Hi,
You could open a portfolio with Viac (100% Global or something), and then spread out the 526/yr to 10 CHF per week.
That’ll provide some benefits from continuous rebalancing, volatility pumping, and more generally, the buy-low-sell-high effect if done for long enough.
See my experiments in this thread:
NB: The maximum you’ve quoted above was from 2019/2020. It has since been raised to 7’056 CHF.
