Friday's ETF Winners & Losers

Internet-related exchange-traded funds were among the top performers of Friday's session, as M&A activity boosted both the sector and the major averages.

Before the opening bell, Microsoft (MSFT Quote) said it will acquire Internet marketer aQuantive (AQNT Quote) for $6 billion in cash. The deal values shares of aQuantive at $66.50, an 83% premium over its last close.

aQuantive jumped more that 77% following the news, and other individual names were bidding higher as well. RealNetworks (RNWK Quote) was rising 2.8%, Akamai Technologies (AKAM Quote) added 2.6%, and Yahoo! (YHOO Quote), which Microsoft had pursued earlier this month, was up 2.1%.

The Internet Infrastructure HOLDRs (IIH Quote) was adding 13 cents, or 2.6%, to $5.13. The First Trust Dow Jones Internet Index (FDN Quote) was higher by 60 cents, or 2.5%, at $25.22.

Bundled securities tracking crude oil were also among the winners, as the front-month June contract continued its recent ascent. Crude was last up 25 cents to $65.11 a barrel, a gain of 4.4% for the week.

The Ultra Oil & Gas ProShares (DIG Quote) was adding $2.47, or 2.7%, to $94.08. The SPDR Oil & Gas Exploration & Production (XOP Quote) ETF was recently up 72 cents, or 1.6%, to $45.65. The PowerShares Dynamic Energy Exploration (PXE Quote) ETF gained 33 cents, or 1.5%, to $22.50.
