The regular session's bearish movements bled into Thursday's after-hours session, and

Qualcomm

(QCOM) - Get Report

was leading the way with heavily traded losses.

The communication equipment maker's shares plunged after the company pegged fiscal 2008 income at a

subpar range of $2.03 to $2.09 a share, on a pro forma basis. Analysts polled by Thomson Financial are seeking $2.18 a share. The full-year revenue estimate leans to the lower end of consensus, as do top- and bottom-line estimates for the fiscal first quarter.

The San Diego-based company beat on both income and revenue for the fourth quarter, but shares were still sinking $3.06, or 7.7%, to $36.70.

Also heavily on the downside was

Allscripts Healthcare

(MDRX) - Get Report

. Shares were sliding 21.7% after third-quarter non-GAAP earnings totaled 11 cents a share vs. the Street's 15-cent forecast. The Chicago-based clinical-software developer also sees 2007 income of 48 cents to 49 cents a share on revenue of $286 million to $288 million. Both ranges would widely miss analyst calls. Shares were off $4.99 to $18.01.

Elsewhere, natural soda maker

Jones Soda

(JSDA)

swung to a third-quarter loss of 6 cents a share from last year's penny-a-share profit. Wall Street was looking for a profit of 2 cents a share, less extraordinary items. Shares of the Seattle-based company lost $1.09, or 12.3%, to $7.79.

On the other hand,

Priceline.com

(PCLN)

traded mostly in positive territory on far-better-than-expected pro forma earnings of $1.58 a share. Analysts were seeking just $1.28 a share. The discount travel Web site also raked in $416.9 million in revenue, which compares with the $387.5 million average estimate. Shares of the Norwalk, Conn., company were recently up 15.1% to $97.

Finally, California-based

Nvidia

(NVDA) - Get Report

more than doubled its third-quarter profit year over year to $235.7 million, or 38 cents a share. Excluding items, that comes to a better-than-expected 44 cents a share. The chipmaker's shares climbed 8.2% to $36.61 after briefly dipping into negative territory.
