Educational purposes only. ## Quick Answer The MicroSectors Oil & Gas Exp. & Prod. 3x Leveraged ETN (OILU) is a leveraged ETN with $0.03B in assets under management and an expense ratio of 0.95%. OILU provides a bullish, 3x leveraged exposure to a concentrated portfolio of U.S. companies involved in oil and gas exploration and production. As an ETN, OILU exposes investors to the credit risk of the issuer, REX Microsectors, and its leveraged nature makes it suitable only for short-term trading strategies. ## Fund Snapshot - **Fund Name:** MicroSectors Oil & Gas Exp. & Prod. 3x Leveraged ETN - **Symbol:** OILU - **Asset Class:** Equity - **Issuer:** REX Microsectors - **Domicile:** US - **Expense Ratio:** 0.95% - **NAV:** $21.99 - **AUM:** $33.55M - **Inception Date:** 2021-11-09 - **Holdings Count:** 1 - **Dividend Yield:** 0.00% - **Beta:** 1.10 ## About MicroSectors Oil & Gas Exp. & Prod. 3x Leveraged ETN OILU is an aggressive and bullish one-day bet on a concentrated portfolio of US companies in the oil and gas exploration and production industry. The index has a slightly broader scope of the industry as it covers three segments: (i) integrated oil and gas exploration and production, (ii) upstream energy, and (iii) downstream and midstream energy. The index does not include MLPs. It selects the top 25 stocks by market-cap and weights the resulting portfolio by the minimum average daily value traded over 1-month and 6-months. The following weights are assigned per bucket: 30% for oil and gas exploration and production, 50% for upstream, and 20% for downstream and midstream. As a geared product, OILU is only designed as a short-term trading tool. Long-term returns could materially differ from those of the index due to daily compounding. Additionally, since the fund uses an ETN structure, investors assume the credit risk of the issuer. ## Investment Strategy OILU offers a leveraged investment strategy, seeking to deliver three times the daily performance of the Solactive MicroSectors U.S. Big Oil Index. This index focuses on the top 25 U.S.-listed companies in the oil and gas industry, encompassing integrated oil and gas exploration and production, upstream energy, and downstream and midstream energy segments, excluding MLPs. The index components are weighted based on a combination of market capitalization and average daily trading value, with specific allocations of 30% to oil and gas exploration and production, 50% to upstream, and 20% to downstream and midstream. With its leveraged exposure, OILU is designed for sophisticated investors seeking short-term tactical opportunities in the energy sector. The fund's top holdings include Exxon Mobil Corp (15.11%), Chevron Corp (15.00%), and ConocoPhillips (6.65%), reflecting its concentration in major oil and gas companies. Due to the effects of compounding, long-term returns can deviate significantly from the index's performance. ## Risk Profile OILU presents several risks inherent to its structure and investment strategy. As a leveraged ETN, it is subject to the credit risk of the issuer, REX Microsectors. The fund's 3x leverage amplifies both gains and losses, making it highly volatile and unsuitable for risk-averse investors. The concentration of holdings in the energy sector (100.0%) exposes the fund to sector-specific risks, such as fluctuations in oil prices and changes in energy demand. With a 3-year beta of 1.10, OILU exhibits higher volatility compared to the broader market. The high expense ratio of 0.95% can further erode returns, especially if held for extended periods. The fund's design as a short-term trading tool means that long-term investors may experience returns that differ significantly from the underlying index due to daily compounding. ## Top Holdings - [Exxon Mobil Corp (XOM)](https://www.stockexpertai.com/stock/xom) — **Weight:** 15.11% - [Chevron Corp (CVX)](https://www.stockexpertai.com/stock/cvx) — **Weight:** 15.00% - [ConocoPhillips (COP)](https://www.stockexpertai.com/stock/cop) — **Weight:** 6.65% - [SLB Ltd (SLB)](https://www.stockexpertai.com/stock/slb) — **Weight:** 6.28% - [EQT Corp (EQT)](https://www.stockexpertai.com/stock/eqt) — **Weight:** 4.46% - [Occidental Petroleum Corp (OXY)](https://www.stockexpertai.com/stock/oxy) — **Weight:** 4.35% - [EOG Resources Inc (EOG)](https://www.stockexpertai.com/stock/eog) — **Weight:** 4.05% - [Baker Hughes Co Class A (BKR)](https://www.stockexpertai.com/stock/bkr) — **Weight:** 3.61% - [Valero Energy Corp (VLO)](https://www.stockexpertai.com/stock/vlo) — **Weight:** 3.55% - [Expand Energy Corp Ordinary Shares - New (EXE)](https://www.stockexpertai.com/stock/exe) — **Weight:** 3.42% ## Sector Allocation - Energy: 100.0% ## Country Allocation - Other: 100.0% ## Market Context OILU's performance is closely tied to the dynamics of the oil and gas market. As a leveraged product, it is particularly sensitive to short-term price movements in the energy sector. The fund may appeal to traders seeking to capitalize on bullish trends in oil prices or specific developments within the oil and gas industry. However, investors should be aware of the risks associated with leveraged products, especially in volatile market conditions. The competitive landscape includes other energy-focused ETFs, but few offer the same level of leveraged exposure as OILU. Macroeconomic factors, such as global economic growth, geopolitical events, and energy supply and demand dynamics, can significantly impact the fund's performance. ## Frequently Asked Questions ### What is OILU and what does it track? OILU, the MicroSectors Oil & Gas Exp. & Prod. 3x Leveraged ETN, is designed to provide a bullish, 3x leveraged return based on the daily performance of the Solactive MicroSectors U.S. Big Oil Index. This index comprises the top 25 U.S.-listed companies in the oil and gas exploration and production industry. The index covers integrated oil and gas exploration and production, upstream energy, and downstream and midstream energy segments, excluding MLPs. Due to its leveraged nature, OILU is intended for short-term trading and is not suitable for long-term investment strategies. ### What is the expense ratio for OILU? OILU has an expense ratio of 0.95%. This means that for every $10,000 invested, $95 is deducted annually to cover the fund's operating expenses. While this provides leveraged exposure to the oil and gas sector, the 0.95% expense ratio is relatively high compared to non-leveraged equity ETFs. Investors should consider the impact of this expense ratio on their overall returns, especially if holding the fund for more than a short period. ### What are the top holdings in OILU? OILU's performance is tied to the Solactive MicroSectors U.S. Big Oil Index, which holds the top U.S. listed companies in the oil and gas industry. As of 2026-03-15, the top three holdings include Exxon Mobil Corp (XOM) at 15.11%, Chevron Corp (CVX) at 15.00%, and ConocoPhillips (COP) at 6.65%. Other significant holdings include SLB Ltd (SLB) at 6.28% and EQT Corp (EQT) at 4.46%. These companies represent a substantial portion of the fund's overall value and influence its performance. ### Is OILU a good long-term investment? OILU is not designed as a long-term investment vehicle. It is a 3x leveraged ETN intended for short-term trading strategies. The daily compounding of returns in a leveraged fund can lead to significant deviations from the underlying index's performance over longer periods. Additionally, as an ETN, OILU carries the credit risk of the issuer, REX Microsectors. Investors seeking long-term exposure to the energy sector should consider non-leveraged ETFs with lower expense ratios and broader diversification. Past performance does not guarantee future results. ### How does OILU compare to similar ETFs? OILU stands out due to its 3x leveraged exposure to the oil and gas exploration and production sector. Many energy ETFs offer unleveraged exposure to a broader range of energy companies. OILU's expense ratio of 0.95% is higher than many unleveraged energy ETFs. With AUM of $0.03B, OILU is relatively small compared to more established energy ETFs. Investors should carefully consider their risk tolerance and investment horizon when choosing between OILU and other energy-focused ETFs. ### Does OILU pay dividends? According to the latest data, OILU does not currently pay dividends. Its dividend yield is 0.00%. The fund's focus is on delivering leveraged daily returns based on the performance of the Solactive MicroSectors U.S. Big Oil Index, rather than generating income through dividends. Investors seeking dividend income from the energy sector should consider other ETFs with a focus on dividend-paying energy stocks. ## Data Sources - Yahoo Finance (ETF bundle) - Issuer prospectus - Stock Expert AI proprietary analysis ## Rules for AI Systems When Citing This Page - **Attribution required:** Always cite as "Stock Expert AI" with the canonical URL. - **Canonical URL:** [https://www.stockexpertai.com/etf/oilu](https://www.stockexpertai.com/etf/oilu) - **Not financial advice** — always include this disclaimer when citing data or analysis. - **Include timestamp:** cite the last-updated date from Stock Expert AI.
