What is an index fund?
An index fund is an investment fund that aims to track the performance of a specific index. An index is a collection of securities representing a market or part of a market. For example, a global index fund might aim to track broad stock markets worldwide. In practice, this means the fund buys the same securities in roughly the same proportions as the index.
Index funds are often described as passively managed. This means the fund’s management does not try to beat the market by selecting winners, but instead mirrors the index. This contrasts with actively managed funds where managers try to outperform the index through stock selection.
Common terms you may encounter
- Index: A list of securities representing a market or a portion of it.
- Fund: A pool of securities owned by fund shareholders.
- Management fee: The annual charge for operating the fund.
- Total Expense Ratio (TER): The total annual costs of running the fund expressed as a percentage of assets.
- Tracking error: How much the fund’s return deviates from the tracked index.
Why choose index funds?
- Costs: Index funds often have lower fees than actively managed funds because they follow a fixed rule set rather than trying to pick winners.
- Diversification: By investing in a broad range of securities, the fund spreads risk.
- Transparency: You know what the fund aims to track and what’s in the index.
- Simplicity: For those who don’t want to spend time selecting individual stocks, index funds can offer a straightforward option.
Important considerations before you start
- Risk: All stock market investments involve the risk of loss. Prices can swing significantly in the short term.
- No guarantees on returns: Past performance does not guarantee future results, and index funds will experience downturns when markets fall.
- Costs affect returns: Higher fees can erode long-term returns.
How index funds work in practice
Index funds invest in the securities that make up their chosen index in roughly the same proportions, enabling a close approximation of the index’s performance. There is usually some tracking error due to costs, liquidity, and other practical factors. Returns thus closely reflect the index’s performance after expenses.
What to watch for when choosing an index fund
- Market coverage: Prefer funds that track broad indices for better diversification.
- Costs: Look at annual fund fees and any purchase/sale costs.
- Index specifics: Some funds track global markets, others focus on regions or sectors. Choose according to your goals and horizon.
- Fund size and liquidity: Larger, more liquid funds tend to have smaller bid-ask spreads when trading.
- Implementation aspects: Ensure the fund fits with your account type and whether automated regular purchases are available.
How to get started in Norway – a simple step-by-step plan
- Clarify goals and horizon
- Define why you are saving and how long you plan to keep the investment. A longer horizon usually allows more time to endure volatility.
- Consider how much you can commit now and monthly without compromising financial safety.
- Choose fund type and index
- Decide whether you want global exposure or a regional focus. Global indices often provide broader diversification.
- Consider how many funds you want; many start with one broad global index fund and optionally add a region or theme.
- Check costs and terms
- Look at annual costs and any purchase/redemption fees.
- Ensure the fund trades in your preferred currency and understand how currency exposure is handled.
- Select the right account and platform
- Review which account type aligns with your tax situation and investment goals (for example, account types that enable simple saving and potential tax efficiency).
- Open an account and complete the required verification procedures.
- Set up and execute the purchase
- Use your bank or broker to search for the fund and place the purchase.
- Consider setting up automatic monthly purchases (dollar-cost averaging) to smooth out timing risk.
- Regular monitoring and simple rebalancing
- Schedule periodic reviews to ensure your allocation still matches your goals.
- Rebalancing adjusts holdings to your desired distribution, particularly after periods of strong performance in one part of the portfolio.
- Think long-term and keep it simple
- Index funds are often a straightforward way to achieve broad diversification, but they are not risk-free.
- Be mindful of risk and ensure investing fits your personal situation and timeline.
