Avanza Zero index change: What investors need to know

Avanza Zero, one of Sweden's most widely held index funds, is undergoing a major portfolio reshuffle as it prepares to switch its benchmark index. As of November 3, 2026, the fund is scheduled to transition from the current SIX30 Return Index to the new SIX30RXC index on November 16, 2026.

Why it is trending now

The index change is attracting significant attention because it requires the fund to sell and buy shares worth billions of kronor to align with the new composition. Because the new index focuses on 30 individual companies rather than 30 share classes, the fund must adjust its holdings, which directly impacts the investment portfolios of its 1.1 million owners.

Key facts

• The transition to the SIX30RXC index is officially set for November 16, 2026, according to EFN.
• Market estimates indicate that the rebalancing could involve trading volumes of approximately 17 billion SEK, as reported by Börsvärlden.
• Companies including Getinge, Sinch, Electrolux, and likely SCA are expected to exit the fund, while firms such as Skanska, Sobi, and Industrivärden are projected to enter, based on data cited by EFN.
• The final composition of the index has not yet been confirmed by the index provider, SIX, meaning current projections remain speculative.

Why this is trending in Sweden

Avanza Zero is a staple for Swedish retail investors due to its fee-free structure and broad accessibility. The high volume of Swedish users searching for this term reflects concern regarding how the forced sale and purchase of shares will impact individual savings and fund performance.

Background and context

Avanza Zero has traditionally tracked the OMXS30-related index. The shift to SIX30RXC represents a technical adjustment in how the underlying 30 companies are selected, specifically incorporating adjustments for market capitalization and the proportion of shares available for public trading.

What happens next

The fund will finalize its holdings on November 16, 2026. Until the official index composition is published by SIX, the exact list of companies entering or exiting the fund remains unconfirmed. Investors are advised to monitor official communications from Avanza for updates on how their specific holdings may be affected by the transition.
