• These ETFs cover the technology sector, including software, semiconductors (chips), enterprise hardware and consumer gadgets. We've included Internet ETFs here as well, although they're a hybrid of media and technology.
• Sector ETFs come in four levels of granularity: (1) global, (2) US or international, (3) the main industry sub-groups that comprise the sector, and (4) narrower groups of companies within the sector.
• Specialty ETFs are also available for the technology sector, including leveraged, inverse, quant strategy, fundamental index and equal weighted ETFs. These ETFs are explained in their own sections of the ETF Finder.

• Sector ETFs tend to be more concentrated than broad index ETFs. That means they can be more volatile, and can involve greater long term risk if the largest stocks in the ETF performs poorly.
• Sector ETFs tend to have higher expense ratios than broader index ETFs.
• Merrill Lynch HOLDRs are fixed baskets of stocks that become less and less representative of their sectors over time. The Internet HOLDRs ETF, for example, doesn't include Google.
