Key Takeaways
- • A five-ETF screening strategy is outperforming its benchmark, demonstrating that diversified ETF portfolios can deliver superior risk-adjusted returns compared to single-index approaches.
- • Sector and momentum-focused ETFs, including funds tracking developed international markets like the iShares MSCI EAFE ETF (EFA), have significantly outpaced large-cap U.S. equity benchmarks—EFA returned 31.5% in 2025 versus 17.8% for the S&P 500.
- • Positive screening strategies (inclusion-based ESG criteria) in passively managed ETFs have demonstrated the ability to beat market benchmarks with statistically significant abnormal returns, particularly through environmental inclusion screens.
- • Successful ETF portfolio construction prioritizes performing across market cycles rather than chasing recent winners; sector and momentum funds are best deployed as satellite positions rather than core holdings.
- • Over 80% of smart beta index portfolios have beaten their respective benchmarks since inception, suggesting that factor-based and rules-driven ETF strategies offer a viable alternative to traditional cap-weighted indexing.
Summary
The investment community has long debated whether beating the S&P 500 should serve as the primary success metric for portfolio performance. A five-ETF screening strategy highlighted by Investors' Chronicle demonstrates that when properly constructed around complementary asset classes and strategic factors, diversified ETF portfolios can consistently outperform broad market benchmarks. The key insight is that the S&P 500 represents only one asset class—large-cap U.S. equities—and different asset categories deliver superior returns at different points in the market cycle.
International developed markets provided a compelling example of this rotation in 2025. The iShares MSCI EAFE ETF (EFA), which tracks large- and mid-cap equities outside the U.S. and Canada, returned 31.5% for the year, substantially outpacing the 17.8% return of the iShares Core S&P 500 ETF (IVV). This performance differential underscores a critical portfolio management principle: successful asset allocation depends on positioning across multiple cycles rather than concentrating capital in a single dominant asset class during periods when it underperforms.
Research on passive ESG and factor-based ETF strategies provides additional evidence for the outperformance thesis. Academic analysis shows that positive screening methodologies—particularly environmental inclusion screens—deliver significantly higher abnormal returns compared to negative screening approaches. Smart beta index portfolios, which use factor-based construction rules rather than market-cap weighting, have exceeded their respective benchmarks more than 80% of the time since inception, validating the efficacy of rules-driven diversification strategies.
The practical application of a multi-ETF screen requires disciplined portfolio construction. Sector and momentum-focused ETFs are most effective as satellite positions complementing a core holding rather than replacing it entirely. Investors evaluating any ETF strategy must ensure the fund's methodology aligns with broader portfolio objectives and risk tolerance, recognizing that performance leadership shifts across market cycles. The VanEck Social Sentiment ETF, for example, delivered 20.15% returns in May 2025, demonstrating how specialized, thematically focused ETFs can capture outsized gains during favorable sentiment windows. Ultimately, the five-ETF screening approach succeeds not by consistently beating the S&P 500, but by delivering diversified exposure that performs resiliently across varying economic and market conditions.
