That statement is not correct in general. Over long horizons (multiple decades) U.S. stocks have historically returned substantially more than bank CDs.
Key points
- Long-term outperformance: Broad U.S. equities (e.g., S&P 500 total return) have historically averaged roughly high single‑digit to low double‑digit nominal returns per year over the 20th and early‑21st century (commonly quoted near ~9–11% nominal depending on the exact dataset and period). Short‑term safe rates (T‑bills, money market rates and CD yields) have averaged much lower — typically in the low single digits to mid single digits over long periods.
- Why: The difference is the equity risk premium — investors require higher expected returns for holding the greater volatility and permanent-loss risk of stocks. CDs are safer (FDIC insured up to limits) so they pay less.
- Taxes and volatility matter: Interest on CDs is taxed as ordinary income, which reduces after‑tax yield. Stocks benefit from dividend tax preferences and long‑term capital gains treatment, and volatility can be smoothed by staying invested long term and reinvesting dividends.
- Exceptions exist: Over some specific decades or multi‑year stretches (for example, the 2000s “lost decade” for U.S. stocks, or periods of high short‑term interest rates in the late 1970s/early 1980s), CDs or short‑term instruments have outperformed equities. But those are the exception, not the long‑term rule.
If you’d like, I can:
- Pull exact historical average returns for a particular period (e.g., 1926–2024) and compare S&P 500 total returns vs. 3‑month T‑bills/CD proxy; or
- Show a decade‑by‑decade comparison so you can see the exceptions.
