Gold and Stock Market Volatility
Over long periods, gold's price has shown little consistent relationship with U.S. stock prices, which is why some people hold it as a potential diversifier when markets turn volatile. That low correlation is an average, though, not a promise: during the sharpest weeks of past selloffs gold has sometimes fallen alongside stocks before recovering, and its own price can swing widely.
The Problem: Volatility in a Concentrated Portfolio
Stock prices can drop quickly and by large amounts. On October 19, 1987, the Dow Jones Industrial Average fell about 22.6% in a single day, and broad U.S. stock indexes lost roughly half their value from peak to trough during the 2007–2009 bear market. Someone who needs to draw on savings during a decline like that may be forced to sell at low prices. Spreading holdings across assets that respond to different forces is one common way people try to reduce that risk, and precious metals can be one part of that mix.
Correlation in Plain Terms
Correlation measures how closely two prices move together, on a scale from −1 to +1:
- +1 means they move in lockstep.
- 0 means there is no consistent linear relationship.
- −1 means they move in exactly opposite directions.
For diversification, an asset does not need a negative correlation to be useful. A correlation near zero means its ups and downs are largely independent, which can smooth the overall ride of a portfolio. Correlations also change over time, so analysts often look at "rolling" correlations measured over, say, one or three years at a time.
What the Historical Data Show
Research published by the World Gold Council on its Goldhub site has found that gold's correlation with U.S. stocks has been low over multi-decade periods. Gold's demand comes from jewelry buyers, central banks, technology users, and people buying bars and coins, which are different drivers from the corporate earnings that move stocks.
A second pattern that some research highlights is that gold's correlation with stocks has tended to turn more negative during some significant equity declines, which is the moment diversification matters most. That tendency has not held in every episode.
When Gold Fell With Stocks
Two well-known periods show the limits:
- Autumn 2008. As the financial crisis peaked, gold dropped significantly for several weeks while stocks were falling. Gold then recovered and finished the crisis period higher.
- March 2020. In the first weeks of the pandemic, nearly every asset was sold for cash. Gold dipped before rising to new highs later that year.
A common explanation is liquidity: gold trades easily, so when holders face margin calls or need cash fast, it can be among the first things sold. Our page on how gold has behaved during recessions covers these episodes in context.
Measuring Market Fear
Many people track stock market volatility through the Cboe Volatility Index (VIX), which reflects options traders' expectations for S&P 500 swings over the next 30 days. FRED publishes daily VIX values alongside other market data. Comparing VIX spikes with gold's price can illustrate how the metal has responded during stressed periods, though no simple rule links the two.
Gold Has Its Own Volatility
A low correlation with stocks does not make gold stable. Gold fell for much of the 1980s and 1990s and dropped sharply in 2013. Silver, platinum, and palladium have often been more volatile still. Our comparison of gold vs stocks looks at both assets' long-run behavior, including periods when gold lagged.
How People Use This Idea
The diversification case for gold rests on owning it before volatility arrives, not on predicting when a selloff might happen. Approaches people describe include:
- Holding a fixed share of a portfolio in metals and rebalancing periodically, discussed in how much of a portfolio might go to precious metals.
- Buying gradually over time rather than all at once, described in buying gold on a regular schedule.
- Choosing a holding format that suits their needs, whether physical metal or a fund; see physical gold in an IRA vs a gold ETF.
Be cautious of sales pitches that lean on fear of a market decline. Pressure to buy quickly is a red flag, whoever the seller is, and the CFTC's Learn and Protect pages describe tactics used in precious metals fraud.

Frequently Asked Questions
Is gold negatively correlated with stocks?
Over long periods, the correlation has generally been close to zero rather than strongly negative. It has sometimes turned negative during stock declines, but not consistently.
Why does gold sometimes fall when stocks fall?
During acute stress, people and institutions may sell easily traded assets, including gold, to raise cash. In 2008 and 2020 this selling was followed by recovery.
Can precious metals reduce portfolio swings?
An asset with low correlation to the rest of a portfolio may reduce overall volatility, but it can also lose value on its own. Diversification does not prevent losses.
Where can I see historical correlation data?
The World Gold Council's Goldhub publishes correlation and performance tools, and FRED provides free data for stock indexes and volatility measures.
