What did the last 95 years actually deliver for everyday investors in the three building blocks of any portfoliostocks, bonds, and cash? Spoiler: equities won by a wide margin, bonds earned a respectable but bumpier second place, and cash did what cash doeskept you liquid and (mostly) near inflation. But the real story is richer, full of wild decades, surprise leaders, and a few “are we sure this is diversified?” moments. Let’s unpack the evidence with a clear-eyed, common-sense tour of the data.

Where the Numbers Come From

For a century-scale view, the go-to dataset combines updates from NYU Stern’s Aswath Damodaran (annual returns since 1928 for the S&P 500, 10-year Treasuries, and 3-month T-bills) and the long-standing SBBI (Stocks, Bonds, Bills & Inflation) series popularized by Ibbotson/Morningstar. These are the backbone of most “long-run” charts you’ve seen.

As a quick pulse check on cash yields (T-bills), we also look to the Federal Reserve’s FRED database, which traces short-term Treasury rates back to the 1930s.

Headline Results: 95 Years in One Glance

From 1928 through 2024, nominal annualized returns line up roughly as follows: U.S. large-cap stocks about ~10%, U.S. Treasury bonds around ~4.5%, and cash (3-month T-bills) about ~3.3%. These numbers come from the most recent update of the Damodaran series and a synthesis by Ben Carlson, who reprints and explains the dataset each year.

What about after inflation? Global and U.S. yearbook studies suggest long-run real returns of roughly ~6–7% for stocks, ~1–2% for bonds, and about ~0–0.5% for cash over very long horizons. Those figures flex by window, but they’re directionally consistent with the UBS Global Investment Returns Yearbook and other long-run surveys.

Inflation itself averaged around the low-3%s over the last century, with a recent post-pandemic spike and subsequent retreat toward the U.S. Federal Reserve’s 2% goal by late 2024–2025context that matters when converting nominal returns into purchasing power.

Decade-by-Decade: Same Game, Different Seasons

1930s: A brutal start for stocks (Great Depression), while high-quality bonds delivered ballastas you would hope in a deflationary bust.

1940s–1950s: War, then boom. Equities recovered and compounded as industrial America re-tooled, while bonds were constrained by financial repression (policy-kept rates).

1970s: Inflation was the villain. Nominal bond returns were kneecapped by rising rates; stocks muddled along; cash sometimes looked smartespecially before tax.

1980s–1990s: Disinflation + productivity = a golden run for both stocks and bonds. The 60/40 playbook felt unstoppable.

2000s: The “lost decade” for equities after the dot-com crash and Global Financial Crisisbonds rescued many allocation plans.

2010s: A monster equity decade (low inflation, low rates, expanding margins), while bonds quietly earned carry.

2020s so far: A pandemic whipsaw, then a steep 2022 where both stocks and bonds fellan unusual positive stock-bond correlation regimesetting up the cash comeback as T-bill yields ripped higher.

“Cash Beat Everything” More Often Than You Think

Over the past 95+ years, cash has occasionally outpaced both stocks and bonds in one-year windowsrare, but not unheard of. Ben Carlson counts 14 such years since 1928, including the rate-shock year of 2022. Bonds have topped stocks 35 times; cash has topped stocks in 31 years. That’s a great reminder: leadership rotates, and your time horizon matters.

Volatility, Drawdowns, and Your Gut

Equities earned the highest long-run return, but at the cost of the deepest drawdowns (multiple >-40% episodes). Long Treasuries can also suffer double-digit declines when rates rise fast (2022 was historically bad for core bonds). Cash, while steady, struggles to outrun inflation over the long arc. None of this is shocking; it’s the “risk premium” made visible.

If you’re tempted to “trade around” volatility, decades of evidence show most individuals underperform buy-and-hold by chasing heat and timing badly; the classic Barber & Odean study is still a cautionary tale.

The 60/40 Portfolio: Still a Workhorse

Despite periodic obituaries, a simple 60% U.S. stocks / 40% U.S. bonds mix has delivered solid risk-adjusted results across many regimes. 2022 was a gut-check, but the broader record across cycles remains compelling in long-run market guides. The key is staying the course through correlation shocks rather than abandoning diversification at the worst moment.

Nominal vs. Real: Why Inflation Turns “Good” Into “OK”

Long-term nominal figures (10%, 4–5%, 3% for stocks/bonds/cash) feel generous until you adjust for inflation. After inflation, stock returns look like 6–7% real, bonds around 1–2%, and cash near zero over ultra-long windows. That’s why equities dominate multi-decade wealth building, while bonds and cash shine in different, shorter jobs (income, ballast, liquidity).

Correlation Regimes: When Diversification Takes a Holiday

Stock-bond relationships aren’t fixed. In low, stable inflation environments, they often offset (negative correlation), but in inflation shockslike 2022they can move together (positive correlation), reducing diversification exactly when you want it most. Understanding that regime-dependence helps set expectations for risk and rebalancing.

