The State Street Technology Select Sector SPDR ETF (XLK), a popular investment vehicle, is frequently acquired by individuals aiming for a comprehensive stake in the technology sector. However, a detailed examination of its Securities and Exchange Commission (SEC) filings reveals that it does not include stock from prominent companies such as Alphabet, Amazon, Meta Platforms, Netflix, or Tesla. Conversely, a substantial proportion of the fund’s assets—specifically 35.87%—is allocated to just three entities: NVIDIA, Apple, and Microsoft. The top ten holdings collectively represent an even larger share, accounting for 64.45% of the fund.
This disparity between the perceived broad exposure and the actual concentrated holdings is a key limitation of XLK. The label “technology” associated with the fund covers a more specific and focused segment of the market than many investors might initially anticipate, highlighting the importance of understanding the underlying composition of such investment products.
The True Composition of Your Technology Fund
The latest SEC disclosure shows XLK maintaining 74 equity positions, collectively managing approximately $123.9 billion in net assets. NVIDIA stands as the largest holding at 14.65%, followed by Apple at 12.85%, and Microsoft contributing 8.38%. An additional trio of semiconductor firms each accounts for over 5% of the fund, with suppliers of chip equipment filling most of the remaining top ten spots. At the other end of the spectrum, numerous positions each constitute less than half a percent of the total assets.
Consequently, individuals expecting a diverse portfolio across the technological economy are instead invested in a fund heavily reliant on a select group of semiconductor and hardware manufacturers.
Why Key Tech Giants Are Excluded from XLK
XLK adheres to a sector index based on the Global Industry Classification Standard (GICS). This system assigns each publicly traded company to a single sector. Under GICS, Alphabet, Meta, and Netflix are categorized under Communication Services, while Amazon and Tesla fall into Consumer Discretionary. XLK's mandate restricts its holdings exclusively to companies classified within Information Technology.
The GICS framework classifies businesses according to their primary revenue generation methods. For instance, Alphabet and Meta primarily derive their income from advertising. Amazon's classification stems from its retail operations, and Tesla's from its vehicle manufacturing. This means that even highly technologically advanced businesses can be placed in different sectors.
This classification process is transparent and standard industry practice, with the fund strictly following its index. The challenge arises because many investors do not thoroughly review the sector definitions before investing in a sector-specific fund.
