In March 2020, the average "diversified" portfolio behaved less like a basket and more like a single bet. Stocks fell. Bonds wobbled. Gold dipped before bouncing back. The international slice did not save anyone. The lesson, again, was the one most investors learn the hard way: spreading money across many things isn’t the same as spreading it across many behaviors. Non-correlated assets are the fix.
Most portfolios are more correlated than their owners realize. Pile up enough stocks, sector ETFs, and "alternative" funds, and you can still wake up to find them all moving together when it counts. The textbook 60/40 used to handle this by leaning on bonds for offset. Then 2022 broke the rule. Stocks and bonds dropped at the same time, the worst joint year for the pair in nearly a century. The fix isn’t more assets. The fix is assets that move to a different drumbeat.
This guide covers what non correlated assets are, how correlation actually works, which asset classes qualify, and how to access the few that pair low correlation with steady income.
What Are Non-Correlated Assets?
Non-correlated assets are investments whose returns don’t move in step with the broader market. When the S&P 500 drops 20%, an uncorrelated asset might rise, fall, or stay flat. The point is that its path isn’t tied to what stocks are doing.
Correlation is measured on a scale from -1 to +1.
- +1 means two assets move in perfect lockstep. When one rises 5%, the other rises 5%.
- -1 means they move in perfect opposition. One up, one down, every time.
- 0 means there’s no link. The assets ignore each other.
In practice, you almost never see a true 0. The goal is to get close. An asset with a correlation of 0.1 to the S&P offers most of the benefit of full non-correlation. An asset with a correlation of 0.7 is just a stock in disguise.
This is also the difference between non-correlated and negatively correlated. A negatively correlated asset zigs while stocks zag. A non-correlated asset does its own thing entirely. Both have a role in a portfolio. They don’t play the same role.
Why Correlation Matters for Your Portfolio
The pitch for diversification used to be simple: own more things, take on less risk. The reality is messier. Owning a hundred stocks across 10 sectors does almost nothing if all hundred fall together when the market drops. The honest version of modern portfolio theory says it plainly. Real diversification works through correlation, not through count.
This is the part most investors miss. The guard against a market crash isn’t the number of holdings. It’s whether those holdings move on different schedules.
A few free tools make this easy to check. Portfolio Visualizer lets you input your holdings and see how they move against each other. Guggenheim's correlation map shows how major asset classes have tracked one another over various time frames. Both are worth an hour. You may find that your portfolio is far less spread out than your statement suggests.
Ray Dalio's "Holy Grail" of Investing: 15 Uncorrelated Assets
Ray Dalio runs Bridgewater Associates, the largest hedge fund in the world. He’s written at length about what he calls the Holy Grail of investing. The idea is unlovely in its simplicity.
In his book Principles, Dalio writes that with 15 to 20 good, uncorrelated return streams, an investor can cut portfolio risk by roughly 80% without giving up expected returns. That ratio, he argues, is the closest thing to a free lunch finance offers. Five times the return per unit of risk. It’s achieved not by picking better single investments, but by combining a handful of decent ones whose paths do not overlap.
Dalio's own framing is sharper than most. "Individual assets within an asset class are usually about 60% correlated with each other," he writes, "so even if you think you're diversified, you're not." Owning ten tech stocks isn’t diversification. Owning 10 things that stop working in the same kind of market isn’t diversification. It’s one bet, dressed up as 10.
This idea is the foundation of Bridgewater's All Weather strategy, which spreads risk across economic environments rather than asset classes alone. The full strategy is more involved than any retail investor can copy. The core insight, though, is portable. Portfolio construction matters more than picking the best asset.
Most investors spend their energy chasing the next great stock. Dalio spent his career chasing the next uncorrelated stream. The math says he was right.
Examples of Non-Correlated Assets
The list of true uncorrelated assets is shorter than most articles suggest. These are the ones that hold up under pressure:
- Real estate: Direct ownership and certain private real estate funds offer income tied to local property markets, which often move on a slower clock than stocks. Public REITs, by contrast, trade like equities.
- Gold and precious metals: Long viewed as a hedge against inflation, currency stress, and political upheaval. Gold pays no income. Pure store of value.
- Commodities: Oil, natural gas, copper, and crops follow supply and demand more than stock-market mood. Volatile, but uncorrelated to equities over long periods.
- Private credit: Loans made outside the banking system to businesses. Returns come from interest, not market price. Income-generating, but illiquid.
- Farmland: Tied to crop prices and land values. Income is real but small per acre, and access for retail investors is limited.
- Art and collectibles: Wine, watches, classic cars, fine art. Returns come from price growth alone. No cash flow, hard to value, and even harder to sell quickly.
- Litigation finance: Funding lawsuits in exchange for a share of any award. Returns are tied to legal outcomes, not markets. High potential, high variance.
A point that gets lost in most lists like this. Only some of these produce income. Gold, art, collectibles, and farmland mostly deliver returns through price growth. Real estate, private credit, and litigation finance can produce cash flow, though access is often gated by high minimums.
That distinction matters. A portfolio of pure price-growth plays still has to wait for a sale to realize a return. A portfolio of income-producing uncorrelated assets pays you while you wait. That’s rare in this space, and it sets up the case for the strongest of them all.
Why Music Royalties Are One of the Strongest Non-Correlated Assets
Most assets on the list above offer diversification. Few combine low correlation with steady income and a proven track record through multiple downturns. Music royalties check all three boxes.
Royalties are payments owed to whoever holds the rights to a song. Every time a track is streamed, played on the radio, performed at a venue, or licensed for a TV ad, money flows back to the rights holder. Once the rights are owned, the income arrives without further work. The system runs in the background.
