"Gilead Sciences (NASDAQ: GILD) develops treatments for life-threatening diseases and specializes in drugs for HIV, the virus that causes AIDS," notes Hannah Choe.

The contributing editor to Personal Finance explains, "Already the market leader in HIV antivirals, Gilead is in the beginning stages of developing Quad, the first-ever, four-in-one AIDS pill.

"The manufacture of HIV drugs, which accounts for more than three-quarters of revenue, is Gilead's highest-grossing business. This segment has held up through the recession; in the second quarter product sales for the antiviral franchise grew 26% from a year ago to $1.41 billion.

"Highly leveraged casinos were among the first to be locked out of credit markets last year," says Elliott Gue, noting that one company that suffered greatly from credit conditions was Las Vegas Sands (NYSE: LVS).

Now, however, he see "strong propsects" for a recovery in the casino operator's future; he is particularly optimistic on the firm's Asian projects. Here's his review from Personal Finance.

"The economic downturn meant consumers reined in spending on leisure travel and gambling. Meanwhile, declining real estate prices near Las Vegas hit the local economy hard. Gaming revenues declined, and occupancy at Sin City's massive hotels plummeted.

"The term cloud computing is nothing particularly new or complicated; it simply means that instead of having software on your home, office or notebook computer, you run applications over the Internet," explains Gregg Early.

In Personal Finance says, "It's the way of the future as computing becomes increasingly mobile." Here, he looks at a trio of plays on this trend: Amazon.com (NASDAQ: AMZN), Salesforce.com (NYSE: CRM), and Rackspace Hosting (NYSE: RAX).

One of the most valuable commodities in the world is water -- without it, mankind can't survive. While more than 70% of the Earth's surface is covered by water, but 97% of it is saltwater and only 1% of the remaining 3% is readily available for consumption. Water is becoming scarce, and upcoming water shortages are emerging as the population of the world increases, particularly in emerging markets like China, India, and Mexico.

A great way to include water as part of your portfolio's commodity allocation is by buying an exchange-traded fund (ETF). An ETF is a basket of stocks that allow you to invest in a single asset class, sector, country, or theme with one stock. In one ETF, you'll own not only water utility companies but also related businesses, like those that help build the infrastructure for making water suitable for drinking. You won't have to pick a single stock, rather you can own the most important stocks in the water industry -- worldwide. ETFs are perfect building blocks for building a diversified portfolio using an asset allocation strategy.

"By 2017, wireless service providers could generate more than $100 billion from services such as text messaging, GPS and movie, and music downloads " says Roger Conrad.

In Personal Finance, he adds, "Even this forecast could prove extremely conservative thanks to an explosion in sales of smartphones." How to play this trend? Here, he looks at Research in Motion (NASDAQ: RIMM).

"Smartphones account for only 11% of the world's mobile handsets; penetration remains under 20% in the U.S. This leaves plenty of room for further growth.

"Investors have given up on the water industry -- the sector has fallen 60% -- but the best firms have hardly missed a beat," says utility sector specialist Roger Conrad.

In Personal Finance, the advisor reviews the outlook for the sector and two of his favorite stocks -- American Water Works (NYSE: AWK) and Aqua America (NYSE: WTR).

"The EPA stimates the US will have to spend $335 billion over the next decade to keep the taps turned on, given aging infrastructure and supply degradation.

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.

With President Obama at the helm it seems as though the light might be shining on the economic horizon. If you're of this opinion then now might be a good time to invest some of your hard earned savings in the banking industry.

But what banking firm do you decide to go with? Rather than selecting just one bank, how about hedging your bets by investing in many diverse banks from all over the country? An exchange traded fund (ETF) is a great way to do just that. By investing in the ETF PowerShares Dynamic Banking (PJB) you get shares of several different banks. PJB seeks to replicate the Dynamic Banking Intellidex index and invests at least 90% of assets in common stocks that comprise that index. Among their holdings in the PJB ETF are BancFirst Corporation(NASDAQ GS: BANF) BancFirst's holding company, Capital Federal Financial(NASDAQ GS: CFFN) the holding company for Capitol Federal Savings Bank, and Northern Trust Corporation(NASDAQ GS: NTRS) Northern Trust Company's holding company.

"Earnings prospects for companies in the information technology (IT) sector are surprisingly resilient, and one of the best-placed and most recession-resistant IT stocks is IBM (NYSE: IBM)," notes Elliott Gue.

In Personal Finance, he adds, "In the recession of 2001, tech stocks were among the hardest hit groups in the S&P 500, but that was mainly a hangover from the technology bubble of the late 1990s that saw many big-cap tech firms soar to unprecedented valuation levels.

