What Is IGM? iShares Expanded Tech Sector ETF
Last updated July 2026
Short answer
IGM is iShares Expanded Tech Sector ETF, an ETF that tracks S&P North American Expanded Technology Sector Index at a 0.39% expense ratio. IGM tracks an expanded definition of technology. A strict sector fund such as VGT or XLK follows the GICS classification, which files Alphabet and Meta under communication services and Amazon under consumer discretionary, so those companies are excluded no matter how much of their business is technology. IGM's index deliberately reaches across those lines, which is why it holds NVIDIA, Apple, Broadcom and Microsoft alongside Alphabet and Meta. The trade-off is a higher expense ratio than the large sector funds and heavy concentration: the top ten positions are roughly half the fund.
IGM is issued by iShares and tracks S&P North American Expanded Technology Sector Index. It charges a 0.39% expense ratio, holds approximately $10.7B in assets under management, yields about 0.13%, and launched in 2001.

FAQ
What is IGM?
+
IGM is the iShares Expanded Tech Sector ETF. It tracks the S&P North American Expanded Technology Sector Index, holding US and Canadian technology companies plus the tech-adjacent communication services and consumer names that a strict sector classification excludes. It launched in 2001 and holds roughly $10.7 billion as of July 2026.
What is the difference between IGM and VGT?
+
Classification. VGT follows the GICS information technology sector, which files Alphabet and Meta under communication services, so VGT does not hold them. IGM's index deliberately reaches across those boundaries and does. If you want Alphabet and Meta inside your technology allocation rather than counted as media companies, that is the distinction. VGT is also considerably cheaper at 0.10% against IGM's 0.39%.
What is the difference between IGM and QQQ?
+
QQQ tracks the Nasdaq-100, which is defined by exchange listing rather than by sector, so it also holds large healthcare, consumer and industrial companies. IGM is a sector fund and holds technology and tech-adjacent names only. QQQ is cheaper at 0.20% and far larger. IGM is the more concentrated technology expression.
What does IGM hold?
+
Its largest positions as of July 2026 are NVIDIA at about 8%, Apple at 7.9%, Broadcom at 7.6% and Microsoft at 7.5%, followed by Micron, Alphabet, Meta, AMD and Intel. The top ten are roughly half the fund, so it is meaningfully concentrated despite holding a broader roster underneath.
What is IGM's expense ratio?
+
0.39% a year as of July 2026. That is high relative to the large technology sector funds, where VGT charges 0.10% and XLK 0.09%. On a $10,000 position the difference against VGT is roughly $29 a year, which compounds. The expanded classification is what you are paying the premium for.
Does IGM pay a dividend?
+
A small one, yielding about 0.13% as of July 2026. Technology companies generally retain earnings to reinvest rather than distribute them, so a technology fund's yield is minimal by construction. IGM is held for price return, not income.
Is IGM a good way to invest in AI?
+
It gives you concentrated exposure to the largest AI beneficiaries, since NVIDIA, Broadcom, Microsoft, Micron and AMD are all top holdings. It is not an AI fund, though: it also holds software, consumer technology and legacy names whose revenue has little to do with AI capex. A narrower AI or semiconductor fund expresses that thesis more directly. Walnut is not an investment adviser.
Am I already exposed to IGM's holdings?
+
Almost certainly. Its largest positions are also the largest weights in the S&P 500, so a broad index fund such as VOO already holds them heavily. Adding IGM concentrates that further rather than diversifying it. Check what you own through existing funds before adding a technology sector fund on top.
What are the risks of holding IGM?
+
Concentration is the main one: the top ten holdings are about half the fund, so a handful of companies drive returns. Beyond that, sector risk since everything moves together on the same technology cycle, valuation risk because the sector often trades at high multiples, and a higher expense ratio than comparable funds. Past performance does not indicate future results.
How do I compare IGM to similar ETFs?
+
Put a few fields side by side: the expense ratio (fees compound over decades), the index or strategy it tracks, the top holdings and how much they overlap with what you already own, the dividend yield, and the AUM, liquidity, and bid-ask spread that affect trading costs. For index funds, tracking error (how closely it follows its index) and tax efficiency matter too. IGM's figures are above; the full method is in Walnut's guide on how to compare ETFs.
