What's better than momentum? Mo' momentum. Let's take a closer look at five of this past week's biggest scorchers.


Oct. 18

Weekly Gain







NQ Mobile (NYSE:NQ)



Chipotle Mexican Grill (NYSE:CMG)



Glu Mobile (NASDAQ:GLUU)

Let's start with Geron. The low-priced biotech soared after MLV & Co. initiated coverage with a bullish $6.50 price target. It's been a great run for Geron in recent weeks. The stock has nearly tripled since the beginning of September. Last week's analyst upgrade validates the gains.

SolarCity continued its massive run as the Elon Musk-backed installer of solar energy products succeeds in getting the market to buy into its model of installment payment-based installations that match the savings over traditional electric energy. SolarCity's rally continued despite the dilutive nature of a secondary stock and convertible debt offering.

NQ Mobile, a global provider of Internet services, moved higher after setting up a media event on Tuesday to introduce what it's calling "an exciting new product." The company will share the spotlight with Apple, which will be showing off its new iPads later in the day, but NQ Mobile is still turning heads by building up the hype.

Chipotle Mexican Grill once again proved why it's the class act of burrito rollers. The fast-casual poster child served up tasty quarterly results, fueled by a 6.2% spike in comps. Chipotle expects to open as many as 195 more locations next year. 

Finally, Glu Mobile moved higher after B. Riley upgraded shares of the mobile-app publisher. B. Riley pushed its price target from $2.75 to $3.75 in upgrading its outlook from "neutral" to "buy."

Glu Mobile and other casual-gaming specialists have been out of favor, but that's starting to change now that Candy Crush Saga creator King is generating buzz for its upcoming IPO.
