For investors seeking exposure to the technology sector, the landscape often appears dominated by a handful of software and hardware behemoths. The iShares Expanded Tech Sector ETF (IGM) offers a distinct strategy by casting a wider net. With approximately $8 billion in assets under management, this fund provides a comprehensive gateway to North American technology and its adjacent industries, moving beyond a narrow definition of the sector.
Index Methodology and Portfolio Construction
The ETF tracks the S&P North American Expanded Technology Sector Index. This benchmark intentionally looks beyond traditional information technology companies to include holdings from communication services and consumer cyclical industries. By incorporating large-, mid-, and small-capitalization stocks, the index paints a more complete picture of the tech ecosystem than funds focused solely on mega-cap names.
A disciplined rebalancing process is key. The underlying index is reconstituted semi-annually and reweighted quarterly. Strict concentration limits are enforced: no single holding can exceed 8.5% of the portfolio. Furthermore, the combined weight of all positions individually exceeding 4.5% is capped at 45%. These rules are designed to mitigate excessive concentration risk, even though the fund’s top ten holdings—including heavyweights like NVIDIA, Apple, and Microsoft—currently account for a collective 53% of the portfolio.

Cost Efficiency and Competitive Positioning
The fund’s total expense ratio of 0.39% positions it as a cost-efficient option, sitting below the industry average for thematic ETFs. It occupies a unique space when compared to popular competitors. While ETFs such as the Technology Select Sector SPDR Fund (XLK) and the Vanguard Information Technology ETF (VGT) maintain a tight focus on the largest technology firms, IGM’s mandate allows for greater diversification across market capitalizations and related sectors. Investors desiring an even more uniform distribution might consider equal-weight alternatives like the Invesco S&P 500 Equal Weight Technology ETF (RYT).
Key Fund Details:
* Assets Under Management: ~$8 billion USD
* Total Expense Ratio (TER): 0.39%
* Number of Holdings: 290–296
* Technology Sector Allocation: ~81–82%
* Communication Services Allocation: ~17–18%
The product’s current assessment of four Morningstar stars and a Bronze rating highlights its established market position. With its blend of roughly 82% technology and 18% communication services stocks, the iShares Expanded Tech Sector ETF remains a strategic tool for investors aiming for broad-based exposure to the evolving tech sector, beyond just its most prominent constituents.
