The best assets to invest in depend on your goals, timeline, and comfort with risk, but most successful portfolios draw from a core set of asset classes: stocks, bonds, real estate, and cash equivalents. Stocks have delivered the highest long-term returns, averaging 9.81% annually since 1926 based on the S&P 500. Bonds and cash earn less but smooth out the ride. The right mix for you comes down to how long your money can stay invested and how much volatility you can stomach.
Stocks: The Strongest Long-Term Growth
Stocks represent ownership in companies, and over nearly a century of data, they’ve outperformed every other major asset class. That 9.81% average annual return since 1926 includes some brutal years: stocks lost 43.31% in their worst year (1931) and gained 53.99% in their best (1933). That range tells you everything about stocks. They reward patience and punish panic.
Most investors don’t pick individual stocks. Instead, they buy index funds or exchange-traded funds (ETFs) that hold hundreds or thousands of companies at once. A single S&P 500 index fund gives you exposure to 500 of the largest U.S. companies for an annual fee that’s often less than 0.10% of your investment. Broad market funds that include smaller companies or international stocks add further diversification.
Stocks are best suited for money you won’t need for at least five to ten years. If you’re investing for retirement decades away, a heavy stock allocation gives your portfolio the best chance of growing significantly. If you’ll need the money in two years for a house down payment, stocks carry too much short-term risk.
Bonds: Steady Income, Lower Risk
Bonds are essentially loans you make to governments or corporations. They pay you interest on a set schedule and return your principal when they mature. Long-term government bonds have averaged 5.42% annually since 1926, roughly half what stocks have returned, but with far less volatility.
The trade-off is straightforward: bonds won’t grow your wealth as fast, but they provide predictable income and help cushion your portfolio when stocks drop. Treasury bonds backed by the U.S. government carry virtually no default risk. Corporate bonds pay higher interest rates but come with the chance the company could fail to pay you back.
One specialized type worth knowing about is TIPS, or Treasury Inflation-Protected Securities. These adjust their value based on the Consumer Price Index, so your purchasing power stays intact even when prices rise. They’re useful if you’re worried about inflation eroding the value of your fixed-income holdings.
Real Estate: Income and Inflation Protection
Real estate has two things going for it that most other assets don’t: it generates rental income, and both property values and rents tend to rise alongside inflation. When the cost of living goes up, landlords can charge more rent, which means real estate income naturally keeps pace with rising prices.
You don’t need to buy a rental property to invest in real estate. REITs (real estate investment trusts) are companies that own and operate income-producing properties like apartment buildings, office towers, warehouses, and shopping centers. REITs trade on stock exchanges just like regular stocks, and they’re required to distribute most of their income as dividends. You can buy individual REITs or a broad REIT index fund for diversified exposure.
Physical real estate offers more control and potential tax advantages but requires significant capital, ongoing management, and the willingness to deal with tenants and maintenance. REITs give you the economic benefits of real estate ownership without those responsibilities.
Cash Equivalents: Safety and Liquidity
Cash equivalents include high-yield savings accounts, certificates of deposit (CDs), money market funds, and Treasury bills. These are the safest assets you can hold. They won’t lose value in a market downturn, and you can access your money quickly.
The downside is that returns are modest. Treasury bills have averaged less than 4% annually over the long term. As of early 2025, the best CD rates sit around 4% to 4.20% APY, with short-term CDs offering the highest yields. High-yield savings accounts pay in a similar range.
Cash equivalents are the right home for your emergency fund and any money you’ll need within the next year or two. They’re not designed to build wealth over decades, because their returns often barely keep up with inflation. But they play a critical role as a financial safety net.
Gold and Commodities: Inflation Hedges
Gold is a physical asset that tends to hold its value over long periods, making it a popular choice during times of economic uncertainty or rising inflation. You can buy physical gold, invest through a gold ETF, or purchase shares in gold mining companies. Gold doesn’t pay dividends or interest, so its return comes entirely from price appreciation.
Commodities more broadly include oil, silver, agricultural products, and other raw materials. These are real goods with persistent demand, and their prices often rise when inflation picks up. Most retail investors access commodities through ETFs or mutual funds rather than buying barrels of oil or bushels of wheat.
Neither gold nor commodities should make up a large portion of your portfolio. They’re volatile on their own and don’t generate income. Their value lies in diversification: they often move differently from stocks and bonds, which can reduce the overall ups and downs of your portfolio.
Alternative Investments
Beyond the core asset classes, a growing number of options are available to everyday investors. Private equity, venture capital, peer-to-peer lending, and real estate crowdfunding platforms all fall under the umbrella of alternative investments. These tend to have low correlation with stocks and bonds, meaning they can help diversify a portfolio further.
The catch is that many alternatives come with higher fees, less liquidity (your money may be locked up for years), and more complexity. Some are restricted to accredited investors, meaning you need a net worth above $1 million (excluding your primary residence) or annual income of at least $200,000. However, alternative investment funds have made some of these categories more accessible to retail investors in recent years.
Peer-to-peer lending, where you fund loans to individuals or businesses through online platforms, works similarly to bonds but carries higher default risk. It can offer attractive yields, but you should treat it as a small, speculative slice of your portfolio rather than a core holding.
How to Combine Assets Based on Your Risk Tolerance
No single asset is “the best.” What matters is the mix. A portfolio heavily weighted toward stocks will grow faster over long periods but will also swing more dramatically year to year. A portfolio leaning toward bonds and cash will be steadier but will generate lower returns.
A common framework breaks portfolios into a few profiles:
- Aggressive: 80% or more in stocks, with small allocations to bonds and alternatives. Suited for investors with a long timeline (20+ years) who can ride out sharp downturns without selling.
- Balanced: Roughly 50% stocks, with the rest split among bonds, real estate, and cash. This aims for a middle ground between growth and stability.
- Conservative: Heavily weighted toward bonds, cash equivalents, and other fixed-income assets, with a smaller stock allocation. Appropriate for people nearing retirement or those who need access to their money relatively soon.
A traditional rule of thumb suggests subtracting your age from 110 or 120 to get your stock percentage, putting the rest in bonds and cash. A 30-year-old might hold 80% to 90% stocks; a 60-year-old might hold 50% to 60%. This is a starting point, not a rigid formula. Your actual comfort with risk, your income stability, and your specific financial goals all matter more than a single number.
The classic 60/40 portfolio (60% stocks, 40% bonds) offers solid inflation protection and reasonable safety, but it will likely underperform a stock-heavy portfolio over long stretches. The right allocation is the one you can stick with through both good and bad markets without making emotional decisions.
Where to Start
If you’re new to investing, a single target-date fund or a three-fund portfolio (a U.S. stock index fund, an international stock index fund, and a bond index fund) covers all the major asset classes in one simple package. You can open a brokerage account or an IRA and start with whatever amount you have.
As your portfolio grows and your knowledge deepens, you can layer in real estate through REITs, add a small gold or commodity allocation, or explore alternatives. The most important step isn’t picking the perfect asset. It’s starting early, investing consistently, and keeping costs low. A boring, diversified portfolio that you contribute to every month will outperform a sophisticated strategy you never get around to implementing.
