Monday's ETF Winners & Losers

Bundled securities tracking the Internet sector were among the best performing exchange-traded funds Monday, as several individual names supported a jump in the tech sector.

Internet stocks were led higher by a 4.5% gain in Amazon.com (AMZN Quote). Elsewhere, VeriSign (VRSN Quote) was up 3.6%, Akamai Technologies (AKAM Quote) was higher by 2% and EarthLink (ELNK Quote) tacked on 1.6%.

The Internet Infrastructure HOLDRs (IIH Quote) was the best performer of the Internet ETFs, adding 10 cents, or 1.9%, to $5.21. The First Trust Dow Jones Internet Index (FDN Quote) was higher by 37 cents, or 1.5%, at $25.65. The Internet HOLDRs (HHH Quote) was climbing 79 cents, or 1.3%, at $61.54.

The Broadband HOLDRs (BDH Quote) ETF was another of the day's winners. Holdings Corning (GLW Quote), Nortel (NT Quote) and Broadcom (BRCM Quote) were all rising by 2% or more.

The Broadband HOLDRs was gaining 27 cents, or 1.7%, to $16.69.

The HealthShares Emerging Cancer (HHJ Quote) ETF was also up, thanks to a nearly 6% rise in shares of Dendreon (DNDN Quote).

The HealthShares Emerging Cancer ETF was recently up 33 cents, or 1.4%, to $23.18.

Crude had pushed to $65.38 before falling lower. Natural gas was also losing ground, down 8 cents to $7.86 per million British thermal units.
