Index fund (indexfond)

Figures for tax year 2026Updated July 2026
Definition

An indexfond (index fund) simply tracks a market index, for example a broad global index, instead of a manager picking individual stocks. Because there is little to manage, the fee is low, and you own a slice of the whole market in one holding.

Passive vs active

An actively managed fund tries to beat the market by choosing what to hold, and charges more for the effort. The catch is that after fees, most active funds do not beat a comparable index over ten years or more. A cheap index fund quietly captures the market return, and the low fee is a head start that compounds.

Broad is the point

The usual core is a broad global index fund: thousands of companies across many countries in one holding, which spreads risk far better than a handful of Swedish names. It is why “a low-cost global index fund” is the default recommendation for long-term saving.

Compare within a category

Two global index funds tracking the same index will perform almost identically before fees, so the deciding factor is the TER. Pick the cheapest broad fund that fits your risk, not the one with the best recent chart.
