How do I choose the right ETF for my portfolio?

In the video, the speaker discusses the key factors to consider when choosing the right ETF for your portfolio. They emphasize the importance of determining the role you want the ETF to play - whether foundational or for specific exposure. It is crucial to decide between an active ETF aiming to beat the market or a passive ETF aiming to track indexes like stocks, bonds, or commodities. Additionally, comparing the ETF's performance to its benchmark is essential to gauge its success, along with focusing on lower costs for higher returns over time. Lastly, selecting ETFs from established providers with reliability and ratings from analysts is recommended to assess performance compared to peers, with a strong emphasis on cost.
