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)
Cerner Corp (NASDAQ: CERN)

As its name would imply, TriQuint Semiconductor (NASDAQ: TQNT) is in the chips business. The company maintains a niche in the competitive field by using materials other than silicon to manufacture circuits for use in cell phones, fiber-optic equipment, and other technology. Specifically, TQNT manufacturers its devices with gallium arsenide (GaAs), which can operate faster and more efficiently than its silicon rivals.

After a rough fall from the top along with the rest of the technology sector during the early part of the decade, TQNT has started to show some renewed strength. The equity's relative strength compared to the S&P 500 Index has been impressive of late, with the shares outperforming the broader market since early April.

My recent Investing in Oregon post took a look at some companies that the Motley Fool had featured in its investigation of investment opportunities in the Beaver State, including Precision Castparts Corp. (NYSE: PCP), StanCorp Financial Group Inc. (NYSE: SFG), FLIR Systems Inc. (NASDAQ: FLIR), and Columbia Sportswear Co. (NASDAQ: COLM).

But the Motley Fool article also mentioned that one of the most prominent business influences in Oregon wasn't even headquartered in the state: semiconductor giant Intel Corp. (NASDAQ: INTC) from Santa Clara, California. It also included mention of four Oregon-based businesses that provided support for Intel: Tektronix Inc. (NYSE: TEK), Mentor Graphics Corp. (NASDAQ: MENT), Triquint Semiconductor Inc. (NASDAQ: TQNT), and Electro Scientific Industries Inc. (NASDAQ: ESIO). One could imagine that Intel's impressive earnings report this week should have been good news for these supporting companies.

Beaverton-based Tektronix, widely known as Tek, is one of the leading makers of test and measurement equipment, such as digital multimeters, logic analyzers, and curve tracers, and oscilloscopes. Tek will win its seventh technical Emmy this year. Tek beat Wall Street expectations in its previous three quarters, reporting earnings per share of 40 cents for its first quarter FY2008. But the consensus of analysts surveyed by Thomson Financial was to hold shares of Tek. The share price reached a 52-week high of $37.95 on Monday when it was announced that Danaher Corp. (NYSE: DHR) will acquire Tek. Tool and equipment maker Danaher just announced record third quarter results.
