Advisors Opinion:

One under-$10 wireless services player that looks poised for a big spike higher is KongZhong (KONG), which is a provider of WVAS and mobile games to mobile phone users and a wireless media company providing news, content, community and mobile advertising services through its wireless Internet sites in the PRC. This stock is off to a hot start in 2013, with shares up sharply by 53%.

If you take a look at the chart for KongZhong, youll notice that this stock has been downtrending badly for the last two months, with shares plunging lower from its high of $14.92 to its recent low of $7.78 a share. During that downtrend, shares of KONG have been consistently making lower highs and lower lows, which is bearish technical price action. That move has now pushed shares of KONG into oversold territory, since its current relative strength index reading is 30.21. Shares of KONG are now starting to spike higher off its recent low of $7.78 a share and off its 200-day moving average of $7.95 a share. This spike could be signaling that the downside volatility for KONG is over in the short-term and the stock is ready to trend higher.

Traders should now look for long-biased trades in KONG if it manages to break out above some near-term overhead resistance at $8.50 a share with high volume. Look for a sustained move or close above that level with volume that hits near or above its three-month average action of 519,857 shares. If that breakout triggers soon, then KONG will set up to re-test or possibly take out its next major overhead resistance levels at $10 to its 50-day moving average at $11.33 a share.

Traders can look to buy KONG off any weakness to anticipate that breakout and simply use a stop that sits right below some key near-term support at $7.78 a share. One can also buy KONG off strength once it takes out $8.50 a share with volume and then simply use a stop that sits a comfortable percentage from your entry point.

Advisors Opinion:

Chipotle (NYSE: CMG ) has been talking about a potential price hike for a while, but it hasnt touched menu prices in over a year. Meanwhile, competitors like Panera Bread (NASDAQ: PNRA ) and McDonalds (NYSE: MCD ) have boosted prices, giving a lift to both sales and profits. In the video below, Fool contributor Demitrios Kalogeropoulos discusses whats kept Chipotle from doing the same, and what investors can expect from the company in the quarters ahead.

Last Friday, McDonalds (NYSE: MCD ) CEO Bob Thompson told CNBC that McDonalds may consider serving breakfast throughout the day. Starbucks (NASDAQ: SBUX ) and Panera (NASDAQ: PNRA ) have racked success with their breakfast offerings. Will McDonalds be able to take a bite out of the competition with all-day breakfast offerings? In this installment of MarketFoolery, our analysts talk about the business of breakfast.

This week, I want to highlight the co-CEOs of Panera Bread (NASDAQ: PNRA ). Ronald Shaich (a co-founder of Panera Bread) and Bill Moreton, and point out why theyve made such an incredible dynamic duo for shareholders, employees, and the community.

Another potential way that Chipotle could probably boost sales would be to raise its menu prices. Food costs have risen substantially, and McDonalds and Panera Bread (NASDAQ: PNRA ) have both successfully pushed price hikes through to customers. At the same time, though, Chipotle doesnt want to alienate customers at a time in which sales growth is already under pressure.

Advisors Opinion:

STMicroelectronics (NYSE: STM ) and OmniVision (NASDAQ: OVTI ) are the two camera suppliers, and HTC is reportedly no longer considered a tier one manufacturer so it doesnt get priority any more. That implies that one of these image sensor specialists was giving HTC the cold shoulder in favor of bigger names.
