A Capped index for Basic Materials Companies
IYM tracks the Russell 1000 Basic Materials RIC 22.5/45 Capped Index. The benchmark is a capped subset of a large- and mid-cap US Equity universe. Its industry definition directs the portfolio towards businesses involved in basic materials. Issuer-weight constraints shape the index, while the underlying companies retain exposure to their own products and markets.
The fund uses representative sampling, selecting investments intended to resemble the benchmark’s overall characteristics. It may therefore hold a different collection of securities from the index while seeking a similar Investment profile.
Portfolio Composition and Exposure
IYM reported 40 holdings as of 30 October 2026. Its allocation by Market Value included INDUSTRIAL GASES at 26.09%, Gold at 16.82% and Specialty Chemicals at 14.07% as of 30 October 2026.
The fact sheet dated 30 September 2026 identified holdings including Linde plc at 19.75%, Newmont at 11.02% and Freeport-McMoRan Inc. at 9.11%. These position weights refer to that reporting date and can change as the portfolio and market values evolve.
The same fact sheet reported a P/E ratio of 27.00x and a P/B ratio of 3.68x. These valuation measures complement the holdings information with Earnings and book-value characteristics associated with the equity portfolio.
Fees and Distribution Policy
The published expense ratio is 0.37%. Distributions are scheduled quarterly.
The 30-day SEC Yield was 1.19% as of 30 September 2026. This standardised income measure reflects the fund’s recent income after expenses; it is separate from changes in the market value of its shares.
The prospectus notes that brokerage commissions and other intermediary charges may apply separately. Fund shares trade at market prices, which can differ from NAV, so the stated NAV does not establish the price of every exchange transaction.
Key Insights
Commodity prices, exchange rates, Demand and government regulation can affect materials businesses. The fund holds company equities, so operating conditions and issuer-specific developments matter alongside movements in raw material markets.
