If there was any doubt whether the rally at the end of 2008 and the beginning of 2009 was anything but a bear market rally, this week put these doubts to rest. The Dow Jones Industrial Average is already down 8.3% year-to-date; it sank 6.2% this week alone (notwithstanding Friday).

This week the financial crisis once again took center stage as Bank of America (NYSE: BAC) and Citigroup (NYSE: C) received a second round of bailout money and more guarantees. BAC is finding hard to digest its two acquisitions, while Citi is splitting itself and is no longer a financial supermarket.

But this wasn't all that happened this week. The fourth-quarter earnings season kicked off Monday; Alcoa (NYSE: AA) reported dismal numbers, all the rest followed suit. Even if there were a few surprises to the upside that exceeded expectations, the expectations themselves were already quite low.

For 26 years, at the start of each year, I've conducted an annual survey of newsletter advisors, asking for their favorite investment for the coming year. Until 2 or 3 years ago, their responses were almost always individual stocks and an occasional mutual fund.

Increasingly in recent years, many advisors have found their favorite positions to be exchange traded funds, whereby they can invest in a sector, region, or strategy without the inherent risk of an individual company. Indeed, in this year survey of 75 advisors, fully 1 out of 5 advisors chose ETFs.

ETFs were a popular choice for those seeking global exposure. Mark Salzinger, editor of The Investor's ETF Report, selects the S&P China SPDR (NYSE: GXC) as his favored play. (Read the full article here.)

Nick Vardy sees opportunity in China, but also sees potential in a broader range of emerging global markets. The editor of Global Stock Investor looks to the iShares MSCI Emerging Markets (ASE: EEM) as his top idea for 2009. (Read the full article here.)

Carl Delfeld of Chartwell Advisors also wants to own a basket of emerging markets stocks, but only small caps. His pick is the WisdomTree Emerging Market Small Cap (NYSE: DGS). (Read the full article here.)

Jim Lowell takes a similar view -- chosing global small caps -- but adds a further restriction. His recommended ETF limits its holdings to dividend paying stocks. Hence, the top pick in his Marketwatch ETF Trader is the WisdomTree International Small Cap Dividend (NYSE: DLS). (Read the full article here.)

ETFs an also be used to play a specific sector, such as consumer stocks. Leonard Goodall sees upside in companies making the "basics" such as soda, toothpaste and soap. In his No-Load Fund Investor, his top way to play this trend is the Consumer Staples ETF (NYSE: XLP). (Read the full article here.)

In addition to using ETFs to invest in a region, country or sector, these vehicles can also be used to invest in a certain strategy. For example, Tom Bishop, editor of BI Research, chooses the PowerShares Value Line Industry Rotation ETF (NYSE: PYH), which rotates its holdings to only include stocks that earn Value Line's top investment rating. (Read the full article here.)

Doug Fabian, editor of Successful Investing, looks to PowerShares DB Crude (NYSE: DXO), an exchange-traded note. While this leveraged position goes up twice as much as the underlying index when it rises, it also goes down twice as much when the index declines. (Read the full article here.)

Paul Tracy, editor of StreetAuthority Market Advisor takes a similar approach, but rather than speculate on the price of oil and gas, he looks to ProShares Ultra Oil & Gas (NYSE: DIG), which invests in a basket of stocks operating within these sectors. (Read the full article here.)

The most popular choice in this year's survey was ETFs investing in gold. Both Vivian Lewis, editor of Global Investing, recommends the SPDR Gold Trust (NYSE: GLD); it's price reflects 1/10th of an ounce of gold. (Read the full article here.)

Mary Anne Aden, editor of The Aden Forecast, also selects the SPDR Gold Trust (NYSE: GLD) as her top investment ideas for the coming year. (Read the full article here.)

Mark Leibovit, market timer and editor of VRTrader, holds a long-term bullish view on gold and opts for upside leverage. His top pick is the PowerShares DB Gold Double Long (NYSE: DGP). (Read the full article here.)

Pamela Aden, co-editor for The Aden Forecast, also sees upside potential in gold but prefers to invest in the companies that mine for the precious metal. Her top pick is the Market Vectors Gold Miners (NYSE: GDX). (Read the full article here.)

For greater leverage (and higher risk), Steve Rawls, editor of Tipping Point Stocks, suggests the ProShares Ultra Gold (NYSE: UGL), which moves twice the rate of the underlying London gold price. (Read the full article here.)

