The universe of exchange-traded funds just keeps getting bigger and bigger. With much more than a thousand ETFs in existence -- and more coming out every day -- it's almost impossible to keep track of all of them.
Fortunately, out of all those ETFs, only a few really warrant a lot of attention in the current market environment. So without any further ado, let's take a look at four ETFs that smart investors are watching right now.
United States Natural Gas (NYSE: UNG)
Natural gas prices have been front-and-center of every discussion of the energy industry over the past several months. With natural gas falling below the $2 level before bouncing back in recent days, gas producers have had a tough time making ends meet, while gas consumers like electric utilities couldn't be happier. But with more producers choosing to stop producing at a loss, prices seem to be looking to find a floor from which to stage a potential bounce-back.
The United States Natural Gas ETF lets short-term traders take advantage of moves in the price of natural gas futures contracts. But for longer-term investors, the fund suffers a fatal flaw -- a quirk in the structure of the gas futures markets has produced much larger losses than the drop in spot gas prices would suggest. This ETF is only a good bull play if you expect a quick turnaround for natural gas.
PowerShares Financial Preferred (NYSE: PGF)
Preferred stocks differ from common stocks in that preferreds tend to pay higher dividends but provide more share price stability. That's appealing to conservative investors, especially those who don't need capital appreciation from their portfolios.
The broader preferred-stock ETF iShares S&P U.S. Preferred (NYSE: PFF) has some non-financial issues within its portfolio. But for the most part, the majority of preferred offerings are financials, and so sticking with the niche focus of the PowerShares ETF is just as realistic a picture on the market. Again, investing in the ETF is purely optional, but as a barometer on the true health of financial institutions, the PowerShares ETF gives you a worthy gauge.
Direxion Daily Small Cap Bear 3x (NYSE: TZA)
In general, investing in leveraged ETFs is fraught with peril. Long-term investors will almost inevitably find their returns eroded by the daily tracking structure of the derivatives that these ETFs own, turning even correct predictions about the future direction of a market into unprofitable investments.
But watching leveraged ETFs can be very lucrative. As a gauge of retail investor sentiment, it's useful to watch volume on bull and bear ETFs -- especially ones in less-followed markets, like this small-cap-oriented fund. When big bearish bets come into play, you can anticipate a big move -- although reasonable people may disagree about whether going against the tide or with the herd is the better strategy.
iPath S&P 500 VIX Short-Term Futures (NYSE: VXX)
Volatility is a core element of investing. But investing in volatility has come into vogue recently, as traders seek to cash in on changing expectations of how choppy the markets will be in the near future.
Like United States Natural Gas, the iPath ETN is another example of how derivative-owning exchange-traded products can diverge from the spot values of the indexes they track. The iPath ETN may give you an easy way to bet on short-term volatility changes, but long-term investors should steer clear.
