Index fund investing has transformed UK personal finance over the last decade. The combination of low-cost platforms, the ISA tax wrapper, and decades of evidence showing passive beats active makes this the default recommendation for most UK investors.
Key UK index funds and ETFs
| Fund/ETF | Index tracked | OCF | Platform |
|---|---|---|---|
| Vanguard FTSE All-World ETF (VWRL) | ~3,700 global stocks | 0.22% | Most platforms |

FTSE All-World vs S&P 500 vs FTSE 100
- FTSE All-World (VWRL, FWRG): Most diversified — ~3,700 companies across 49 countries. The default recommendation for UK investors who want global diversification without home bias.
- S&P 500 (CSP1, VUAG): 500 largest US companies. Higher historical returns than FTSE All-World but more concentration in US equities. ~65% of FTSE All-World is US anyway.
- FTSE 100: UK's 100 largest companies. Historically underperformed global indices. Heavy in financials, energy, and mining. Avoid as your only holding.