Mike Larson, editor of Money & Markets, sees downside risk in financial stocks. But rather than try and select which stock might fall, he opts for a basket of financial players with the ProShares Trust Short Financials (NYSE: SEF). As an "inverse" fund, this moves in the opposite direction of the underlying index. (Read the full article here.)

And for even higher risk and volatility, Michael Shulman, editor of ChangeWave Shorts, looks to the ProShares UltraShort Financials (NYSE: SKF), an inverse double fund. Not only does it move in the opposite direction of financial stocks, but it moves twice as much. (Read the full article here.)

Steven Halpern's TheStockAdvisors.com offers a daily look at the latest market commentary and favorite stock picks and investment ideas from the nation's leading financial newsletter advisors.

This post is part of a special annual report -- Top Stock Picks '09 -- in which TheStockAdvisors.com asked 75 leading newsletter advisors to select their favorite investment for the new year.

"My favorite idea for 2009 is a defensive play -- the Consumer Staples SPDR (NYSE: XLP)," says Leonard E. Goodall in his No-Load Portfolios. Here's his review of the exchange-traded fund.

"My recommendation of Consumer Staples SPDR is based on my assumption that the U.S. and world economies will continue to decline through most of 2009, hitting a bottom in the fourth quarter of 2009 or the first quarter of 2010.

"If I thought the economy would recover sooner, I would prefer stocks and funds that are more aggressive in investment strategy.

"XLP provides good investor protection in an uncertain economy. Its major holdings include Colgate, Coca-Cola, PepsiCo, CVS, Walmart, and Procter & Gamble.

"In tough times people will continue to buy toothpaste, medicines, soap, and other necessities. Of course, two of its other large holdings, Altria and Anheuser Busch, recognize they will also continue to drink and smoke!

"If you're going to stay invested, you should look to defensive sectors," explain Ron Rowland and Brandon Clay, who point to consumer staples as a top pick for the current market environment.

In their Invest with an Edge, the advisors explain, "Perhaps the best way to stay defensive is with the Consumer Staples Select Sector SPDR (NYSE: XLP), an exchange traded fund.

"In a bear market, opportunities are usually limited to certain sectors. Surveying the investment horizon, we think the consumer staples sector has the best opportunity for growth in this economy.

"Regardless how the economy acts, people still eat. Consumers may not shop at Whole Foods, but they'll still buy groceries. Companies like Wal-Mart (NYSE: WMT) and Safeway (NYSE: SWY) will continue to rake in revenues from hungry customers.

"In addition, these companies should continue to receive additional revenue from consumers who normally shop at specialty stores, but can no longer afford to.

"Consumers may not be shopping at Sharper Image any more, but there are other creature comforts that will be difficult for Americans to abandon.

"Coca-Cola (NYSE: KO) and PepsiCo (NYSE: PEP) will still sell products during a prolonged downturn. In addition, companies providing toiletries and convenience like Procter and Gamble and CVS Pharmacy stand to do well during a shifty economy.

Although the S&P 500 index is up 7.04% for the year (through yesterday's close), consumer-related shares have not kept pace.

For instance, the consumer discretionary sector (which has an equivalent exchange-traded fund, or ETF (AMEX: XLP)), has gained just 1.07% since the end of December, a difference of more than six percentage points. Given the meltdowns in the housing market and the subprime finance sector, the disparity is not all that surprising.

However, the consumer staples sector (which has an equivalent exchange-traded fund, or ETF (AMEX: XLY)), has also lagged the broad market. It is up 4.55% year-to-date, a performance gap of more than one-and-a-half percentage points.

Despite reassurances to the contrary from economists, pundits, and policymakers, it would seem that investors are anticipating an across-the-board slowdown in consumer spending.

In "GDP data adds to negative outlook for stocks," I noted that various measures are signaling that a recession is imminent and that it would be bad for stocks, at least in the short run.

Under the circumstances, one course of action is to eliminate or reduce exposure to equities to minimize the risk of loss. For investors who must or prefer to remain invested, the best strategy is to avoid vulnerable sectors and favor those characterized as "defensive."

Based on what happened during the last two recessions, in 1990 and 2001, the two sectors that would best serve as safe havens during an economic storm are Consumer Staples (which has an equivalent exchange-traded fund, or ETF (AMEX: XLP) and Health Care (AMEX: XLV) . Both ended up in the black six months after those downturns began, in contrast to the overall market.
