I thought about how to balance my portfolio between low-risk and high-risk investments and at the same time between IRA, IRA Roth, and normal investment accounts.
(This question is not about how to get money into or out of IRA and IRA Roth - assume it's already there and shall stay there)
Considering that high-risk investments are expected to bring the higher yield, it seems to be a good idea to have those in the IRA Roth (where the gains are tax-free), and cover the lower-risk/low-yield investments in the normal account (where the gains are taxable).
This seems to be a useful approach, independent of the personal risk-adversity - sort your desired investment types by risk/yield expectations, and make the highest ones inside the Roth, and the remainder in the normal account.
Am I missing anything here, or is this correct?