"The tech sector today bears no resemblance to what it was in the early part of this decade. The S&P 500 IT sector now trades at a slight valuation premium to the S&P 500 as a whole, and many of the largest names have impressive, cash-heavy balance sheets.

"Master limited partnerships have been among the market's most stable and reliable groups; but 2008 was a painful exception, with the benchmark index down nearly 37%, the worst performance in its 13-year history," says Elliott Gue.

In Personal Finance he now sees a "great opportunity" for investors to takes positions in this high-yielding sector. Here's a trio of favorite investment plays in the MLP arena.

A long-term developing trend in Asia, according to international investing expert Yiannis Mostrous, is a rise in domestic demand within their own economies.

In Personal Finance, he looks at one favorite sector that will benefit -- wireless phone services -- and highlights two of his top choices, Chunghwa Telecom (NYSE: CHT) and China Mobile (NYSE: CHL).

"The current crisis will lead to profound changes in the global financial system. Societies in developed economies will begin to save more, while people in developing nations will begin to spend, nurturing domestic demand economies.

"The Asian economies should be able to move even closer to their ultimate economic goal: domestic demand-led economies.

"These countries have realized that factory building and manufacturing to satisfy consumer needs in the developed world can't remain their primary growtth engine.

"Investing in food is a simple story: expanding supply and demand fueled by rising global urbanization," says Yiannis Mostrous. In Personal Finance newsletter the global advisor looks at Monsanto (NYSE: MON).

"The global population is expected to surpass 9 billion by 2050. Wages are rising in emerging economies--led by India and China--and more people are moving into cities where the consistent and better paying jobs are.

"That means greater demand for protein-rich foods, especially meat and dairy consumption. The consumption of both has a strong correlation to urbanization. The result will be a permanent increase in demand for crop grains for feeding.

"One of my favor defensive sectors is healthcare," says Elliott Gue; the contributing editor to Personal Finance looks to Quality Systems (NSDQ: QSII), a company that helps automate medical records.

Quantitative analyst Richard Moroney also sees opportunity in the same niche sector. In his Upside newsletter, he looks to a competing play, Cerner (NASDAQ: CERN). Here are their reviews.

"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.

Last year global stock markets lost $29 trillion in value -- falling 42%. And although it does not get much media attention, there is something that investors can do when the stock market moves against them. They can set stop losses on their stocks which limit how much money they can lose. Specifically, if an investor buys a stock at, say, $20 a share, he or she can issue a limit order which requires the broker to sell the stock when it declines to a lower price, say, $18. Such a limit order would limit the investor's loss to 10%.

This comes to mind in considering why the average stock in my investment newsletter gained 15% in 2008 when the S&P 500 fell 38.5%. My monthly newsletter analyzes broad economic trends and bores into specific industries. It also picks three stocks each month for subscribers to consider. During the first half of 2008, the energy and commodities stocks mentioned boosted its performance to +29% through the end of June. Then the bottom began to fall out as commodity prices tumbled and the financial services industry collapsed.

Thanks to the 2% stop loss rule -- which automatically sells any stock that falls 2% below the price at which it was mentioned in the newsletter -- the low point for the year was -1% at the end of October. By the end of 2008, only four of the 36 stocks mentioned remained in the portfolio. However, thanks to a surprising boost in one stock mentioned at the end of October and the three stocks picked at the end of November, the average stock was up 15% by the end of 2008. What were the three best performers?

This is the time when investors sell their losers, take their losses, and use them to reduce their taxes. The sharp drop in the stock market could cause one of the biggest waves of tax-loss selling in several years.

Investors can carry forward tax losses indefinitely and use them to offset future gains. Let's take a specific example and assume that you have short-term loss of $8,000 and a long-term gain of $3,000. You would have a remaining loss of $5,000. This loss can be carried forward indefinitely. However, you can deduct only $3,000 a year against ordinary income. You must designate your loss as either short or long term.There is another rule which says that you can buy stocks to replace the ones you've sold, but you cannot buy back the same stock.

This year, for some people, the losses are so large that it will take them the rest of their lives to use them up. Many investors wait until the last two or three days because they have an aversion to "biting the bullet," so to speak. There is a different psychology in selling, especially selling at a loss. Often your emotions and your ego come into play; I know some people who understand the tax laws and still refuse to take advantage of them. I often hear them say: "I'm going to keep this stock because I know it will come back next year." Others agonize and torture themselves, going back and forth weighing the advantages of selling against their refusal to admit to mistakes. Still others rely on their brokers or financial advisors and blame them for their losses.
