Is it more sustainable to invest one’s finances into bonds as opposed to stocks? Which one generates higher long term ROI?

The theory says higher risk = higher potential return.

Wisdom also tells: Diversify! stocks, as well as bonds.

In the U.S. often there were traditional standard allocations

70/30 or 60/40% allocations stocks/bonds.

The theory says: stocks are risky but for Your (longterm) capital appreciation

& bonds are for stability into the portfolio. This even worked during the Covid crisis.

There are however warning voices: particularly corporate bonds could be defaulting en masse in the future because of all the debt.

I never owned bonds. The bond CAGR is generally very low currently with reliable higher quality bond allocation, with (in the distant future) rising interest rates, there could then be tears.
