Gold (GC=F) futures opened at $3,986.90 per ounce on Friday, nearly the same as Thursday’s close of $3,991. The price of gold rose above $4,000 in early trading.

Gold’s small boost Friday morning follows a down week for stock prices. The three major indexes, S&P 500 (GSPC), Dow Jones Industrial Average (DJI), and the Nasdaq Composite (IXIC), have produced losses this week. The tech-heavy Nasdaq has performed the worst of the three and is down 3.7% since Monday’s open.

Concerns about high valuations on AI stocks is a factor. Investor Michael Burry of Scion Asset Management disclosed Monday that his fund bet that two leading AI stocks, Nvidia (NVDA) and Palantir (PLTR), would lose value. Burry is known for predicting the collapse of the U.S. housing market in 2008.

An uncertain outlook for stock prices often drives higher safe-haven demand for gold.

The opening price of gold futures on Friday was flat with Thursday’s close of $3,991. Here’s a look at how the opening gold price has changed versus last week, month, and year:

One week ago: -1.2%

One month ago: +0.7%

A gold investment can add stability and inflation protection to your portfolio. But it can also dilute your gains when stock prices are rising quickly. Finding the right balance between gold’s diversification benefits and profiting from growth potential in other assets can be challenging.

Even the experts are divided on how to achieve the correct balance. Below, five experts explain their recommended gold allocations, which range from 0% to 20%.

Robert R. Johnson, professor at Creighton University’s Heider College of Business, does not advocate gold investing. In his words, “while having a small position in precious metals may dampen portfolio volatility in the short-run, the tradeoff between slightly dampened volatility and the lost long-term return is certainly not a prudent one, particularly for Gen Z/millennials with long investing time horizons.”

Brett Elliott, director of content and SEO at American Precious Metals Exchange (APMEX), recommends setting an allocation that aligns with your investing goals.

Growth-oriented investors may be comfortable with an allocation of 10% or 15%, according to Elliott. But income investors will prefer a smaller position, because gold provides no yield. A 2% to 5% gold allocation can provide some resiliency without an excessive drag on income potential.

Blake McLaughlin, executive vice president at Axcap Ventures, said historical data support a gold allocation of 5% to 8%. “Gold may not offer the outsized return potential of private investments, but the metal holds a set of attributes that are increasingly hard to ignore,” according to McLaughlin. Those attributes include the metal’s resilience amid economic uncertainty and geopolitical unrest.

Thomas Winmill, portfolio manager at Midas Funds, believes most investors will benefit from a long-term gold allocation of 5% to 15%. Winmill specifically advocates investing in gold mining companies through a mutual fund.

Your risk tolerance and current mix of financial versus hard assets can guide you to an appropriate allocation, according to Winmill.

**Risk tolerance. **Keep your allocation percentage low if you tend to panic in volatile cycles. 1.

**Financial vs. hard assets. **Financial assets are stocks and bonds. Hard assets include tangible items like real estate, gold, collectibles, classic cars, and equipment. If you have no home equity and your wealth is primarily in financial assets, you can set your gold allocation higher. Or, if your home is paid for and more valuable than your stock portfolio, gold investing may not be necessary.

Vince Stanzione, CEO and founder at First Information, recommends a 20% gold allocation, specifically in physical gold or a gold ETF. Stanzione argues for a higher exposure to gold as a wealth protection strategy.
