Michelle Obama has made healthy eating a priority in her role as first lady. Her emphasis on the earth-to-table approach to dining emphasizes local and organic ingredients -- and fits squarely with the mission of Whole Foods Market (NASDAQ: WFMI).

Obama's White House garden is great top-of-mind stuff and demonstrates the value of a healthy lifestyle. It may not be for everyone, but there will be enough followers that will think more and more about going organic.

We saw the first signs of the "Obama effect" with the hype of her inauguration gown. The designer of that stunning dress was Jason Wu.

I can imagine that many women looking to wear a stunning dress to their own special occasion might head to Nordstrom (NYSE: JWN) -- which carries Wu's collection.

In this recession, department stores need all the help they can get, and selling a hot designer is a great leg up on the competition.

Unlike Talbots, Chico's (NYSE: CHS) is already chic. This retail stock doesn't need a boost from Mrs. Obama, but an endorsement wouldn't hurt either.

Its White House/Black Market stores have seen explosive growth over the past decade and seem to have the type of products that would look good in the real White House.

In the immediate aftermath of the credit crisis, shares of CHS collapsed.

If ever a brand could use a boost it's Talbots (NYSE: TLB).

This week the company announced that profits plummeted 68% to $1.6 million in the quarter ended May 3.

This conservative women's clothing store has lacked the pizzazz to capture a larger market share. Michelle Obama wearing TLB injects some much needed life into the brand.

After the election, when it was known that Mrs. Obama wore Talbots, shares bounced significantly. Previously, the stock was threatening to broach the $1 mark. Today, you can buy shares for around $5.

We all know the impact that celebrities have on businesses. One of the most obvious instances of this phenomenon comes from the Oprah Winfrey Show. For example, when a title makes it into her book club, millions of loyal followers immediately take action, and sales follow.

These days, Michelle Obama is giving Oprah a run for her money. The First Lady is being closely watched by millions, and she too has a loyal following. She also appears to have a fashion sense that resonates with consumers around the globe. We all saw the number of stories and speculation about her gown during the inauguration.

With President Obama highlighting the national importance of cyber security, we turn to technology specialist Gregg Early to find the best investment ideas in the sector.

Noting that "cyber security is one of the biggest new sectors in the information technology industry," the editor of Personal Finance offers a trio of buys in the field -- McAfee (NYSE: MFE), Versar (AMEX: VSR), and Unisys (NYSE: UIS).

The advisor explains, "In exchange for an annual fee, McAfee allows users to download the basic security software and regular updates. These frequent updates are essential because virus and malware threats are constantly evolving.

"Over the past year, ITC Holdings (NYSE: ITC) has been focused on identifying ways to integrate wind and other renewable resources into the power grid," notes growth stock expert Alexander Green.

In The Oxford Club Communique, he explains, "This young company -- that despite being in the midst of the biggest economic slowdown in more than 70 years -- is taking in more than $600 million in annual revenue, enjoying 46% operating margins and experiencing 72% quarterly profit growth.

Brendan Coffey is a specialist on "green" investing; in his The Cabot Green Investor, he looks to alternative energy firm American Superconductor (NASDAQ: AMSC).

Here's his review of the company, which is a player both in wind power and energy efficient wiring that can play a role in improved power grid systems.

"Long an R&D company, focusing on highly conductive wiring, American Superconductor made a game-changing purchase of an Austrian wind company, Windtec, in early 2007.

"Zero greenhouse gas emissions, 90% average availability as a power source, minimal land requirements and competitive costs: those are just a few of the advantages of geothermal power," explains Roger Conrad.

In his leading-edge New World advisory, he looks at one favorite play on the sector: Ormat Technologies (NYSE: ORA), which operates a dozen geothermal plants worldwide.

"Geothermal's chief disadvantage is geographical limitations to large-scale applications. Geothermal plants are mainly economic in areas of subsurface or volcanic activity.

"A smart grid makes use of coded signals that travel along power lines, much like DSL broadband messages move through the phone telephone," explains growth stock expert Jim Powell.

In Global Changes & Opportunities Report, he looks at two favorite plays on the development of a smart grid: Esco Technologies (NYSE: ESE) and Quanta Services (NYSE: PWR).

"In a smart grid, the signals allow electric meters to report power consumption automatically to suppliers. At the same time, signals can be sent to customer's appliances such as freezers and refrigerators to prevent them from cycling on and off at the same time.

In February I interviewed Bill Gross back when the Dow traded at 7,182. Gross's message? Equities are dead. Or more specifically, in light of his expectation that there would be no economic growth for the foreseeable future, there was no point in risking an investment in common stock since it stands in line behind all sorts of debt for a piece of the cash flows of a company in the event of a bankruptcy.

Interestingly, President Obama spoke to reporters not long thereafter -- on March 3rd to be specific when the Dow was at 6,726 -- and during that talk, he mentioned that buying stocks might be a good deal. Since then, the Dow has risen 21.5% and since Gross recommended staying away from stocks, they've gained 13.8%. The Dow is at 8,175 as of this writing.

"Warren Buffett's Berkshire Hathaway revealed a new position in Nalco Holding (NYSE: NLC); it's my favorite pure play on water filtration," says Chris Mayer in Daily Wealth.

"With a $1.6 billion market cap, Nalco is a small-cap stock, but it's actually one of the world's largest water-treatment companies. Customers use Nalco's products and services to prevent corrosion, contamination, and the buildup of harmful deposits.

"Buffett picked up 8.7 million shares. That makes Berkshire the second-largest shareholder in the company, with a little more than 6% of the shares.It's easy to see what Buffett likes.

"The solar sector has been notably weak, including First Solar (NASDAQ: FSLR)," says Stephen Leeb. Despite the setback, the editor of The Complete Investor rates the stock a high risk buy.

"First Solar is one of the few whose earnings outperformed consensus estimates: its fourth-quarter results reported yesterday after the market's close were nearly 25% better than estimates.

"First Solar made $1.61 per share this past quarter; Wall Street was expecting $1.30 per share. Revenues were also ahead of estimates, although the company reduced 2009 revenue estimates by about 10%, citing short-term credit concerns for customers.

In his Validea newsletter, John Reese selects stocks using the investment strategies of the market's leading gurus, such as Benjamin Graham, John Neff, Warren Buffett, David Dreman, and Peter Lynch.

The advisor, and author of the just-published The Guru Investor, recently ran a screen based on the investment strategy of Kenneth Fisher to find his latest buy recommendation -- Kennametal (NYSE: KMT).

Reese explains, "For decades, the price-to-earnings ratio has been the most widely used valuation measure for stock investors, and a key tool in the arsenals of many of the gurus I follow. ut in 1984, Kenneth Fisher sent a shockwave through the P/E-conscious investment world.

"American Superconductor (NASDAQ: AMSC) should benefit from an update of the nation's power grid," says Jim Powell.

Here, the editor of Global Changes & Opportunities Report reviews this leading manufacturer of more efficient high temperature superconductor-based wires and cables.

"I've been writing about infrastructure stocks ever since it became apparent that big federal spending programs were on the way. I believe American Superconductor will perform very well. In fact, its price has already started to rise.

"American Superconductor is not yet profitable. However, the company is well past the development stage. AMSC makes high temperature superconductor (HTS) wires and cables that carry as much as 150 times the current as conventional products of the same weight and diameter.
