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

Vanguard's Capital Markets Model projects 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-cap. Valuation spreads are wide (Russell 1000 Growth trailing P/E 39.32 vs Russell 1000 Value 22.12; S&P 500 forward P/E 24 vs S&P 600 16), supporting the expected premium. Vanguard highlights two low-cost ETFs — VTV and VB (each 0.03% expense ratio) — and notes YTD 2026 performance of VTV +4% and VB +3% vs S&P 500 -1%; consider a modest tilt to value/small-cap as a long-horizon diversification move, recognizing valuations are a long-term signal rather than a short-term timing tool.

Analysis

Valuation dispersion is a liquidity and positioning story as much as a fundamental one. When passive and factor flows rotate toward underowned segments, the first-order effect is price appreciation; second-order effects show up in microstructure — rising borrow costs and widening options skews for formerly cheap names, and temporary compression of bid depth in small caps that can amplify short-term volatility even as realized returns drift higher over years. Expect pockets of illiquidity to create short-term drawdowns that can look like failed rotations unless investors account for execution and holding-cost friction.

Winners extend beyond the obvious ETFs: regional banks, specialty lenders, and B2B SMB vendors that feed small-cap working capital needs will see measurable margin expansion if a durable rerating materializes — loan yield compression or credit tightening would reverse that quickly. Conversely, incumbents that derive valuation premia from optionality (AI leaders and platform monopolists) could lose index-weighted share without immediate earnings deterioration; their suppliers (high-end semicap equipment, hyperscale datacenter integrators) face lumpy demand signals rather than steady declines.

Timing and catalysts are hierarchical: the trade is multi-year (3–7 years) to capture mean reversion in multiples, but it will be punctuated by near-term catalysts — CPI/Fed guidance, small-cap earnings surprises, and passive rebalancing windows. Tail risks include a persistent dispersion premium driven by structural concentration (passive flows, indexation) or a credit shock that disproportionately hits smaller companies; both can keep the spread intact or invert it unexpectedly within 1–12 months.

The consensus underestimates the cost of being early. A phased, hedged implementation captures most of the long-term edge while limiting the pain of interim reversals. Conversely, the market can also remain “wrong” for years; treat any active exposure as carry-plus-convexity rather than a timing bet — size slowly, hedge tails, and watch borrowing/liquidity metrics as your real-time risk gauges.

Key Decisions for Investors

• Relative-value pair: Go long VTV (or another large-cap value ETF) and short QQQ to neutralize beta. Size: 3–5% net equity tilt (long leg) with short leg sized to target 0.0–0.2 net market beta. Timeframe: 12–36 months. Risk/reward: expects 200–400bp annualized excess over funds over 3 years; stop-loss: close pair if QQQ/VTV 90-day z-score > +2.0 or if S&P futures gap down 6%+ on systemic event.
• Small-cap pro-cyclical outright with tail hedge: Buy VB-sized exposure via dollar-cost averaging over 6 months totaling 2–4% portfolio weight, and purchase 6–12 month puts on IWM or a 1.5% portfolio allocation to a short-dated VIX call spread as crash insurance. Timeframe: 24–48 months to realize multiple expansion. Risk: credit tightening or recession would cause meaningful drawdown; reward: capture multi-year rerating.
• Pair trade expressing AI durability risk: Short a concentrated growth basket (e.g., top-5 mega-cap futures/ETFs) and allocate proceeds to high-quality small-cap/value names and regional bank debt funds. Timeframe: 6–24 months around major macro prints (Fed/PCE). Risk/reward: if AI earnings sustain, this trade loses to a cap-weighted concentration; cap the loss at 6% of NAV per event by scaling exposure and using options collars.
• Event trigger option: Buy 9–12 month VTV LEAPS or long-dated calls on a diversified small-cap value ETF on a 1–2% notional basis to capture convex upside while limiting premium outlay. Add a contingent execution plan to add delta if CPI prints below 2.5% or the 2-year/10-year spread steepens by >50bps, which historically favors small-cap rerating.
