The technology sector is currently dominated by the artificial intelligence (AI) gold rush, which is generating significant investor excitement and driving historic market performance. The meteoric rise of companies like NVIDIA (NASDAQ: NVDA) has demonstrated the immense potential of this technological shift, leaving many investors with a critical question: How can one invest in an entire revolution without accepting the high-risk gamble of picking individual stocks?
As investors seek strategies to capitalize on this trend, thematic exchange-traded funds (ETFs) have emerged as popular solutions. The iShares Expanded Tech Sector ETF (NYSEARCA: IGM) has gained considerable traction by offering a unique and targeted approach to owning the companies at the forefront of AI innovation.
The Expanded Advantage in IGM's Portfolio
A look under the hood of IGM reveals a portfolio built with a distinct and aggressive philosophy. The fund's strategy is to track the S&P North American Expanded Technology Sector Index, and that single word, expanded, is key to its unique structure.
Unlike more traditional tech funds that strictly adhere to the information technology sector (IT), IGM’s mandate allows it to include influential, tech-related companies from the communication services (which includes media, entertainment, and interactive services) and consumer discretionary sectors.
This modern approach recognizes that technological influence transcends rigid sector definitions. It allows for the strategic inclusion of powerhouse firms like Meta Platforms (NASDAQ: META) and Netflix (NASDAQ: NFLX), which are central to digital content and media but often excluded from more narrowly focused tech ETFs.
The result is a non-diversified portfolio intentionally concentrated in the market's most dominant names. This is not a broad, passive index fund; it is a high-conviction vehicle where the performance is directly tied to the collective success of a select group of market leaders.
The fund’s composition is a window into this focused approach. The portfolio is dominated by companies that are building the AI future, with significant positions in Microsoft (NASDAQ: MSFT), whose cloud and software suite are deeply integrated with AI; Nvidia, the undisputed leader in AI chip manufacturing; and Meta Platforms, a pioneer in developing large language models.
These are complemented by foundational innovators like Broadcom (NASDAQ: AVGO) and Apple (NASDAQ: AAPL). The fund also provides meaningful exposure to high-growth enterprise software through names like Palantir Technologies (NASDAQ: PLTR), a pure-play AI platform that has captured significant investor attention.
This deliberate concentration means that when these leaders perform well, the impact on IGM's value can be substantial.
Strong Returns, Bullish Sentiment
This focused strategy has translated into strong market momentum and tangible results. The fund’s performance serves as a clear indicator of its potential, delivering a total gain of over 60% in the 2023 bull market and continuing with a strong increase of approximately 14.5% in the second quarter of 2025. This level of return underscores the fund’s aggressive positioning.
The fund's inherent volatility is quantified by its beta of 1.26. This metric suggests that IGM has historically been about 26% more volatile than the S&P 500. For investors, this means the fund tends to amplify market movements, offering the potential for outsized returns in bullish environments while also carrying a higher degree of risk during downturns.
Recent investor behavior indicates a growing conviction in IGM's strategy.
The fund has experienced consistent net inflows, attracting approximately $250 million in new assets during the second quarter of 2025, bringing its total assets under management (AUM) to roughly $6.4 billion.
At the same time, data shows a sharp decline in short interest, which is basically the number of bets made that the fund's price will fall. This combination of new money coming in and bearish bets declining suggests that market sentiment is firmly positive, which can serve as a strong technical tailwind for the fund's price.
A High-Conviction Tool for the Tech Bull
The iShares Expanded Tech Sector ETF is not a passive, broad-market fund for every investor. It is a targeted and aggressive instrument designed for those with a high tolerance for volatility and a strong, long-term bullish outlook on the future of North American technology, particularly in artificial intelligence.
Its thoughtful, expanded-sector approach provides a unique method for capturing the influence of tech's biggest names.
While recent changes to the fund's management team are notable, its core strategy remains unchanged. It is designed to passively track its underlying index.
This ensures a level of strategic continuity that is less dependent on any single manager. For investors looking for a powerful tool to execute a high-conviction thesis on the AI revolution, IGM presents a compelling case, with a moderate 0.41% expense ratio for its specialized exposure.