What “Common Sense” Allocation Looks Like

1) Match Assets to Time Horizons

Money you need in the next 0–2 years? Keep it in cash-like instruments (T-bills, money markets). 3–7 years? Mix of high-quality bonds and some equities. 8+ years? Equities dominatebecause history favors risk assets over full market cycles. That simple ladder is the practical translation of the 95-year record.

2) Keep It Simple (and Repeatable)

Ben Carlson’s whole premisesimplicity beats complexityfits the data: stocks, bonds, and cash do the heavy lifting. Fancy doesn’t have to mean better; rules you can follow beat optimal strategies you can’t stick with.

3) Rebalance Like a Gardener, Not a Gambler

Rebalancing trims winners, waters laggards, and keeps risk from drifting. It also forces you to buy what feels uncomfortable (usually what just fell). Market guides and community research consistently show this discipline is a main source of “behavioral alpha.”

4) Expect the Unexpected

Each decade serves a different dish. Sometimes cash wears the crown. Sometimes bonds deliver the hero’s arc. Over full cycles, equities winbut they demand patience, diversification, and an iron stomach during deep setbacks.

Frequently Asked (Smart) Questions

“If stocks average ~10% a year, why don’t I see 10% every year?”

Because averages hide volatility. A handful of big up years often account for a large chunk of long-run gains; miss them, and your compounded return craters. That’s why timing is so hard and staying invested is so valuable.

“Isn’t cash safer?”

Cash is stable nominally, but inflation risk is real. Over decades, purchasing power erosion is the hidden fee of sitting out the market. In long-run studies, cash rarely keeps up with inflation after taxes.

“What if I just buy when markets ‘look cheap’?”

Valuation matters, but evidence suggests most investors don’t execute timing well. A better plan is to automate contributions, rebalance on a schedule, and use valuation more as a risk-management dial than an on/off switch.

Key Takeaways in One Page

• Equities delivered the highest long-run return (~10% nominal), but with the deepest drawdowns.
• Bonds provided income and diversification, with long-run ~4–5% nominal and regime-dependent protection.
• Cash preserved options and smoothed nerves, but rarely beat inflation over full cycles.
• Inflation is the great equalizer: real returns are what matter for goals.
• Behavior often beats brilliancesimple allocations, steady contributions, and rebalancing win.

Conclusion

Ninety-five years of data don’t promise the next year’s return, but they offer a reliable map: own equities for long-term growth, own high-quality bonds for income and balance, keep cash for near-term needs. Add patience, rebalance regularly, and you’ve captured the “wealth of common sense” that markets have been offering all along.

Experiences & Field Notes: Putting 95 Years to Work (≈)

Case Study #1: The “Weekend Warrior” Investor. In 2019, a 30-something professional started investing $500 a month into a 70/30 index mix. By 2022, their equity sleeve fell hard while core bonds also slumpedemotionally, it felt like diversification “failed.” The saving grace was a small cash bucket covering 12 months of expenses and an autopilot contribution plan that kept buying through the drawdown. By late 2023–2024, the combination of cheaper entry points and rising coupon income refilled the hole. Lesson: small, boring systems (cash cushion + auto-invest + scheduled rebalancing) beat big, brilliant predictions.

Case Study #2: The Pre-Retiree’s Glidepath. A 58-year-old entered 2020 with an 80/20 stock-bond split and a five-year retirement target. After a goals review, they built a “spending ladder”: two years of expenses in T-bills/money market, three years in short/intermediate Treasuries, and the rest in a global stock index. When 2022 hit, their paycheck came from T-bills rather than forced equity sales. By 2024, equities had healed while the bond sleeve rolled into higher coupons. Lesson: time-segmentation transforms scary volatility into routine cash flow management.

Case Study #3: The Over-Tweaker. Another investor tried to “optimize” by toggling between growth and value, then switching funds after each headline. Over three years, they racked up taxable gains, higher costs, and missed a few sharp upswingsclassic behavior gap stuff. A reset to a two-fund total-market/total-bond core plus an annual rebalance improved performance and sleep quality. Lesson: fewer moves, bigger wins. Decades of research show frequent trading erodes returns for most individuals.

Case Study #4: Valuation as a Dimmer, Not a Switch. A foundations committee wanted to “de-risk” after a strong run. Instead of binary in/out calls, they set bands: if equity valuations rose above historical ranges, they would gently tilt 5–10% toward quality bonds; if valuations fell below, they’d tilt back. That policy harvested volatility without inviting timing regrets. Lesson: let valuations guide rebalancing, not wholesale market timing.

Case Study #5: The “Cash is King” Fallacy (Over Decades). After a rough bear market, one family moved most assets to cash and waited for “clarity.” Years later, inflation quietly clipped purchasing power, while equities compounded from the sidelines. Their eventual re-entry (in stages) highlighted the true role of cash: liquidity and short-term safety, not long-term growth. Lesson: cash wins sprints, not marathons.

Bottom line: The last 95 years reward patience and process. Own stocks for growth, bonds for resilience, cash for flexibility. Write down your rules, automate what you can, and let markets do the compounding while you do… less.
