Stocks and bonds remain the foundation of many portfolios, but they don’t cover every investment objective. An investor may want income that isn’t tied directly to public bond markets, exposure to assets with different economic drivers, or a way to reduce reliance on daily stock-price movements.
That has pushed more capital toward private credit, private equity, infrastructure, real estate, commodities, and other alternative assets. Access is also expanding through private funds, interval funds, digital investment platforms, and wealth-management products aimed at individuals rather than large institutions.
Yet wider access doesn’t automatically make an investment suitable. Alternatives can involve long holding periods, limited reporting, layered fees, uncertain valuations, and restrictions on when investors can withdraw their money. The potential return must be weighed against those disadvantages.
For accredited investors and experienced portfolio builders, the useful question isn’t, “Which alternative investment is best?” A better question is, “What am I being paid for, what could go wrong, and how does this fit with the rest of my portfolio?”
Start With the Investment Objective
Before comparing funds or asset classes, define the job the investment needs to perform.
Are you seeking regular income? Long-term appreciation? Inflation protection? Lower sensitivity to stock-market swings? A combination of several goals?
The answer narrows the field. A private-credit fund designed to make quarterly distributions serves a different purpose from a venture-capital fund that may produce no cash flow for years. A commodity position may help offset inflation risk, but it won’t necessarily provide dependable income. Infrastructure can offer both income and appreciation, although results depend on the type of assets, financing structure, and regulatory environment.
Investors researching alternative investments for accredited investors should begin by writing down five constraints:
- Target return
- Desired level of income
- Acceptable holding period
- Need for liquidity
- Maximum tolerable loss
Be specific. “I want diversification” isn’t enough. Diversification can mean reducing stock-market exposure, spreading risk across industries, adding inflation-sensitive assets, or holding investments with different sources of return.
Without a defined purpose, it’s easy to select an impressive-sounding fund that doesn’t solve the portfolio problem you actually have.
Why Alternative Investments Are Drawing Attention in 2026
Private-market assets have grown substantially, and forecasts suggest that growth will continue. Preqin projects global alternative-investment assets under management will reach $29.22 trillion by 2029.
The same forecast projects that private-equity assets under management could rise from $5.80 trillion in 2023 to $11.97 trillion in 2029. Private-debt assets are projected to increase from $1.50 trillion to $2.64 trillion over that period.
Investors remain optimistic about the return potential. In Adams Street Partners’ 2025 survey, 85% of participating limited partners expected private markets to outperform public markets over the long term.
That confidence deserves attention, but it shouldn’t replace independent analysis. Private assets aren’t priced on an exchange every second. Reported returns may appear smoother partly because valuations are updated less frequently. An investment that looks less volatile on paper may still carry substantial economic risk.
Growth also creates competition. When too much capital pursues a limited number of deals, managers may accept weaker terms, use more leverage, or pay higher prices. Investors should examine whether expected returns still justify the illiquidity and complexity involved.
Comparing the Main Alternative Asset Classes
Each alternative asset class has its own return drivers, risks, fee structures, and cash-flow profile. Comparing them on the same set of factors makes it easier to spot trade-offs.
Private Credit
Private-credit funds lend directly to businesses, finance assets, or purchase privately negotiated debt. These strategies may offer floating-rate income and yields above publicly traded corporate bonds.
The sector has expanded rapidly. According to the International Monetary Fund, the global private-credit market reached $2.1 trillion in assets and committed capital in 2023. Roughly 75% of those assets and commitments were concentrated in the United States.
The income can be attractive, but higher yields usually reflect higher risk, limited liquidity, or both. Investors should study borrower quality, loan seniority, collateral, default history, and the manager’s experience handling troubled loans.
Interest-rate exposure also cuts two ways. Floating rates may raise fund income when benchmark rates climb, but they also raise borrowers’ financing costs. The IMF found that more than one-third of private-credit borrowers had interest expenses above their current earnings after benchmark rates increased.
The Bank for International Settlements reported that outstanding private-credit loan volumes grew from roughly $100 billion in 2010 to more than $1.2 trillion. Rapid growth makes underwriting discipline especially important.
Private Equity
Private-equity funds buy interests in privately held companies, often with the goal of improving operations, expanding the business, and selling the investment later.
These funds may produce strong long-term gains, but investors often commit capital for seven to 12 years. Cash flows can be unpredictable. Capital may be called over several years, while distributions depend on when portfolio companies are sold or refinanced.
