NEW YORK ( TheStreet) -- Here are a number of opportunities for ETF investors this week.

iShares Dow Jones U.S. Pharmaceuticals Index Fund ( IHE)

The health care industry has been a choppy region of the market recently as companies mull ways to deal with the passage of Washington's sweeping reform bill. One subsector of this industry that has performed noticeably well however has been the pharmaceuticals.

Over the past 90 days, IHE has handlely outperformed ETFs designed to track other regions of the health care industry such as the iShares Dow Jones U.S. Healthcare Providers Index Fund ( IHF) and the iShares Dow Jones U.S. Medical Equipment Index Fund ( IHI).

Looking to this week, IHE will be an exciting fund to watch as a number of major holdings, including Bristol-Myers Squibb ( BMY), Merck ( MRK), Hospira ( HSP) and Mylan ( MYL) step up to report their performance over the past quarter.

ETFS Physical Precious Metals Basket Shares ( GLTR)

Precious metals remain a wildly popular region of the market as investors seek out ways to protect against broad market volatility. Late last week ETF Securities, a relative newcomer to the U.S. ETF industry, launched one of the more unique plays on this attractive asset class.

Whereas in the past, investors seeking physical exposure to precious metals could only pick them out one at a time using funds such as iShares Gold Shares ( IAU) and ETFS Physical Palladium Shares ( PALL), GLTR combines exposure to four metals: gold, silver, platinum, and palladium, under one roof.

While I foresee GLTR becoming a force to be reckoned with within the precious metals ETF arena, the fund is still new to the industry and therefore may take some time to gather steam.

iShares Dow Jones U.S. Aerospace & Defense Index Fund ( ITA)

Earnings season will once again thrust the aerospace and defense industry into the spotlight this week. Earnings reports from top ITA's holdings Boeing ( BA) , Lockheed Martin ( LMT) and United Technologies ( UTX) are out of the way, and this week a number of other major players within the fund's portfolio are slated to report their performance.

Investors with exposure to ITA should keep a close watch on the reports expected to come from General Dynamics ( GD), Raytheon ( RTN), Northrop Grumman ( NOC), Rockwell Collins ( COL) and L-3 Communications ( LLL).

iShares FTSE/Xinhua China 25 Index Fund ( FXI)

When it comes to gaining exposure to China, I typically advise investors to turn to the small- cap oriented Guggenheim China Small Cap ETF ( HAO) over the large cap, state-owned-enterprise dominated index underlying FXI. However, with half of this fund's index scheduled to report earnings this week, this China-focused ETF will be exciting to watch.

Economic headwinds facing the U.S. and Europe are causing investors to turn their attention overseas to opportunities present in the emerging markets. ETFs provide investors a unique opportunity to gain direct exposure to the economies of popular nations such as China, Brazil and India.

First Trust ISE Revere Natural Gas Index Fund ( FCG)

Oil industry heavyweights from around the world will dominate this week's earnings schedule but playing them with ETFs is a bit tricky.

Companies on board to report their earnings include Exxon Mobil ( XOM), ConocoPhillips ( COP), Chevron ( CVX), Hess ( HES), Total ( TOT), and Royal Dutch Shell ( RDS.A) (RDS.A).

Rather than choosing a broad energy fund such as iShares Dow Jones U.S. Energy Sector Index Fund ( IYE) to follow these earnings, First Trust's natural gas fund may be a bigger beneficiary. Oil giants are becoming increasingly involved with the natural gas industry and are therefore qualifying for positions within FCG's portfolio. XOM, COP, HES, TOT and RDS account for over 17% of the fund's total portfolio.
