Hewlett-Packard (HPQ -0.11%)faces the negative side of industrywide trends and is suffering big-time. Last quarter saw revenue fall by 5% and EBIT by 20%, and it had a $10 billion impairment. On top of that, its global market share declined by 2 percentage points, a substantial fall-off for such a large company.

While HP is still the world's largest PC maker, that gap is narrowing, with increased competition coming from Asia. However, the real problem is marketwide, affecting every player in the industry. It all comes down to the slowing demand for PCs, which flattened out in the second quarter of this year.

There were high hopes that Microsoft's (MSFT 1.65%)release of its Windows 8 operating system would drive upgrades and spur a turnaround, but that's looking less and less likely to be a growth catalyst of the magnitude needed.

Some investors may be intrigued by HP as a potential "value stock" right now, especially with dividends up above 3% and falling substantially over the course of the past year. However, Fool.com analyst Andrew Tonner classifies this as a textbook case of value stock versus value trap -- with HP landing squarely in the latter category. Shares may be empirically cheap, but they can (and probably will) continue to spiral downward.
