USCF Daily Target 2X Copper Index ETF

The USCF Daily Target 2X Copper Index ETF (CPXR) seeks 200% of the single-day return of the SummerHaven Copper Index, the same benchmark CPER tracks at 1x. Launched in January 2025, CPXR is a registered investment company (1099 tax reporting) rather than a commodity pool, despite its futures-based strategy.

CPXR is a short-term trading tool, not a buy-and-hold copper investment. Its daily-reset structure means returns compound daily: over periods longer than one day, its performance will very likely diverge — sometimes sharply, and potentially in the opposite direction — from 2x the underlying index return, especially in volatile markets. The fund itself warns investors could lose their full principal in a single day. It is included here for completeness given it is a real, US-listed, exchange-traded copper product, but it is not comparable to the other four equity/futures funds on this list.

Note on holdings weights: because CPXR uses leveraged futures and collateral positions to target 2x daily exposure, its individual holdings weights sum to well over 100% of net assets — this is expected for a leveraged fund and does not indicate an error.

Themes Copper Miners ETF

The Themes Copper Miners ETF (COPA) tracks the BITA Global Copper Mining Select Index, a basket of companies engaged in copper mining, exploration and refining. Holdings span major diversified producers such as Freeport-McMoRan, Glencore and BHP alongside mid-cap pure plays across the US, UK, Canada, Australia and China.

iPath Carbon ETN

GRN is an Exchange Traded Note that links its return to the Barclays Global Carbon II TR USD Index, providing exposure to carbon credit futures from the EU ETS and Kyoto Protocol mechanisms.

ProShares S&P Kensho Cleantech ETF

CTEX tracks the S&P Kensho Cleantech Index, measuring U.S.-listed companies developing technologies enabling clean energy generation including solar, wind, geothermal, hydrogen, and hydroelectric.

The roughly 45-stock portfolio was weighted toward fuel cell, energy storage and solar equipment names as of July 2026, led by FuelCell Energy, Bloom Energy and Shoals. The fund is small, with roughly $7M in assets as of July 2026.

Defiance Daily Target 2X Long Copper Miners ETF

The Defiance Daily Target 2X Long Copper Miners ETF (COPZ) seeks 200% of the single-day price performance of the Global X Copper Miners ETF (COPX), before fees and expenses, using total-return swap agreements held against cash collateral.

COPZ is a short-term trading tool, not a buy-and-hold copper investment. Its daily-reset structure means returns compound daily: over periods longer than one day its performance can diverge substantially, and potentially in the opposite direction, from 2x the underlying return. It is included here for completeness as a real, US-listed exchange-traded copper product, but it is not comparable to the equity and futures funds on this list. It launched in February 2026 and held roughly $6M in assets as of July 2026. Note on holdings weights: swap and collateral positions sum to well over 100% of net assets, which is expected for a leveraged fund.

iShares Environmental Infrastructure and Industrials ETF

EFRA tracks the FTSE Green Revenues Select Infrastructure and Industrials Index, holding companies providing infrastructure and industrial solutions for energy efficiency, emissions mitigation, and resource optimization.

With nearly half its portfolio in foreign equities and 53 holdings, EFRA provides diversified exposure to environmental infrastructure including water treatment, waste management, and efficiency technologies.

WisdomTree Efficient Rare Earth Plus Strategic Metals Fund

The WisdomTree Efficient Rare Earth Plus Strategic Metals Fund (WDIG) uses a capital-efficient structure: for each $100 invested, roughly $90 goes to rare-earth and strategic-metals mining equities and roughly $90 of notional exposure to a basket of listed metals futures, collateralized by short-term US Treasury holdings. Launched on Cboe in May 2026, it is the first US ETF to pair rare-earth mining equities with a metals futures overlay in a single wrapper.

Because of the dual equity-plus-futures stack, WDIG's behaviour differs from the plain equity funds on this list, and its holdings weights reflect both legs. Assets were roughly $5M as of July 2026, two months after launch.

Roundhill Uranium ETF

The Roundhill Uranium ETF (UX) is an actively managed fund that seeks exposure to the spot price of physical uranium (U3O8) rather than uranium mining equities. It does not hold physical uranium directly: exposure comes through swap agreements linked to the Sprott Physical Uranium Trust and Yellow Cake plc, held against Treasury bill collateral, alongside direct trust units. It launched in January 2025 on Cboe BZX.

UX is the only fund on this list targeting the uranium commodity price itself rather than miners or the nuclear value chain. Note on holdings weights: because the fund combines collateral and swap positions, individual weights sum to well over 100% of net assets, which is expected for a swap-based fund and does not indicate an error. Assets were roughly $4M as of July 2026.

Themes Lithium & Battery Metal Miners ETF

The Themes Lithium & Battery Metal Miners ETF (LIMI) tracks the BITA Global Lithium and Battery Metals Select Index, covering companies involved in mining, exploration and refining of lithium and other battery metals. The portfolio mixes Australian and US lithium producers such as PLS Group and Albemarle with Chinese cathode-material and cobalt names.

LIMI is one of the smallest funds in the category, with roughly $2M in assets as of July 2026, at a 0.35% expense ratio.

USCF Sustainable Battery Metals Fund

ZSB is an actively managed fund using proprietary quantitative methodology to invest in metals derivatives tied to electrification metals essential for battery and sustainable energy infrastructure.

Unique among offerings, ZSB combines commodity/futures exposure with equities and incorporates carbon offsets, representing a sophisticated approach to battery metals exposure.

Tortoise Nuclear Renaissance ETF

The Tortoise Nuclear Renaissance ETF (TNUK) is an actively managed equity fund covering the global nuclear energy industry across uranium mining, the fuel cycle, reactor developers and component suppliers, and nuclear power operators. The manager allocates dynamically across these segments rather than tracking an index, with holdings spanning US, UK, Canadian and Korean listed companies.

Launched in December 2025, TNUK is the smallest fund on this list, with roughly $1M in assets as of July 2026.
