The Internet Architecture HOLDRs ( IAH) was one of Thursday's best performing exchange-traded funds, as holdings IBM ( IBM) and Juniper Networks ( JNPR) jumped on better-than-expected earnings.

Following Thursday's close, IBM said it had a second-quarter profit of $1.50 a share, excluding a gain from the sale of its printing division, which beat the Thomson Financial average estimate by 3 cents a share. Shares of IBM were up more than 4%. Meanwhile, Juniper surged 12% after the networking company raised its sales forecast.

The Internet Architecture HOLDRs was recently up $1.37, or 2.7%, to $51.58.

The Software HOLDRs ( SWH) ETF also benefited from strong tech earnings results. German business software giant SAP ( SAP), which is one of the ETF's holdings, saw second-quarter revenue and operating income jump 10%, and shares rose 7%. The ETF was recently up $1.06, or 2.5%, to $42.94.

Bundled securities tracking utilities were also among the winners of the day. Among individual names, Exelon ( EXC), FirstEnergy ( FE) and FPL Group ( FPL) were higher by 1.7% or more.

The Ultra Utilities ProShares ( UPW) was rising $2.78, or 3.3%, to $85.98. The PowerShares FTSE RAFI Utilities ( PRFU) was adding $1.15, or 2%, to $60.07. The Utilities Select Sector SPDR ( XLU) gained 46 cents, or 1.1%, to $40.96.

On the losing side, health care-related bundled securities were losing ground, pressured by a second-quarter revenue miss by UnitedHealth Group ( UNH). The iShares Dow Jones U.S. Healthcare Provider ( IHF) was recently down 71 cents, or 1.2%, to $59.64. The Health Care Select Sector SPDR ( XLV) was losing 30 cents, or 0.8%, to $35.45.

While most tech earnings results were benefiting ETFs, concerns about online operations hampered eBay's ( EBAY) stock following its second-quarter earnings report. eBay, which is a holding of the Internet HOLDRs ( HHH), was recently down 1.5%. The ETF was shedding 65 cents, or 1.1%, to $60.90.
