Wall Street bets on chip boom are getting more concentrated, and it could be good thing for investors

The semiconductor sector is experiencing a 'super cycle' fueled by the AI boom and Nvidia's market leadership, with traditional market-cap weighted ETFs like VanEck's SMH delivering nearly 30% YTD gains. Amid concerns over concentration, new ETF strategies are emerging to offer diversified exposure, including equal-weighted funds such as SPDR's XSD (up ~26% YTD with Nvidia <3% weight), momentum/value-based approaches like Invesco's PSI, and fabless-focused products like VanEck's SMHX. These options provide institutional investors with varied risk profiles to capitalize on the sustained growth in the chip industry.

Analysis

The semiconductor sector is experiencing a period of significant outperformance, driven by the artificial intelligence boom and the ascent of Nvidia to over a $4 trillion market capitalization. This is evidenced by the VanEck Semiconductor ETF (SMH), which has returned nearly 30% year-to-date, more than double the approximate 13% gain of the SPDR S&P 500 ETF (SPY). However, this performance has led to notable concentration risk, with Nvidia alone constituting over 20% of SMH and roughly 8% of the S&P 500. In response, the market is offering alternative ETF structures to manage this exposure. The SPDR S&P Semiconductor ETF (XSD) utilizes an equal-weighting methodology, reducing Nvidia's influence to under 3% and providing balanced exposure to smaller firms like Astera Labs and Credo Technology, while still achieving a strong 26% YTD return. Other specialized vehicles are also gaining traction, including the Invesco Semiconductors ETF (PSI), which employs a custom index based on momentum and value factors, and the new VanEck Fabless Semiconductor ETF (SMHX), which targets chip designers and includes thematic plays on power efficiency such as Monolithic Power. The prevailing sentiment, articulated by industry experts describing the current environment as a "super cycle" in its "very early innings," suggests sustained investor interest and the strategic importance of choosing an appropriate vehicle to align with specific risk and concentration preferences.

Key Decisions for Investors

• For investors seeking direct, market-cap weighted exposure to AI leaders and who are comfortable with high single-stock concentration, the VanEck Semiconductor ETF (SMH) remains a primary vehicle given its sector-leading 30% year-to-date performance.
• To mitigate concentration risk from Nvidia while maintaining robust exposure to the semiconductor theme, consider the equal-weighted SPDR S&P Semiconductor ETF (XSD), which has also delivered strong returns (~26% YTD) with more diversified holdings.
• Investors with a more aggressive or tactical mandate should evaluate specialized funds like the factor-based Invesco Semiconductors ETF (PSI) or the thematic VanEck Fabless Semiconductor ETF (SMHX) to gain targeted exposure to specific industry sub-segments like chip design or momentum-driven names.
• Monitor relative fund flows and performance between market-cap (SMH) and equal-weight (XSD) ETFs as a key indicator of shifting institutional sentiment towards either embracing concentration in mega-cap winners or seeking broader diversification across the semiconductor value chain.
