NEW YORK ( TheStreet) -- Here are five ETFs to watch this week.Industrial Select Sector SPDR ( XLI) The industrials have run into trouble the past few months as investors have begun to question the strength of the global economy. Since its July breakdown, shares of XLI have struggled to recover lost ground, as the fund has jockeyed back and forth along a generally sideways path. During the middle and latter half of the week, investors can expect to uncover important clues regarding the current state and future prospects for this sector. Sprinkled within the busy earnings calendar are names including United Technologies ( UTX), General Electric ( GE), Honeywell ( HON) and Union Pacific ( UNP). All of these firms are among XLI's top holdings. Fans of the transportation sector will want to keep close watch on this week's earnings. Aside from UNP, fellow railroad goliaths including CSX ( CSX) and Kansas City Southern ( KSU) will be on tap. Southwest Airlines ( LUV) will also report. Investors looking for dedicated exposure to the transportation sector can turn to the iShares Dow Jones Transportation Average Index Fund ( IYT). iShares Dow Jones U.S. Telecommunications Sector Index Fund ( IYZ) Although only two of IYZ's top holdings are up for earnings this week, the respective performances from AT&T ( T) and Verizon Communications ( VZ) (VZ) will have heavily influence the fund's action. Telecommunication ETFs like IYZ are designed to provide investors with expansive exposure to this market segment. However given the dominance of AT&T and Verizon, many of these products dedicate the lion's share of their portfolio to these two companies. In the case of IYZ, nearly one-third of the fund's portfolio is dominated by the two companies. IYZ will be interesting to watch as these two telecom goliaths report their quarterly results. Investors looking to get in on the action need to be cautious. In order to protect against the risks associated with a top-heavy product like IYZ, exposure must be kept small and focused. iShares Dow Jones U.S. Technology Sector Index Fund ( IYW) Google's strong earnings performance set the stage for what could be an impressive showing from the technology sector over the next few weeks. In the days ahead, investors will have their sights set on companies such as Apple ( AAPL), Intel ( INTC), EMC ( EMC), and Microsoft ( MSFT) as they prepare to report their own earnings numbers and outlooks. International Business Machines ( IBM) will kick off this week's tech earnings today.
