The 20-Year Lens

Historically, the S&P 500 has not produced a negative total return over many long 20-year U.S. periods, depending on the data set and whether dividends are included. That is a powerful historical fact, but it is still history from one market. Over months or a few years, stocks can lose a lot. Over decades, risk has usually been rewarded, but the safer conclusion is to match stocks with a long horizon and a diversified plan, not to assume losses vanish automatically.

The worst 20-year return was still positive at roughly 6% annualized. The best was over 17%. When someone says stocks are "too risky," ask them: risky over what time frame? Over months, absolutely. Over decades, the record says no.
