative to AMD despite AMD's recent poor stock performance.

Nvidia at 19x consensus calendar 2007 results has shown the ability to deliver favorable financial surprises and could provide the solution to the greatest potential bottleneck for Vista adoption, the graphic processors.

Micron is selling close to its $10.91 book value which historically has supported the stock and memory demand will increase with the new operating system.

Marvell Technology Group Ltd. (NASDAQ: MRVL) opened at $17.30. So far today the stock has hit a low of $16.61 and a high of $17.44. As of 1:15, MRVL is trading at $16.69, down $0.31 (-1.8%).

After hitting a one-year high of $28.27 in May 2006, the stock fell quickly and has been trading in the upper teens with strong resistance at 21 over the past ten months. Last night, Marvell reported that its Q1 revenue rose 22% to $635.1 million, but fell short of analyst expectations of $645.7 million, sending the stock slightly lower. Recent technical indicators for MRVL have been bearish but improving slightly, 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 an August bear-call credit spread above the $20 range. MRVL has not been above $20 for any significant amount of time since July and has shown resistance around $17.70. This trade could be risky if investors think the stock's slide is finished and start buying again, but even if this happens, the stock would have to rise by 18.8% before we would be in trouble.