Fees are another major consideration. Investors may pay annual management fees, performance-based carried interest, administrative expenses, and charges at the portfolio-company level. Ask for a complete estimate of the total fee burden rather than reviewing the headline management fee alone.
Valuation deserves close review as well. Since private companies don’t trade daily, managers rely on comparable-company multiples, transaction data, discounted cash-flow models, and internal assumptions. Small changes in projected growth or valuation multiples can materially alter reported results.
Infrastructure
Infrastructure investments can include renewable-energy facilities, utilities, transportation systems, telecommunications networks, data centers, and public-service assets.
Many infrastructure assets produce contractual or regulated revenue, which may support steady cash flow. Some contracts also include inflation adjustments. However, infrastructure isn’t a single risk category. A mature toll road has a very different profile from a development-stage energy project.
Investors should ask:
- Is the project operating or still under construction?
- Are revenues contracted, regulated, or dependent on usage?
- How much debt is involved?
- Who bears construction-cost overruns?
- Could regulations or political decisions change the economics?
Long-duration assets can also be sensitive to interest rates. Higher financing costs may reduce project values, especially when the investment relies heavily on debt.
Private Real Estate
Private real estate can provide rental income, potential appreciation, and a partial hedge against inflation. Options range from individual properties and syndications to diversified funds holding apartments, industrial facilities, offices, hotels, or specialized assets.
Property type matters. Apartments respond to housing supply and household income. Hotels depend on travel demand. Offices face lease rollover and occupancy risk. Warehouses may benefit from logistics demand but can still be hurt by overbuilding or tenant concentration.
The property itself also needs examination. In the same way that homeowners may assess design trends with lasting value before committing money to renovations, real estate investors should distinguish durable improvements from features that look attractive today but may add little to long-term rent or resale value.
Review leverage, debt maturity dates, tenant concentration, lease terms, capital-expenditure needs, local supply, and the manager’s exit assumptions. A fund can own quality buildings and still produce poor results if it pays too much or uses an unsuitable financing structure.
Commodities
Commodities include energy, metals, agricultural products, and related investment vehicles. They can behave differently from stocks and bonds, particularly during inflationary periods or supply disruptions.
However, commodity investing comes with its own complications. Prices can be volatile, and returns may depend on futures-contract structures rather than changes in spot prices alone. Funds that continually replace expiring contracts can gain or lose money depending on the shape of the futures curve.
Commodity-related equities, such as mining or energy companies, aren’t direct substitutes for physical commodities. Their performance also depends on management decisions, labor costs, debt, taxes, and operating execution.
Investors should decide whether they want tactical inflation protection, long-term exposure to scarce resources, or an allocation to commodity-producing businesses. Those are separate strategies.
Venture Capital and Other Specialized Assets
Venture capital, specialty finance, litigation finance, royalties, farmland, timber, collectibles, and digital assets may also appear in alternative portfolios.
These investments can offer differentiated returns, but they may be difficult to value and even harder to sell. Some depend heavily on a small number of outcomes. Others require specialized knowledge that a generalist investor may not possess.
Avoid allocating simply because an investment is unusual. Novelty isn’t a return source.
A Due-Diligence Checklist for Alternative Investments
A polished presentation can make almost any fund look compelling. Due diligence should go beyond the projected return shown on the first few pages.
Understand the Source of Return
Ask the manager to explain how the investment makes money in plain language.
Does the return come from interest payments, rent, business growth, asset appreciation, leverage, fee income, or selling at a higher valuation multiple? How much of the projected result depends on favorable markets?
If the strategy can’t be explained clearly, don’t assume the complexity is evidence of sophistication.
Review the Valuation Policy
Find out who values the assets, how often valuations occur, and whether an independent firm reviews them. Ask how the manager handles assets that lack recent comparable transactions.
Optimistic valuations can inflate reported performance, reduce apparent volatility, and increase performance fees. Compare valuation assumptions with public-market benchmarks and recent transaction data where possible.
Calculate the Full Cost
Request a complete schedule covering:
- Management fees
- Performance fees or carried interest
- Acquisition and disposition fees
- Financing costs
- Administration expenses
- Fund-level and asset-level fees
- Early-withdrawal charges
- Related-party payments
A strategy must outperform by enough to cover every layer of cost.
