Index Funds

The single boring decision that determines most of your investing outcome over a thirty-year horizon.

Index funds are the highest-leverage decision a long-term investor makes. The data is unambiguous: over rolling twenty-year windows, the global market beats roughly 90% of active funds, and the gap is roughly equal to the fee difference. A 0.13% global tracker against a 0.75% active fund over thirty years is a thirteen-percent compounded haircut you didn't need to take.

These articles cover the UK trackers worth holding. Your First Portfolio UK is the start-here piece - one global fund, regular contributions, no tinkering. How to Read an ETF Factsheet covers what to look for before you buy. The Bogleheads piece explains the philosophy behind the approach for readers who want the underlying intellectual framework before committing capital.
