For the young investors, do you include bonds in your portfolio?

I think there are many strategies out there and it is really up to you whether you prefer this over that.

There's one strategy called the 110-Age = Stock allocation and there's also one that is called ray dalio all weather portfolio where he allocates 60% to bonds.

I think if you are younger, you should take on more risk thus having allocate more into stocks. I think a small amount of bonds and commodity is fine.

I do not hold any bonds bonds. If you think that your CPF is a bond sure.
