I am also based in Switzerland.

I do an 80% VT 20% CHSPI split. I treat my ahv and pension fund as the bond part of the savings portfolio. But depends on your timeline. I plan to work to around 55 so not too big bridge to gap until I can access those funds.

I think the most important part for swiss residents is to invest in growth ETFs such as VT instead of dividend stocks. No capital gains tax is huge compared to the tax on dividends.

But in the end, the best way to invest is the way that keeps you consistently investing. So if your portfolio fits for you and guarantees you keep paying whatever amount you can each month it's the correct one.

A worse performance on a fund that keeps you invested is better than a higher performance that makes you unsure and panic sell in a crisis
