POPS (stocks that jumped higher)

Carnival Cruise (CCL) popped 3%. Investors hit the all-you-can eat buffet on the cruise line, after profits were up 12%. – Guy Adami doesn’t know what to say.

Motorola (MOT) popped 3%. Hello MOTO! Shares of the cellphone maker rang off the hook, after one analyst said that competitor Samsung's phones are so popular, that they'll be sold out for months, leaving Motorola to pick up the table scraps. – Jeff Macke says the stock is a sell.

Athenahealth (ATHN) popped 99%. Jonathan Bush, first cousin of George W, co-founded Athenahealth which offers internet-based billing solutions for doctor's offices. Shares were up a whopping 99% in its market debut. – Pete Najarian is impressed.

American Greetings (AM) popped 7%. The greeting card maker popped after posting a quarterly profit.

Monolithic Power Systems (MPWR) popped 15%. This maker of chips (for flat panel TVs and laptops) surged to an all-time high, after higher PC demand caused analysts to raise their price targets. – Pete Najarian calls it a big day for this stock.

Spin Rage. We're all guilty of having a little road rage when stuck in a traffic jam, but a Wall Street broker took the term to new heights while in a spin class at a New York City gym. A nearby spinner's "grunting" led the broker to pick up the grunter AND his stationary bike, and hurl them at wall. The victim, who happened to be a hedge fund manager, needed surgery to correct the spinal-cord contusion he sustained.

DROPS: (stocks that slid lower)

CKE Restaurants (CKR) dropped 6%. Investors got indigestion from the parent company of Hardee's and Carl's Jr., after the restaurant chain reported a 34% drop in profit. – Karen Finerman recommends YUM or MCD.

Pier One Imports (PIR) dropped 5%. Investors were "exporting" shares of Pier One Imports after the home furnishing retailer's losses exceeded analyst expectations. – Jeff Macke calls this company a strong contender for worst company in the world.

Lowe's (LOW) dropped 3%. The home improvement retailer found itself on shaky foundation, ahead of the company's analyst meeting on Monday. – Karen Finerman reminds the panel she’s long HD.

Infosys (INFY) dropped 5%. The India-based outsourcer fell after competitor ACI Worldwide cut its '07 guidance. – Guy Adami reminds the panel that the rupee is at 9-year high. Who needs to out-source when you can "in-source" he says.

Pacific Ethanol (PEIX) dropped 8%. $83 oil curiously didn’t help ethanol stocks. An analyst downgraded Pacific Ethanol and a host of other ethanol plays on declining prices. – Pete Najarian prefers solar.
