Sector ETFs
0 stocks · Updated Mar 25, 2026
Sector ETFs allow investors to express targeted views on specific areas of the economy — technology, healthcare, financials, energy, and eight other GICS sectors — without selecting individual stocks. The SPDR Select Sector ETFs (XLK, XLV, XLF, etc.) are the most widely traded sector vehicles, used by both tactical asset allocators and long-term investors seeking sector tilts beyond market-cap-weighted index exposure.

Frequently Asked Questions
What are the 11 GICS sectors?
The Global Industry Classification Standard (GICS) defines 11 sectors: Information Technology, Healthcare, Financials, Consumer Discretionary, Industrials, Consumer Staples, Energy, Real Estate, Materials, Utilities, and Communication Services.
Why use sector ETFs instead of a total market ETF?
Sector ETFs enable tactical over or underweighting relative to market cap weights. If you believe tech will outperform (or underperform), a sector ETF provides targeted exposure. They also help manage concentration — overweighting defensive sectors heading into uncertainty.
What is sector rotation?
Sector rotation is the strategic movement of portfolio weight between sectors based on the economic cycle, interest rate outlook, or relative valuation. Different sectors outperform at different stages of the business cycle — this is the theoretical basis for tactical sector allocation.
Are equal-weighted sector ETFs better than cap-weighted?
Equal-weighted sector ETFs (RSP vs. SPY equivalent) reduce concentration in the largest companies. They have historically provided small cap tilt and slightly different return profiles. The best choice depends on your outlook for mega-caps versus the broader sector.
