These exchange-traded funds promise to do as well as their mutual-fund counterparts at a fraction of the cost Thinkstock By Steven Goldberg, Contributing Columnist December 23, 2014 Exchange-traded funds continue to proliferate like kudzu. Many of them invest in overly narrow market niches or charge excessive fees. But if you look carefully, you can find dirt-cheap ETFs that will do at least as well as traditional mutual funds that often charge more. With ETFs, you get to pocket the cost savings in the form of higher returns.See Also: Our Favorite No-Load Mutual Funds I don't consider the picks described in this article to be buy-and-hold investments. I think U.S. and foreign stocks will earn you money in 2015, but plainly U.S. stocks are no longer cheap, and foreign economies—both developed and emerging—face strong headwinds. Meanwhile, bonds look wildly overpriced to me (see 5 Great Bond Funds for 2015). The bottom line: Beating the market isn't nearly as important as not getting creamed. That means sticking mainly to blue chips both here and abroad, taking special care in emerging markets and limiting interest-rate sensitivity in bonds. With that in mind, below are my five favorite ETFs—in no particular order. Advertisement Compared with Morningstar's widely known and admired fund research, the firm's stock research gets short shrift. But Morningstar's stock research is equally as good. Market Vectors Morningstar Wide Moat ETF (symbol MOAT) draws on the work of the firm's 100-plus stock analysts. Each quarter they collectively pick for this ETF the 20 companies with large and sustainable competitive advantages that are trading at the widest discounts to their estimates of fair value. The ETF launched in 2012, but an exchange-traded note that is based on the same methodology has been around since 2007. Largely because it holds so few stocks and can heavily overweight sectors, the ETN has been about 20% more volatile than Standard & Poor's 500-stock index. But because the stocks are of such high quality, the ETN has held up reasonably well in lousy markets, such as the 2007-09 bear market and the 2011 correction. Since its inception in 2007, the ETN returned an annualized 11.1%—an average of 4.6 percentage points better than Standard & Poor's 500-stock index. The ETF charges annual expenses of 0.49%. (All returns in this article are through December 18, unless otherwise noted.) Keeping things simple and sticking to a strict discipline is a recipe for successful investing. Consider Vanguard Dividend Appreciation (VIG). It tracks the Nasdaq U.S. Dividend Achievers Select index, which includes only companies that have hiked their dividends for at least 10 straight years. The index also excludes companies with weak balance sheets or unsustainable dividend policies. The stocks are weighted by market value (share price times number of shares outstanding). The high-quality portfolio that results tends to overweight consumer and health care stocks. The ETF yields just 2.0% but returned an annualized 8.0% since its inception in 2006—an average of 0.3-percentage point per year more than the S&P 500. Like Morningstar's ETF, the fund held up better than most in the 2007-09 and 2011 downturns. Expenses are a mere 0.10% annually. Since 2011, emerging markets have been terrific places to lose money. Over the past four years, the MSCI Emerging Markets index has returned an annualized –1.6%. I still buy the long-term emerging-markets growth story, but I'm pulling in my horns. Rather than investing in an ETF that tracks the MSCI Emerging Markets index, I favor iShares MSCI Emerging Markets Minimum Volatility (EEMV), which promises a gentler ride in this treacherous sector. Since its inception in late 2011, the ETF has handily beaten the MSCI index in each calendar year (including so far in 2014). During that stretch, it returned an annualized 7.3%—an average of 4.1 percentage points more than the MSCI index. The ETF invests in the 200 least-volatile stocks from the MSCI benchmark and employs a number of screens to ensure sector and geographic diversification. The portfolio overweights health care, consumer staples and utilities, but it doesn't look markedly different from the index—except that it's less volatile. Annual expenses are 0.25%. One of the most important lessons of investing is also one of hardest for many people to grasp: By the time you hear news about a company or a country, it's probably already reflected in stock prices. Yes, Europe and Japan are a mess, but investors know that. That's why their stocks are much cheaper than U.S. stocks based on earnings, sales and practically every other measure. What's more, a lot of companies in developed foreign lands derive most of their sales from the U.S. and healthier emerging nations. Advertisement So I'll take my developed-world foreign stocks straight up in 2015. Vanguard FTSE Developed Markets index (VEA) gives you the developed world, minus North America, for just 0.09% annually. Europe accounts for 60% of the fund's assets, with the rest in Asia. Japan, at 22% of assets, gets the largest weighting of any country; Great Britain is next, with 20%. Every portfolio needs a bond fund to provide ballast—even in 2015, when bond yields, which move in the opposite direction from bond prices, will probably rise. Fortunately for ETF investors, Fidelity, which does bonds well, recently launched several actively managed bond ETFs. My pick, Fidelity Total Bond (FBND), is run very similarly to Fidelity Total Bond Fund (FTBFX), a mutual fund that is a member of the Kiplinger 25. I think this ETF gives you decent current income while limiting interest-rate risk. If yields were to rise one percentage point, the ETF would lose 5.3% of its value. But the fund yields 3.1%, so the loss wouldn't be as painful as the decline in the share price suggests. The ETF's average credit quality is triple-B, and annual expenses are 0.45%. As far as allocation, an investor at least 10 years from retirement should put 30% in the bond ETF, 30% in Vanguard Dividend Appreciation, 25% in the Morningstar ETF, 10% in the Vanguard Developed Markets ETF and 5% in the emerging-markets ETF.
