I understand your fears, and have no objections to people owning a small amount of gold. But what worries me is your use of the word “distribution.” Are you planning to take the money OUT of a retirement plan? Don’t do that! It would be subject to taxes.
Instead, buy the ETF called GLD — it represents the price of gold bullion on an instant basis. If there is a brokerage option inside your retirement plan (if it’s a 40l(k))then you should use that tactic. If you have an IRA, then just buy that stock. It moves exactly with the price of gold — a small “insurance policy.”
