This Week's ETF Winners & Losers

Exchange-traded funds tracking tech shares were among the biggest winners for the week as several big names delivered solid first-quarter numbers.

The Internet HOLDRs HHH ETF gained 4.5% for the week, and the Internet Architecture HOLDRs IAH surged 6.7%. The Semiconductor HOLDRs SMH rose 2.9%, and the iShares S&P GSTI Semiconductor IGW climbed 3.9%.

The upward momentum came as search giant Google GOOG helped spark a massive rally Friday and chipmaker Intel INTC did the same a couple of days earlier, both thanks to better-than-expected earnings. Google jumped 17.9% for the week as Intel tacked on 6.2%.

IBM IBM, meanwhile, helped the Dow hold its own on Thursday as the computer maker topped expectations with a leaping quarterly profit. For the week, the stock was up 7.2%.

Also gaining ground this week were ETFs tracking financial stocks. The week saw mixed results, but some big names, most notably, Citigroup C and JPMorgan Chase JPM, allayed investors' fears with first-quarter results that weren't thoroughly dismal. Citi missed the average Wall Street estimate but its first-quarter writedowns weren't nearly as bad as some were predicting, and JPMorgan's sliding profit came in above the consensus. Shares added 7.5% and 7.6%, respectively, over the past five sessions.

At the same time, the Financial Select Sector SPDR XLF, Ultra Financials ProShares UYG, iShares Dow Jones U.S. Financial Sector IYF ETF and iShares S&P Global Financials IXG all advanced between 4.7% and 10.6%.

Also, in a week that saw crude oil hitting record intraday highs every day, the Oil Services HOLDRs OIH jumped 10.9%, the Ultra Oil & Gas ProShares DIG rocketed 16.1%, the United States Oil USO climbed 5.9%, and the Energy Select Sector SPDR XLE ramped up 8%.

On the flip side, bundled securities tracking gold slipped as gold futures sank for the week.

The PowerShares DB Gold DGL, the iShares COMEX Gold Trust IAU and the streetTRACKS Gold Shares GLD funds were all down 0.7% or more.

Finally, ETFs tracking Treasury securities faltered as investors shifted their money out of the safe haven of government bonds, having regained at least some of their confidence in equities.

The iShares Lehman 20+ Year Treasury Bond TLT fund was off 3.3% for the week, the iShares Lehman 10-20 Year Treasury Bond TLH surrendered 2.4%, and the iShares Lehman 7-10 Year Treasury IEF was down 1.7%.