Streaming Revenue Doesn't Follow the Stock Market
Music consumption is driven by listening habits, not earnings calls. People don’t stop streaming during a recession. They may even stream more.
The data backs this up. Global recorded music revenues hit $31.7 billion in 2025, the 11th straight year of growth. Streaming alone topped $22 billion. Paid subscribers reached 837 million worldwide. None of those numbers were dragged down by the 2022 rate hikes, the 2020 pandemic shutdown, or the inflation shock that followed. The stock market was. Music was not.
Earlier research from Toptal compared music IP to broader macro signals and found steady growth through the Great Recession. Mills Music Trust, a publicly traded music royalty trust, has run with a beta of -0.65 against the broader market, meaning it has tended to move in the opposite direction of stocks. That kind of separation is what investors hope for when they hear the phrase "non-correlated."
Income-Generating, Not Just Diversifying
This is the part that sets music royalties apart from most of the list above. Gold sits in a vault. Art hangs on a wall. Both can grow in value over time, but neither pays a dollar while you hold it.
Music royalties pay quarterly. The income comes from millions of small uses across hundreds of platforms, gathered and sent out by collection groups. A typical catalog throws off a steady stream of cash, year after year.
Being both uncorrelated and income-producing is rare. Being uncorrelated, income-producing, and proven through multiple downturns is rarer still.
Institutional Money Is Already Here
The pension funds, endowments, and family offices figured this out before retail investors did. The Church of England's investment fund went on record citing 8% to 10% expected returns from music royalties. The Church Pension Fund in the U.S. has been buying royalty stakes in catalogs from artists like Bob Marley, Stevie Nicks, and Prince. Goldman Sachs has been writing institutional research on the music industry for years.
Then there’s Blackstone. In July 2024, the largest alternative asset manager in the world acquired the Hipgnosis Songs Fund for $1.58 billion, picking up a 45,000-song catalog. The same year, Blackstone launched a $1 billion partnership with Hipgnosis Song Management to keep buying.
The smart money isn’t testing the asset class. It’s loading up on it.
One nuance worth noting. Royalty cash flows are uncorrelated. Royalty valuations are not entirely. When interest rates rise sharply, the price someone is willing to pay for a future stream of cash flows can drop, because the discount rate goes up. The income keeps coming. The mark-to-market value can wobble. For investors holding for cash flow, this matters less. For investors trading positions, it matters more.
Risks to Consider With Non-Correlated Assets
No asset class is risk-free. The list of uncorrelated assets includes some that are genuinely volatile on their own, even if they move out of step with stocks. Crypto, collectibles, and early-stage venture all qualify as uncorrelated and risky at the same time.
Liquidity is the other catch. Many of these assets are private. Selling a piece of farmland or a stake in a hedge fund isn’t the same as clicking "sell" on a brokerage app.
Then there’s the crisis correlation problem. Plenty of assets look uncorrelated during calm markets and then converge when stress hits. The right test isn’t how an asset performed last year. It’s how it performed in 2008, in March 2020, and in 2022. If the answer is "it dropped with everything else," it’s not really providing the cover investors hope for.
This is one place music royalties stand apart. Streaming revenue grew through COVID and the 2022 rate hikes because people kept listening. Listening habits do not follow the business cycle. That said, no asset is risk-free. Single catalog performance varies. Genre popularity shifts. Streaming platform economics can change. Catalogs anchored in older, deeper material with broad genre exposure tend to be more stable than catalogs riding a single recent hit.
How to Find and Evaluate Non-Correlated Assets
A simple checklist before adding any so-called uncorrelated asset to a portfolio:
- Is the income tied to fundamentals unrelated to stocks and bonds? Music royalties earn from streams. Real estate earns from rent. Gold earns from nothing, which is also the point. Pin down what drives the cash flow.
- What is the historical correlation coefficient? Tools like Portfolio Visualizer let you measure this directly against the S&P 500 and other benchmarks. Do the work. Do not assume.
- How did the asset perform during 2008, 2020, and 2022? This is the crisis correlation test. If an asset dropped 30% in March 2020 alongside everything else, its correlation in good times was a mirage.
- What is the access and transparency profile? Many non-correlated assets, including private equity, hedge funds, and large farmland deals, require multi-million-dollar minimums and offer little visibility into the underlying holdings. Cheaper, clearer options exist for most asset classes.
The phrase "uncorrelated assets" gets tossed around carelessly in pitch decks. Honest review comes from running the numbers, not from accepting marketing claims.
How to Add Music Royalties to Your Investing Portfolio
Royalty Exchange is the marketplace for buying music royalty income streams. Investors get access to publishing royalty catalogs, the bundle that includes mechanical, performance, and sync income, with full data on past earnings, song-level performance, and revenue trends.
The process is straightforward:
- Browse listings: Each catalog includes detailed earnings history and song-level data. (Browse current listings).
- Run the analysis: Look at the last 12 months' earnings, the trailing trend rate, the age and depth of the catalog, and the genre mix.
- Bid: Auctions run on transparent terms. Winning bids close the deal directly with the seller through Royalty Exchange.
- Collect: Royalties pay quarterly, semi-annually, or monthly with full reporting on the underlying earnings.
A typical catalog yields in the mid to high teens. Many include long-tail income from songs that have been earning steadily for a decade or more. Catalog age matters. A song that has been earning for fifteen years is far more predictable than one that broke last summer.
For a deeper guide on what to look for, the Ultimate Guide to Buying Music Royalties walks through every factor. To start, create a free account.
The portfolio that holds up across cycles is not the one with the most names on the statement. It’s the one whose pieces stop holding hands when the market turns. Non-correlated assets are not a sideshow. They are the backbone of any portfolio built to survive whatever comes next. Music royalties are one of the few that pay you while they do their job.
