There's never a shortage of losers in the stock market.

Let's take a closer look at five of this past week's biggest sinkers.


Feb. 24 Weekly Loss My Watchlist
Vocus (Nasdaq: VOCS) $13.52 (40%) Add
Career Education (Nasdaq: CECO) $8.20 (31%) Add
YRC Worldwide (Nasdaq: YRCW) $8.64 (28%) Add
Dendreon (Nasdaq: DNDN) $11.14 (25%) Add
First Solar (Nasdaq: FSLR) $30.02 (16%) Add

A couple of analysts downgraded Vocus after the marketing software company bought email marketer iContact in a $179 million deal.

Career Education didn't land a passing grade with investors after posting its latest financials. Revenue slipped 17% to $440 million, and an operating profit a year earlier was transformed into a chunky operating loss this time around.

Credit Suisse downgraded its price on YRC Worldwide -- from $15 to $6 -- after the recently restructured trucking company warned that it may need to request some more leniency out of its creditors.

Dendreon tumbled after uninspiring quarterly results coupled with soft guidance for the current quarter. Dendreon's prostate cancer treatment Provenge is a blockbuster, but apparently a slow-moving one.

First Solar set on investors after posting a weak quarter. The solar energy miss even hosed down forecasts as competition in First Solar's niche is intensifying.
