Top 2 Index Funds to Beat the S&P 500 Over the Next 5 Years, According to Wall Street

S&P 600 returned to positive year‑over‑year earnings growth in Q2 2025 after 11 straight quarters of declines and is forecast to deliver higher earnings growth than the S&P 500 by late 2026. Small caps currently trade at a P/E more than ~30% below large caps, suggesting upside if earnings momentum persists; iShares Core S&P Small‑Cap ETF (IJR) offers exposure at a 0.06% expense ratio and Vanguard Mid‑Cap ETF (VO) at 0.03%, with VO ~20% in Industrials and 13–15% in consumer discretionary, financials and tech. This is a tactical, modestly bullish view favoring a rotation away from pricey AI megacaps toward small/mid caps; the piece is advisory commentary (Motley Fool discloses positions in both ETFs) and is unlikely to move markets broadly on its own.

Analysis

We are entering a regime where leadership can rotate away from concentration-driven megacaps toward more cyclically exposed SMID names — not because they suddenly become safer but because the market’s plumbing (ETF flows, benchmark reweights, and multi-manager allocations) will mechanically bid those securities as short-term earnings momentum and relative valuation gaps become apparent. Expect the clearest second-order beneficiaries to be providers to domestic capex and services (machine tool OEMs, industrial distributors, regional payments rails) whose revenue sensitivity to U.S. end-demand is higher than megacap revenue tied to global hyperscaler budgets.

Credit and liquidity are the underappreciated transmission channels: improving operating income at SMID firms should reduce near-term default risk and tighten spreads in the lower-investment-grade market, which in turn will draw more discretionary yield-chasing capital into SMID equities via closed-end funds and multi-strategy overlays. Conversely, the same dynamic can create crowding: limited free float and thinner options/implied vol markets in small caps mean a relatively modest flow can spike realized vol and produce painful downside for levered holders.

Tail risks that would reverse this trade are classic — a renewed inflationary shock, a sharp dollar rally, or another wave of supply-chain/tariff shocks that disproportionately raise input costs for domestically-focused producers. Time horizon matters: tactical relative outperformance can happen in 3–9 months off a positive earnings surprise cycle, while a durable re-rating requires 12–36 months of stable margin expansion and a benign rates backdrop. The consensus is underestimating execution risks in earnings recovery for SMID: revenue beats won’t stick without margin recovery and working-capital normalization, so position sizing and dynamic hedges are essential.

Key Decisions for Investors

• Pair trade — Long IJR / Short SPY, equal-dollar basis, 9–18 month horizon. Target relative outperformance +12–18% (gross) if SMID margins re-rate; initial sizing 3–5% NAV with a 6% relative stop. Rationale: capture re-rating and flow-driven bid while limiting market beta.
• Mid-cap income-overlay — Buy VO (3% NAV) and sell 6-month near-the-money covered calls to finance cost. Expect to generate ~6–10% annualized carry while participating in upside; roll or unwind if calls are exercised or if VO outperforms by >15% in 3 months to avoid forced liquidity.
• Convex tail hedge — Buy 3–6 month NVDA (or QQQ) put spread to cap tech-drawdown tail risk; allocate 0.5–1.0% NAV. This hedge protects the pair trade from a rapid tech-led market shock that would flip the rotation and generate negative gamma for SMID positions.
• Credit-sensitive long — Overweight a basket of regional banks and industrials (select names or KRE-sized exposure) for 12–24 months to capture tightening in lower-grade credit and higher SME lending activity. Target absolute return 15–25% if default rates normalize; use 8–10% stop if macro credit indicators (HY OAS, loan delinquency rates) deteriorate materially.
