At the midpoint of 2005 and just ahead of another earnings season, it's time to examine where investors can find the most potential for returns in the second half of the year.

My screening models indicate that the technology sector holds the most promise. I believe that the macroeconomic backdrop, business trends and acquisition action favor tech's chances as well.

Very Undervalued

Gains seen in the

Nasdaq

and SOX since the April lows point to a rotation into technology, which my models show as the cheapest sector, at 20.9% undervalued. The Nasdaq declined 5.4% in the first half of 2005, but since the April low of 1890, it's up 7.0%.

I have been tracking the Philadelphia semiconductor index for a major, chart-related moving-average crossover, with the SOX off 3.3% in the first half -- but up 11.3% since its April low of 376.64.

According to my models, as the second half of 2005 begins, all sectors are fundamentally cheaper than they were at the end of 2004. As the table below shows, basic industries, energy and transportation ended 2004 more than 20% overvalued. Of these, only energy remains overvalued, but only by 6.3%. The largest swing was in transports, which went from 28.4% overvalued to 5.1% undervalued.

My model shows that technology continues to be where the value has been and should be for 2005. Technology begins the second half of 2005 at 20.9% undervalued, vs. 11.7% undervalued at the end of 2005.

Among my technology indices of focus, computer manufacturers are 31.8% undervalued, semiconductors are 28.0% undervalued, and software is 22.5% undervalued.

In sum, away from technology, most sectors are within 5% of their fair value, with health care 9.3% undervalued and energy 6.3% overvalued. This is a compelling case for focusing on technology in the second half of 2005.

Economy on Solid Ground

Last week's better-than-expected readings for consumer sentiment and a higher-than-expected reading for ISM tell me that the economy should maintain a GDP growth rate of roughly 3.5% for the foreseeable future. The economy should not be hurt by a 4.25% neutral funds rate, which I predict will be declared by the end of the year, just in time for

Fed

Chairman Alan Greenspan to be congratulated at his retirement.

Commodities prices appeared stalled last week, but crude oil remains a wild card. With a strong dollar and higher Treasury yields, there could be a rotation into the U.S. equity markets, with technology being the sector of choice.

Tech's Compelling Growth

In tracking technology leadership, my first focus was the chipmakers, but now a major upgrade cycle is needed in the Internet protocol segment. This industry is estimated to have grown by 50% year over year. Retooling the Internet with an expansion of the use of broadband will drive IT spending in the second half of 2005.

In June, the Semiconductor Industry Association reported that chipmakers were quickly working off excess inventory. The trade group predicts sales growth of 6% this year. Both

and

Texas Instruments

(TXN) - Get Report

were among the semiconductor giants offering positive guidance for the second half of 2005; this backs up the SIA's prediction.

Other growth segments include:

  • WiMax, a version of WiFi, but with an expanded range of some 10 miles.
  • Voice over Internet protocol (VoIP), which gives high-speed Internet providers a triple threat with television service, phone and broadband Internet access bundled into one package.
  • Growth in the use of cell phones, with Nokia (NOK) - Get Report, the industry leader in handsets, predicting a 15% growth rate for 2005 over 2004.
  • A PC upgrade cycle, which will be driven by dual-processor components, which are necessary to handle the multitasking that the new Internet will provide.

Growth Through Acquisition

The acquisition game should continue in the second half of 2005.

Oracle

(ORCL) - Get Report

is successfully integrating PeopleSoft into its stable of enterprise software applications, and it has more money to spend.

Symantec

(SYMC) - Get Report

just completed the purchase of

Veritas

(VRTS) - Get Report

, combining security software and enterprise applications.

Cisco Systems

(CSCO) - Get Report

has continued acquiring smaller companies, but a rumor surfaced last week that its next deal could be a blockbuster: the purchase of storage giant

EMC

(EMC)

.

Sun Microsystems

(SUNW) - Get Report

is in the process of purchasing

StorageTek

(STK) - Get Report

with the strategy of becoming an IT consolidator and targeting the major data centers around the world. Finally, there's

Time Warner

(TWX)

and the question of what to do with its America Online unit.
