NEW YORK ( TheStreet) -- Here are five ETFs to watch this week.

First Trust Dow Jones Internet Index Fund ( FDN)

More social media firms are preparing to follow in the footsteps of LinkedIn ( LNKD) and go public. Late last week the chatter centered on Groupon and Pandora after the two had announced their IPO valuations.

Facebook and Zynga were also in the news late last week following reports that Will Danoff, the manager of the Fidelity Contrafund ( FCNTX), had acquired a stake in the two firms.

As I've explained in the past, it's best to be on the sidelines with respect to these social media companies. FDN, which provides investors with exposure to well-established online entities, will likely benefit from the attention that has been focused on the Internet as a result of the chatter generated by these social media companies.

iShares Dow Jones Select Dividend Index Fund ( DVY)

The recent round of rough economic data has begun to take a toll on investors. While the headwinds may seem daunting, I urge investors to avoid fleeing these markets and take appropriate steps to weather the turmoil.

DVY boasts a number of qualities that make it well suited for the road ahead. On top of providing investors with exposure to a vast collection of top dividend-paying companies, the fund's sector breakdown is strongly weighted towards defensive names. Together, utilities, consumer staples and health care comprise over half of the fund's total assets.

SPDR S&P Semiconductor ETF ( XSD)

On Thursday, National Semiconductor ( NSM) is slated to report its earnings. In addition to its quarterly report, however, it will also be interesting to see what the firm has to say about its acquisition by Texas Instruments ( TXN) for $6.5 billion.

Investors looking for the most concentrated exposure to NSM should turn to XSD. The fund lists the firm as its top holding, accounting for over 3% of its index.

iShares Barclays 20+ Year Treasury Bond Fund ( TLT)

Government-sponsored debt fell under pressure last week after Moody's issued a warning of a possible downgrade. The ratings agency said that unless progress was made in the ongoing debt discussions, the U.S. could see its credit rating dip from the pristine Aaa. The firm warned the downgrade could come as a soon as next month.
