I don’t get it. Investing in equities is a protection against inflation. Why would you want a safe ETF. With reduced returns? The returns are the offset of inflation.
Invest for long term. If you want a short term haven against inflation, then you are over thinking it. Because what is short term? 6 months? 12? How much is your fear?
If you think you will need quick access to your investment, then Gold. But don’t reduce the upside potential in individual equites during a peak in inflation. Sales revenue increases and profit increases. As the metrics of year over year sales are measured in dollars.
