FTXL vs SOXX: Weighing Factor-Based and Cap-Weighted Semiconductor Strategies
Key Takeaways
- First Trust Nasdaq Semiconductor ETF (FTXL) employs a factor-based smart beta approach that selects and weights semiconductor stocks using liquidity, value, volatility, and growth metrics, resulting in approximately 35 holdings and an expense ratio of 0.60%.
- iShares Semiconductor ETF (SOXX) follows a market-capitalization-weighted methodology with concentration caps, tracking the NYSE Semiconductor Index with 30 holdings and a lower expense ratio of 0.35%.
- Both ETFs provide concentrated exposure to the U.S. semiconductor sector but differ in construction: FTXL incorporates active factor tilts while SOXX maintains a more traditional cap-weighted structure with liquidity and investability screens.
- FTXL offers slightly broader holdings diversity within the sector, whereas SOXX delivers higher liquidity and lower costs, potentially suiting investors prioritizing efficiency and scale.
- Expense ratio differences create a structural cost advantage for SOXX over long holding periods, while FTXL’s factor methodology may appeal to those seeking exposure to specific fundamental characteristics.
- Both funds target similar thematic goals in semiconductors but position investors differently within sector rotation and earnings cycles due to their distinct index methodologies.
Why Semiconductor ETFs Remain Relevant
The semiconductor industry continues to drive progress in artificial intelligence, computing, and electronics. FTXL and SOXX both target this space, yet they rely on distinct indexing methods. They are not interchangeable but instead offer alternative ways to gain equity exposure, each shaped by its own risk and return characteristics.
FTXL: A Factor-Driven Approach
FTXL tracks the Nasdaq U.S. Smart Semiconductor Index. It applies a rules-based selection of liquid U.S. semiconductor companies and weights them by factors such as value, volatility, and growth. The ETF holds roughly 35 securities at an expense ratio of 0.60%. Typical top holdings include Micron Technology, Intel, Marvell Technology, Advanced Micro Devices, and Qualcomm. Nearly all assets sit in technology, with emphasis on electronic components and manufacturing. The fund is non-diversified and rebalances at intervals to preserve its factor exposures. I also checked this using Tickeron’s AI Screener to see how the stock compares to others in the industry.
SOXX: Traditional Market-Cap Weighting
SOXX follows the NYSE Semiconductor Index with a market-capitalization-weighted method that includes caps on individual holdings. It contains 30 securities, carries a 0.35% expense ratio, and incorporates liquidity and investability screens. Common holdings feature NVIDIA, Advanced Micro Devices, Micron Technology, Broadcom, and Intel. Exposure stays centered on semiconductor designers, manufacturers, and equipment makers. The fund uses sampling to match the index and rebalances quarterly after annual reconstitution, producing a more concentrated profile than factor-adjusted peers.
Sector Backdrop and Key Influences
Demand for semiconductors stays supported by AI infrastructure needs, data center growth, and advanced computing. Interest rate expectations, supply chain shifts, and capital spending patterns among large technology firms affect both ETFs. Export controls and trade policy add layers of volatility, yet the long-term structural rise in chip demand keeps investor interest steady across cycles.
Performance Patterns and Positioning Differences
Both ETFs respond to semiconductor earnings and technology sector rotations. SOXX’s cap-weighted design can magnify moves in the largest names when momentum favors leading chipmakers. FTXL’s factor tilts may shift relative results by favoring stocks with attractive valuations or growth traits, which can temper volatility in some settings. From what I see, SOXX generally provides stronger liquidity for sizable trades, while FTXL supplies an alternative weighting that can react differently to rate sentiment or input cost changes.