Examine Liquidity and Redemption Terms
“Quarterly liquidity” doesn’t always mean investors can redeem all their shares every quarter. Funds may cap total withdrawals, delay payments, suspend redemptions, or satisfy requests on a prorated basis.
Match the stated lock-up period with your financial plans. Money needed for taxes, property purchases, business expenses, retirement withdrawals, or emergencies shouldn’t be committed to a fund that may hold it for years.
Evaluate the Manager
Review realized investments, not just current unrealized valuations. How did prior funds perform after fees? How many losses occurred? Did the manager meet projected timelines?
Also examine team turnover, personal capital invested by the managers, disciplinary history, reporting quality, and how the firm handled previous periods of stress.
Building an Allocation Without Overcommitting
Alternative investments should be considered alongside the entire portfolio, not as a separate collection of deals.
An investor with a business, several rental properties, and private-company stock may already have significant illiquid exposure. Adding private equity or real estate could deepen concentration even if the securities account contains mostly public stocks and bonds.
Consider allocation at three levels:
- Total illiquid assets: How much of your net worth can remain inaccessible for several years?
- Economic exposure: Are multiple investments dependent on the same industries, interest rates, property markets, or consumer trends?
- Cash-flow timing: Could capital calls arrive when other investments stop making distributions?
Start with a modest allocation when evaluating a new manager or unfamiliar asset class. Diversify across managers, vintage years, strategies, and maturity periods rather than committing the full target allocation at once.
Regional differences also matter. The OECD reported that Asian pension funds allocated 8% of their assets to alternatives in 2024, compared with 37% in North America and 26% in Europe, the Middle East, and Africa. Those gaps may reflect differences in regulation, market maturity, institutional experience, and access—not simply different return expectations.
Warning Signs That Deserve a Closer Look
Walk away or investigate further when you encounter:
- Returns presented without net-of-fee figures
- Valuations that rise steadily despite weaker market conditions
- Vague descriptions of underlying assets
- Heavy use of leverage without stress-test results
- Redemption terms buried in legal documents
- Projected exits based on unusually high valuation multiples
- A manager with little personal capital invested
- Income distributions funded partly by new investor capital or asset sales
- Limited reporting on defaults, impairments, or unsuccessful investments
- Pressure to invest before reviewing the full offering documents
No single warning sign proves that an investment is unsuitable. Several appearing together, however, may indicate that the expected return doesn’t adequately compensate investors for the risks.
Conclusion
Alternative investments can broaden a portfolio beyond publicly traded stocks and bonds, but every potential benefit comes with a trade-off. Private credit may provide higher income while exposing investors to borrower defaults and restricted liquidity. Private equity may offer long-term appreciation but involve high fees and uncertain exit timing. Real estate and infrastructure can generate cash flow, though both remain sensitive to financing costs, valuations, and economic conditions. Commodities may help during inflationary periods but can experience sharp price swings.
The expansion of private markets through 2026 gives accredited investors more choices, not easier decisions. Evaluate each opportunity according to its return source, liquidity, valuation process, fees, manager quality, and place within your broader financial plan.
Above all, compare the potential reward with the risk you’re being asked to accept. An attractive projected return means little when the assumptions are unrealistic, the fees consume too much of the gain, or the holding period conflicts with your need for access to capital. A disciplined evaluation process won’t eliminate losses, but it can help you avoid investments whose risks were visible from the start.
Mirelith Norcroft is the kind of writer who genuinely cannot publish something without checking it twice. Maybe three times. They came to financial planning resources through years of hands-on work rather than theory, which means the things they writes about — Financial Planning Resources, Expert Analysis, Investment Strategies and Insights, among other areas — are things they has actually tested, questioned, and revised opinions on more than once.
That shows in the work. Mirelith's pieces tend to go a level deeper than most. Not in a way that becomes unreadable, but in a way that makes you realize you'd been missing something important. They has a habit of finding the detail that everybody else glosses over and making it the center of the story — which sounds simple, but takes a rare combination of curiosity and patience to pull off consistently. The writing never feels rushed. It feels like someone who sat with the subject long enough to actually understand it.
Outside of specific topics, what Mirelith cares about most is whether the reader walks away with something useful. Not impressed. Not entertained. Useful. That's a harder bar to clear than it sounds, and they clears it more often than not — which is why readers tend to remember Mirelith's articles long after they've forgotten the headline.
