What Is ETF Sector Weighting?
ETF sector weighting shows how an exchange-traded fund distributes its assets across different market sectors such as Technology, Healthcare, Financial Services, and Energy. Each sector's weight represents the percentage of the fund's total assets invested in companies within that sector. Understanding sector weightings is essential for investors who want to know their true exposure to specific industries, avoid unintended concentration risk, and build a diversified portfolio. Our free ETF Sector Weighting tool lets you look up the sector allocation of any ETF instantly.

Why ETF Sector Weighting Matters
Understand True Exposure
An ETF's name alone doesn't tell the full story. SPY may be an S&P 500 fund, but over 30% of its weight can be in Technology. Knowing sector weights helps you understand what you're actually investing in.
Avoid Concentration Risk
If you hold multiple ETFs with heavy Technology exposure, your portfolio may be more concentrated than you think. Checking sector weights across your ETFs prevents unintended overlap.
Sector Rotation Strategy
Different sectors outperform at different stages of the economic cycle. By comparing ETF sector weights, you can tilt your portfolio toward sectors poised for growth.
