The Best-Performing Asset Class of the Past 90 Years? The Data Leaves No Doubt. A decad

A decade-by-decade return study from NYU sends a clear message:

🔹 Stocks are the strongest long-term wealth creator.
With average annual returns of 10.3%, equities outperform every major asset class — including bonds, cash, real estate, and gold — across nearly a century.

Here’s what the data shows:

✅ Cash steadily loses purchasing power.
At 3.3% per year, cash only just matches inflation (3.2%) — safe, but not a path to building wealth.

✅ Bonds provide stability, not growth.
Long-term returns of 4.3% help smooth volatility, but fall far short of equity compounding.

✅ Real estate is resilient.
With 4.7% average returns, property holds up especially well during inflation — yet still lags stocks.

✅ Gold shines mainly during turmoil.
Huge gains in the 1970s (+28%) contrast with negative decades like the 1980s and 1990s.
A good hedge, but not a consistent generator of wealth.

👉 The real takeaway:
Diversification matters — but meaningful equity exposure is essential for real, inflation-adjusted returns.

After nearly 100 years of evidence, one conclusion stands firm:
Equities remain the foundation of long-term wealth building.
