Cerner Corp. (NASDAQ: CERN) is a health care information technology provider, and that's a hot place to be right now.

The company reports on July 29, and earnings expectations are modest. In fact, only a third of covering analysts consider CERN a "buy," which leaves plenty of room for upgrades. The stock needs to break through potential resistance at $65, and earnings could give it that boost.

"The President made health care a centerpiece of his campaign, including investments in health care-related information technology (IT).

"Health care IT systems can save doctors' offices and hospitals significant administrative costs as well as prevent mistakes. In addition, some major health insurance firms are already putting heavy pressure on their physician networks to adopt these systems."

"Medical offices and hospitals are seeking to automate many functions, from storing patient records online to automatically submitting insurance claims for reimbursement.

"It's estimated that as much as 90% of health care records at smaller medical practices are still maintained in paper form, while even bigger hospitals keep close to half of their records manually.

"Quality Systems, a holding in our growth portfolio, is a leading provider of such systems. It sells software used to manage electronic patient records, billing, scheduling and other common administrative functions for medical and dental practices.

Way back in early March I highlighted 10 horrifically downtrending stocks and said not to even think about buying them until they broke their nasty trendlines to the upside.

Over the past few weeks, many have displayed solid sideways price action, but it wasn't until yesterday that the high volume breakouts occurred. I'm talking about those 50+ million shares traded, 10%+ price surges beautifully accomplished by such popular names like Sprint Nextel Corp (NYSE: S), Broadcom Corp (NASDAQ: BRCM) and Level 3 Communications Inc (NASDAQ: LVLT).

Unsurprisingly, several other stocks also showed similarly strong price action:

RF Microdevices Inc (NASDAQ: RFMD)
Anadigics Inc (NASDAQ: ANAD)
Skyworks Solutions Inc (NASDAQ: SWKS)
Triquint Semiconductor Inc (NASDAQ: TQNT)
China Life Insurance Co. Ltd (NYSE: LFC)
Raymond James Financial Inc (NYSE: RJF)
