"Our top pick for 2010 is engineering and construction (E&C) firm AECOM Technology (ACM)," says Geoffrey Seiler.

In his BullMarket.com the advisor explains, "AECOM, unlike some better-known E&C names, offers a relatively low-risk business model. It performs no construction work at all and thus has none of the lump-sum, fixed-rate contracts that other companies might sign."

Technology expert Gregg Early looks to AeroVironment (AVAV) as his top pick for the coming year.

The editor of The New Tech Investor -- and the soon-to-be-launched Portfolio 2020 -- he explains, "Although the firm's military aerospace business should be strong, it is the firm's new 'clean technology' and energy efficiency projects that should be the real growth kicker."

"The Energy Security Act of 2007 has received little investor attention; however, it contains provisions that are likely to lead to significant returns for investors," suggests Andy Obermueller.

In his Government-Driven Investing, he notes, "The law codifies the federal production targets for biofuel, which we believe presents a real opportunity for Vernenium (VRNM)."

Two growth stock specialists have turned bullish on the prospects for medical equipment maker Varian Medical Systems (VAR), despite uncertainty surrounding health care legislation.

Here's a look at the company from Louis Basenese, senior analyst with The Oxford Club, along with commentary from Mark Skousen, from his specialty service, The Turnaround Alert.

Mark Skousen suggests, "One stock that should benefit from 'ObamaCare' is Varian Medical Systems, the world's leader in radiation technology and X-ray imaging.

In his The Long and Short Stock Advisor, growth stock specialist Sy Harding looks to Kaydon (NYSE: KDN), a maker of custom-engineered aerospace, defense, medical and wind-energy products.

He explains, "Kaydon's revenues (and stock price) held up well through most of last year before succumbing to the plunging economy.

"As with most companies tied to the economy, Kaydon's earnings declined in 2008 and so far in 2009, resulting in a decline in the stock price. However, the company is seeing improvement so far in the second half of the year.

"The uncertain market has changed our risk appetite and shifted our focus to stocks deemed safe enough for even the most conservative investors," says Jonas Elmerraji.

The editor of The Rhino Stock Report suggests, "Among them are regulated utilities, including our latest recommendation -- NRG Energy (NRG), which is involved in wholesale power generation.

"Investors have long favored utilities for a few very good reasons: predictable, recession-resistant revenues; steady streams of dividends; and government-sanctioned monopolies. They're a safe haven for stressed investors in the midst of a recession.

"Being socially responsible means different things to different people; however, in the mutual-fund world, it refers to funds that combine progressive 'social' mandates with investment criteria," explains fund expert Mark Salzinger.

In The No-Load Fund Investor, he suggests, "We have no problem with the concept of socially responsible funds for an investor who wants his investments to reflect his values, provided that the funds have also provided good risk-adjusted returns." Here, he looks at two favorites.

"Funds that call themselves socially responsible usually avoid stocks that don't meet progressive, or politically liberal, standards of environment impact, workplace environment, and diversity/tolerance and community involvement.

In his Ticker Tape Digest, technician Leo Fasciocco looks for "breakout" stocks; his latest feature is HMS Holdings (HMSY), which coordinates benefits for government healthcare programs.

"With annual revenues of $185 million, HMSY helps ensure that healthcare claims are paid correctly and by the responsible party.

"As a result of the company's services, government healthcare programs recover over $1 billion annually and avoid billions of dollars more in erroneous payments.

"I'm excited about Quanta Services (PWR), a contracting company that specializes in building utility transmission and distribution infrastructure," says Ian Wyatt.

In his Top Stock Insights, he explains, "The current focus in the U.S. of projects that improve energy conservation, utilize renewable resources, and improve air quality make Quanta an excellent long-term growth opportunity.

"Its customers are in the electric power, gas, telecommunications, and cable television industries. These are stimulus spending customers; i.e., big government organizations and utilities companies.

"The U.S. Energy Department is sponsoring a race to develop an obscure industrial process -- carbon capture and sequestration (CCS) -- and the winners of the race will receive $1.4 billion -- yes, billion, with a B," says Andy Obermueller.

In Government-Driven Investing, he says, "My pick to profit from among the 12 companies selected to compete in this scientific 'Olympiad' is Praxair (NYSE: PX)."

"This industrial-gas company owns hundreds of CCS patents, technology that could turn a coal-fired power plant -- about the dirtiest thing in the world, emissions-wise -- into one of the cleanest.

"Water, one of the most precious of resources, continues to be the most mispriced," says Neil George.

In his Profits Hidden in the News advisory, he explains, "Millions of Americans are drinking dangerous water from the tap." Here, he looks at two ways to profit as this situation gains attention.

"The US Environmental Protection Agency has recently updated its data on US municipal water and, as with previous surveys and reports - the news is not good. In fact, for wide swaths of the US population - including those in the nation's capital - its flat out scary.

"The health care picks in our growth portfolio should prosper whatever the outcome of the raging health care debate," suggests growth stock specialist Stephen Leeb.

In The Complete Investor, he explains, "That's because they're leveraged to demographic realities, and in particular to the tide of aging baby boomers," Here, he reviews on portfolio holding -- Teva Pharmaceuticals (NASDAQ: TEVA).

Leeb says, "Israel-based Teva Pharmaceutical is the world's largest manufacturer of generic drugs. Capitalized at $49 billion, Teva pulled in some $11 billion in revenues in 2008, with generic drugs contributing more than two-thirds of those sales.

"A smart grid is one of the holy grails of 'green' technology, enabling utilities to deliver resources when and where they're needed and reduce resources when they're not," says Brendan Coffey.

In The Cabot Green Investor, he explains, "There are larger companies in the smart metering arena, but Echelon (NASDAQ: ELON) has posted some significant wins in the marketplace recently and appears primed to generate more."

"Right now, grids are set up to provide as much power as needed at peak times, all the time. Studies show that when customers are part of a smart grid, and have more information to reduce energy usage, demand is slashed by up to 50%, particularly in areas where rates are discounted depending on the time of day.

"Coal accounts for more than 70% of China's electricity," says Tony Sagami. In Uncommon Wisdom, he looks to an ETF poised to benefit from long-term rising coal demand.

The advisor explains, "China's coal consumption is growing, and it is building coal-powered power plants at a breakneck pace.

"Why? Because they are much cheaper to build and operate than any other power-producing option. China is power starved, and coal is the main resource used for generating electricity in the country.
