FXN vs RSPG

Key Takeaways

• Different construction philosophies: FXN uses a multi-factor AlphaDEX methodology with a mid-cap tilt, while RSPG applies pure equal weighting to the largest U.S. energy companies.
• Cost gap: RSPG carries a 0.40% expense ratio versus roughly 0.63% for FXN, giving RSPG a structural cost advantage.
• Holdings breadth: FXN holds roughly 40 to 42 names, while RSPG holds only about 22 to 24 large-cap energy stocks, making RSPG more concentrated at the mega-cap end.
• Exposure profile: FXN leans toward exploration and production (E&P) and natural-gas producers, whereas RSPG distributes weight more evenly across integrated majors, refiners, and oilfield services.
• Rebalancing and strategy: Both are passively managed, but RSPG rebalances quarterly and FXN is a rules-based, tiered equal-weighted index built to capture excess returns (alpha) relative to traditional benchmarks.

Introduction

Energy has re-emerged as one of the most closely watched corners of the U.S. equity market, driven by commodity price swings, capital discipline among producers, and shifting global supply dynamics. Investors seeking sector exposure often confront a key question: should they own a broad equal-weight basket of energy giants or a factor-driven portfolio that tilts toward smaller, higher-momentum names? This ETF comparison examines the First Trust Energy AlphaDEX Fund (FXN) against the Invesco S&P 500 Equal Weight Energy ETF (RSPG), two funds that compete for the same investor dollar yet pursue meaningfully different construction methods and risk profiles.

First Trust Energy AlphaDEX Fund (FXN) Overview

The First Trust Energy AlphaDEX Fund seeks to track the StrataQuant Energy AlphaDEX Index, a rules-based benchmark that selects and ranks large- and mid-cap U.S. energy stocks from the Russell 1000 Index using a blend of growth and value factors combined with relative strength. The result is a modified, tiered equal-dollar-weighted portfolio rather than a straight market-cap weighting. FXN typically holds about 40 to 42 positions, with a top-10 concentration near 44% of assets.

Its recent top holdings have included DINO (HF Sinclair), APA, DVN (Devon Energy), RRC (Range Resources), AR (Antero Resources), EQT, and COP (ConocoPhillips). Energy represents roughly 96% of the portfolio, with a pronounced weighting toward independent E&P and natural-gas names. The fund charges a net expense ratio of approximately 0.63% and has been available since May 2007, positioning it as a factor-tilted, more mid-cap-oriented vehicle within the energy universe.

Invesco S&P 500 Equal Weight Energy ETF (RSPG) Overview

The Invesco S&P 500 Equal Weight Energy ETF seeks to track the S&P 500 Equal Weight Energy Plus Index, which equally weights the energy constituents of the S&P 500 as classified under the Global Industry Classification Standard (GICS), the sector taxonomy used by S&P and MSCI. The index holds a minimum of 22 names and is rebalanced quarterly. RSPG generally holds about 22 to 24 positions and employs full replication of the index.

Because every holding is reset to an equal weight each quarter, no single mega-cap dominates. Recent top holdings have included MPC (Marathon Petroleum), VLO (Valero Energy), PSX (Phillips 66), XOM (ExxonMobil), KMI (Kinder Morgan), and CVX (Chevron). The fund is essentially 100% allocated to energy, spans integrated oil majors, refiners, and oilfield services, and carries a lower net expense ratio of 0.40%. Launched in November 2006, it is among the more established equal-weight sector products.

Industry and Thematic Backdrop

Both funds sit squarely within the energy sector, but their behavior is shaped by distinct segments of the value chain. Global oil supply discipline, natural-gas demand tied to electrification and data centers, and capital-allocation priorities among producers have all influenced sector flows in recent market cycles. Refiners and integrated majors tend to be more sensitive to crack spreads and downstream margins, while independent E&P and gas producers are more directly levered to commodity prices and drilling economics.

Interest-rate expectations and the U.S. dollar also matter, as energy equities have historically displayed meaningful sensitivity to macro shifts. Regulatory and geopolitical developments, including export policies and supply disruptions, remain recurring catalysts. For a sector known for cyclicality, the principal risk shared by both funds is a sharp, sustained pullback in oil or natural-gas prices.

Performance and Positioning Comparison

In recent weeks and across recent market cycles, the two funds have generally tracked the broader energy complex but with notable divergence in relative positioning. FXN, with its heavier mid-cap and gas-producer exposure, has tended to amplify moves in commodity prices and in higher-beta E&P names, contributing to somewhat elevated volatility. RSPG, by contrast, has offered a steadier, large-cap-dominated profile because its equal-weight structure smooths out single-stock risk across integrated majors, refiners, and diversified energy companies.

From a structural standpoint, RSPG's lower expense ratio and broader subsector diversification provide a more cost-efficient core allocation, while FXN's factor-driven tilt can deliver differentiated returns when smaller, value-oriented energy names outperform. Relative positioning therefore comes down to whether an investor favors disciplined broad diversification or a more dynamic, mid-cap-leaning factor exposure.

Tickeron AI Verdict

Based on observable structural characteristics, Tickeron's AI would likely lean toward RSPG in the current environment. Its materially lower expense ratio, broad subsector diversification across integrated majors, refiners, and oilfield services, and more predictable quarterly rebalancing provide a steadier, lower-cost core within a volatile sector. While FXN offers greater potential upside through its mid-cap and natural-gas tilt, that same tilt introduces higher concentration and volatility risk. The AI's preference reflects a probabilistic assessment favoring cost efficiency and diversification, rather than any certainty about near-term commodity prices.
