VOO vs RSP ETF Comparison: AI Score, Valuation, Performance and Upside
VOO and RSP hold the same companies and differ only in weighting, which turns out to matter a great deal. VOO's cap weighting concentrates assets in the largest companies and performs best when they lead. RSP weights members roughly equally and rebalances, giving a mid-cap tilt, better single-stock diversification, and weaker results when mega caps dominate.
Use this VOO vs RSP comparison as a view on market breadth. If you expect returns to keep coming from a small number of very large companies, cap weighting captures that automatically. If you expect leadership to broaden, equal weighting participates more fully, at the cost of higher turnover and expense.
VOO holds the edge across 3 of 5 key metrics in this comparison. VOO has delivered stronger 1-year price return (+18.56% vs +14.87% for RSP).
- Want the standard cap-weighted benchmark at minimal cost

- Value very low turnover for tax efficiency
- Prefer no mechanism that trims winners
- Want to reduce single-stock concentration within the S&P 500
- Expect market leadership to broaden beyond the largest names
- Value systematic rebalancing that trims winners and adds to laggards
- Accept higher turnover, higher cost, and underperformance during narrow rallies

The ETF score weights long-term returns and risk-adjusted performance most heavily, but still rewards low expense ratios, larger fund size, and broader diversification — so it can favor low-cost, broad, mega-cap funds over smaller thematic or actively-managed funds even when the latter have delivered stronger returns.

- Cap weighting lets winners run, which has historically favoured holding the market's leaders
- Very low cost and minimal turnover, which is tax-efficient in taxable accounts
- The standard benchmark against which most US equity performance is measured
- Removes single-stock concentration risk from the largest holdings
- Rebalancing systematically trims what has risen and adds to what has lagged
- More balanced sector exposure than a cap-weighted index at times of narrow leadership
- Concentration in a handful of very large companies has risen substantially
- Sector weights drift toward whatever has performed best, reducing diversification at peaks
- Offers no mechanism to trim positions that have become expensive
- Lags badly during periods when very large companies drive index returns
- Regular rebalancing creates higher turnover, with cost and tax consequences
- Costs more to own than the largest cap-weighted index funds
