No. 7: Dell

Dell has been paddling furiously, but still lagging behind and losing business to Hewlett-Packard and Acer, among others.

The numbers. Dell told analysts last week that it would not build its turnaround on deep price cuts on PCs. But Dell didn't mention computer monitors. Black Friday will see another $100 price barrier shattered when Dell's S2009W 20-inch desktop monitor goes on sale for $99 at Best Buy. That price is 37% below the monitor's regular mark up of $159.

The stock. Dell shares are down 8% from Thursday levels when the company reported disappointing numbers, thinning margins and eroding market share. Dell's lousy performance came amid a surprisingly strong period of PC industry sales giving investors the sense that Dell may be missing out on a recovery.
