The Nasdaq-100 exchange traded fund is up 11% year to date to outperform the S&P 500. The technology-heavy ETF has rallied to the highest levels since the dot-com wreck.

The index is comprised of 100 tech stocks listed on the Nasdaq. Many small tech stocks are getting a boost from Facebook preparing an initial public offering, and some are wondering if the mania over the Facebook IPO is driving another bubble.

Since the Dec. 31, 2011 closing level of 2,6053.15 points, the NASDAQ Composite, a broader index, has rallied 11.54% to 2,905.66 points, a level unmatched since the dot-com age, reports David Huber for IRA.com.

SPDR Select Sector Technology ETF (NYSEArca: XLK) has gained about 5.7% year-to-date, marking a four-year high, reports Matt McCall for Seeking Alpha. Vanguard Information Technology (NYSEArca: VGT) has been able to outperform XLK, up 7.6%, possibly due to the more diversified portfolio. [NASDAQ-100 ETF Hits 11-Year High on Apple Blowout Earnings]

Healthy earnings reports from Apple Inc. (NASDAQ: APPL), and Netflix inc. (NASDAQ: NFLX) have rallied the broad market, and the tech sector.

Meanwhile, stocks and major indices took off after the Labor Department reported that the U.S. added 243,000 jobs in January, taking the unemployment rate down to 8.3%, the lowest since February 2009, reports Kate Gibson for MarketWatch.

“Everybody seems to be doubting the economic expansion, partly due to the European situation and partly due to consumer confidence. A lot of economists, analysts, and investors have short-changed the economic expansion we’re in now,” Brad Sorensen, director of market and sector analysis at Charles Schwab, said.

Future performance of the NASDAQ index for the remainder of the year is dependent upon major news coming from the Eurozone. The Federal Reserve’s decision to pump more liquidity into the U.S. economy, or not, will also be a factor. Certain analysts argue that equities could be on their way down after the latest rally, however, there are others that think the issues in Europe will push more investor assets into the U.S. market, reports The Telegraph.
