While many investors classify gold as a commodity, gold stands out from other commodities and alternatives, potentially offering more efficient diversification — a benefit that may support treating gold as a unique asset class, with a distinct and independent allocation of its own.
As portfolio construction evolves beyond the traditional “balanced” 60/40 stock and bond portfolio, investors are increasingly looking to add exposures with less traditional assets that can potentially add both diversification and uncorrelated returns. Based on gold’s historically low correlation with many traditional asset classes, an active allocation to gold may help to potentially improve strategic allocations and portfolio construction strategies for a wide range of portfolio risk profiles across a variety of full market cycles.
A commonly cited motivation to invest in broad commodities is to combat inflation, with commodities historically providing unique diversification and, generally speaking, positive average returns across various inflation environments. But not all commodities have performed similarly across all business cycles, and the extent of a commodity’s ability to offset inflation is more nuanced and dependent on the current or projected inflation regime.
Turning to today’s market, investors are contending with a high level of macro risk, low interest rates and high stock valuations, and inflation concerns are on the rise. Based on historical data, this backdrop may be positive for gold, with gold’s historical returns during periods of high inflation outperforming a basket of broad commodities.1
Moreover, as the chart below illustrates, certain commodities, such as oil, copper, and even silver, have historically been more cyclical than gold and have tended to have a higher correlation to market and economic cycles because their demand depends more on pro-cyclical consumption, meaning they may capture more of the upside movements in global equities, but they may also experience more of the downside when equities fall.

Understanding How to Compare Gold With Other Asset Classes
In conversations with investors, we are frequently asked how to compare gold with other commodities, liquid alternatives, and currencies. We often hear investors classifying gold as a commodity alongside other diversifying asset classes, such as oil, real estate, currencies, private equity and even a broad commodity index to gain exposure to gold. But gold frequently stands out from the pack of other commodities and alternatives, potentially offering more efficient diversification than many other sources — a benefit that may support treating gold as a unique asset class, with a distinct and independent allocation of its own.
Investors commonly access the commodity asset class by using broad commodity indices and passive strategies. This approach, however, should not be viewed as a substitute for an independent allocation to gold. In fact, based on three of the more prominent broad commodity indices, the gold allocation within a broad commodity index can range from 4% to 14%.2 This potentially leaves a portfolio underexposed to gold and some of its beneficial investment characteristics. Practically speaking, gaining gold exposure via a broad commodity index may offer investors access to some of gold’s diversifying and inflation-fighting benefits, but the relatively low exposure to gold may leave some potential benefits untapped.
When we compare gold with a major broad commodity index, we see that historically, gold has outperformed with less downside.

When discussing gold’s diversification benefits, the conversation often turns to other “liquid alternatives” that are frequently leveraged for their daily liquidity and low correlations to stocks and bonds. But broadly speaking, gold has historically maintained a lower correlation over time and has provided a more efficient source of diversification than many of those other assets, including REITs, liquid hedge fund strategies, and private equity proxies.
Since 2008, gold’s correlation to equities has trended lower, while other alternative asset classes have experienced a rise in their correlation to equities, potentially reducing the diversification benefits they provide to investors’ portfolios.

Currencies are another way that investors can manage volatility and inflation. With the evolution of technology, investors now have digital currencies, such as Bitcoin, to consider as an alternative for gold. But in our opinion, Bitcoin is not gold. In fact, Bitcoin’s extremely limited track record, exceptional volatility and speculative nature have yet to demonstrate that it can effectively transfer and preserve wealth like gold has the potential to do. And most central banks and other institutions still do not accept cryptocurrencies — such as Bitcoin — as a medium of exchange, further diminishing some of Bitcoin’s benefits relative to gold.
On a diversification and risk-adjusted return basis — especially during market downturns — Bitcoin historically is not comparable to gold, as seen in the following chart:

While innovation in the market is inevitable and welcomed, our stance is that both history and data have provided testament to gold’s historical store of value and virtues of diversification and liquidity — especially when compared with commodities, other alternative asset classes and cryptocurrencies, such as Bitcoin.
Based on today’s changeable markets and risks, gold’s role in a modern-day portfolio may be extending its reach, redefining its uses and benefits among the list of known portfolio diversifiers and traditional fixed income assets that investors have historically relied on to navigate risks and grow portfolio values.

Bloomberg Commodity Index A broadly diversified commodity price index distributed by Bloomberg Indexes that tracks 22 commodity futures and seven sectors. No one commodity can compose less than 2 percent or more than 15 percent of the index, and no sector can represent more than 33 percent of the index.
Bitcoin A peer-to-peer digital currency created in 2009 that offers the promise of lower transaction fees than those of traditional online payment mechanisms. Unlike government-issued currencies, Bitcoin is run and “regulated” by its own users using an infrastructure called “blockchain.”
Commodities A basic good used in commerce that is interchangeable, or “fungible,” with other commodities of the same type. Commodities are most often used as inputs in the production of other goods or services For example, crude oil is a commodity that is used to make motor fuels, heating oil and lubricants.
Correlation The historical tendency of two investments to move together. Investors often combine investments with low correlations to diversify portfolios.
Consumer Price Index (CPI) A widely used measurement of inflation at the consumer level that helps to evaluate changes in cost of living. The CPI is composed of a basket of consumer goods and services across the economy and is calculated by the US Department of Labor by assessing price changes in the basket of goods and services and averaging them. Core CPI is the same series, minus food and energy prices, since they are considered to be volatile enough to distort the meaning and usefulness of so-called headline CPI. The absence of food and energy means that the core series reflects long-term inflation trends more accurately.
Diversification A strategy of combining a broad mix of investments and asset classes to potentially limit risk, although diversification does not guarantee protection against a loss in falling markets.
Diversification Benefits In modern portfolio theory, diversification is an approach used to potentially reduce the overall risk of the portfolio by holding a mix of assets with low correlations to each other. The potential benefit of holding uncorrelated assets is that some investments may rise while others fall.
Down Market Capture The percentage of return that an asset captures when a market benchmark is down.
Downside Risk A given security’s potential to lose value if a prevailing market trend suddenly changes. The term also refers to the specific financial amount of the “worst-case” loss that that can occur in such sudden shifts.
Drawdown A specific decline in the stock market during a specific time period that is measured in percentage terms as a peak-to-trough move.
Drawdown Protection Investments that could help insulate an overall portfolio from a decline in stocks or other financial markets. Examples include cash or other investments that have historically held up relatively well in down or volatile markets, such as gold or equity put options.
Economic Cycle Periods of growth or contraction in the economy, typically called periods of expansion or recession. Different sectors and industries typically perform differently based on particular phases of the economy cycle.
FTSE NAREIT All Equity REITS Index The index is a free-float-adjusted market capitalization-weighted index that includes all tax-qualified REITs listed in the NYSE, AMEX, and NASDAQ National Market.

ICE BofAML US 3-Month Treasury Bill Index This is an unmanaged index that is comprised of a single U.S. Treasury issue with approximately three months to final maturity, purchased at the beginning of each month and held for one full month.
An overall increase in the price of an economy’s goods and services during a given period, translating to a loss in purchasing power per unit of currency. Inflation generally occurs when growth of the money supply outpaces growth of the economy. Central banks attempt to limit inflation — and avoid deflation — in order to keep the economy running smoothly.
