Gold’s price history shows a real, if inconsistent, tendency to move independently of (and sometimes opposite to) stocks during equity downturns — that’s the mechanism behind the volatility-reduction claim, and it has some historical support. It is not a guarantee: gold has also fallen alongside stocks in some sell-offs, including parts of 2008 and March 2020.

How Much Volatility Reduction Is Realistic

Modeling commonly cited by financial planners suggests a modest allocation (5-15% of a portfolio) in gold can measurably reduce overall portfolio swings without giving up much long-term return, because gold’s correlation to stocks, while variable, tends to run low over multi-year periods.

The Account-Level Requirements

Achieving this inside a tax-advantaged account means holding IRS-approved physical metal (99.5% purity minimum under 26 U.S.C. §408(m)(3)) through an approved custodian and depository — the volatility-reduction case is about the asset, but capturing it in an IRA requires the standard Gold IRA structure.
