2 Vanguard Index Funds to Beat the S&P 500 Over the Next 10 Years, According to Analysts

Vanguard's Capital Markets Model forecasts annualized returns of 6.8% for value stocks and 6.2% for small-cap stocks over the next decade versus 4.9% for U.S. equities and 4.8% for large caps. Valuation spreads are wide: Russell 1000 Growth trailing P/E 39.32 vs Russell 1000 Value 22.12, and S&P 500 forward P/E 24 vs S&P 600 at 16. Vanguard recommends low-cost ETFs to gain exposure—Vanguard Value ETF (VTV) and Vanguard Small-Cap ETF (VB), each with a 0.03% expense ratio—and notes YTD 2026 returns of +4% (VTV) and +3% (VB) vs S&P 500 -1%. Portfolio tilt toward value and small-cap is suggested for potential long-term outperformance, while acknowledging valuations are poor short-term return predictors.

Analysis

The current valuation wedge between large-cap growth and small-cap/value implies a low-risk arithmetic edge for the latter: a 1.3–2.0% higher annualized return expectation translates to roughly a 22%–25% cumulative relative outperformance over a 10-year horizon if realized. That kind of multi-year delta is most potent when combined with active rebalancing and pair trades because it compounds against a concentrated growth cohort whose weight is already regime-dependent.

Secondary market mechanics matter: a rotation into small-cap/value will tighten liquidity in those names, compressing short-term volatility but also increasing takeover and activist-arbitrage activity (M&A tends to accelerate when smaller caps re-rate), which compresses realized returns dispersion and benefits concentrated active managers. Conversely, small caps’ balance-sheet and credit sensitivity mean a credit spread widening or a domestic slow-down could erase the valuation premium quickly — so timing and hedging matter.

Key catalysts to watch in the next 3–12 months are (a) sector-level earnings revisions (financials/industrials beating would validate value), (b) credit spreads/Russell 2000 liquidity metrics, and (c) continued concentration or dispersion of AI-driven cashflows (NVDA/INTC/NFLX dynamics). The largest single reversal risk is persistent growth outperformance driven by secular profits from AI/network effects; if that continues beyond 12 months, expect multi-quarter delays to the reversion trade.

Key Decisions for Investors

• Pair trade (6–24 months): Long VTV 3% portfolio weight vs short QQQ 3% (notional matched). Target 200–350 bps annualized relative gain; initial stop if VTV underperforms QQQ by 6% within 3 months. Rationale: capture value re-rate while hedging market-beta and tech concentration risk.
• Small-cap convexity (9–18 months): Buy VB outright on any 3–5% pullback from current levels or implement buy Jan-2028 LEAPS call spread (long 1 LEAP call, short a nearer-term OTM call to finance ~50% premium). Size to 2–4% portfolio. Risk/Reward: asymmetric upside if small-cap re-rating occurs; limited financed downside via call-sell leg.
• Defensive hedge (0–12 months): Buy QQQ 3–6 month puts (or a short Nasdaq futures position) sized to offset worst-case drawdown from a tech-led reversal. Cost should be treated as insurance — acceptable if <25–30 bps annualized drag for portfolio protection.
• Tactical monitoring & triggers: Add to small-cap/value builds if (a) Russell 2000 forward P/E falls to <75% of S&P 500 forward P/E gap or (b) credit spreads tighten by >30bps YTD. Trim or flatten positions if mega-cap earnings surprise positively and QQQ outperformance persists >12 months.
