I have no problems with single country trusts. I am “risk on” for the next 4 years possible longer. I have £314 state and disability pension the latter isnt taxable. It’s more than adequate amount for me to live on.
So I see no problems with taking risks.
In fact in the present market I think you would be foolish not to.
The extreme volatility is throwing up bargains constantly.
Private equity is still in the bargain basement.
