XLB

The Materials Select Sector SPDR Fund (XLB) is an exchange‑traded fund that provides exposure to U.S. large‑cap companies classified in the materials sector of the S&P 500. It tracks the Materials Select Sector Index, which includes firms engaged in chemicals, metals and mining, paper and forest products, containers and packaging, and construction materials, using a full‑replication, passive strategy. Because it is sector‑specific and non‑diversified, it is suitable for investors who want a targeted allocation to the U.S. materials industry for strategic or tactical positioning and who are comfortable with higher volatility relative to broad‑market funds.
