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.
