Start investing with core ETFs
Why include core ETFs in your investment portfolio?
Core ETFs are often used as the foundation of a long-term investment portfolio. They offer a simple and cost-efficient way to invest in markets through a single trade. By tracking broad market indices, core ETFs provide instant diversification across countries, sectors, companies or bonds. This helps spread risk and can reduce the impact of individual market movements on your portfolio.
Core ETFs can form the foundation of a portfolio and be combined with other investments to reflect different investment goals, time horizons and risk tolerances.
Diversification does not fully protect against market risks.
Capital at risk. The value of investments and the income from them can fall as well as rise and are not guaranteed. Investors may not get back the amount originally invested.
