If a Stock Market Crash Is Coming, History Says This 1 Strategy Has a Perfect Track Record

The S&P 500 has never produced a negative 20-year total return in the historical periods cited, while it was positive in 94% of 10-year periods since 1928. Reinvested dividends accounted for roughly 44% of its total return over the past 30 years; the article cites annual expense ratios of 0.03% for Vanguard’s S&P 500 ETF and 0.02% for State Street’s SPDR Portfolio S&P 500 ETF. It cautions that past performance does not guarantee future returns, despite arguing that long-term buy-and-hold investing may remain effective amid elevated yields and valuations.

Analysis

The article supports a strategic case for staying invested, not a tactical signal to add equity risk today. Its key limitation for a portfolio is that a positive long-run nominal index return does not ensure acceptable real returns, manageable drawdowns, or a good outcome over a shorter liability horizon. Starting valuations and the path of returns matter: elevated Treasury yields can both compete for capital and raise the discount rate applied to long-duration equity cash flows, making near-term multiple compression compatible with eventual recovery.

A further second-order effect is concentration. Continued flows into cap-weighted S&P 500 funds can reinforce the largest constituents’ price leadership, while leaving investors more exposed to a narrow set of companies and U.S. market-specific risks than the “500 stocks” label suggests. That is a portfolio construction issue, not a reason by itself to short the index. VOO and SPYM are close substitutes for broad S&P exposure; the small fee difference is unlikely to drive a meaningful relative trade absent other differences in execution or portfolio constraints.

Over days to months, rates, earnings revisions, and positioning—not a 20-year historical record—will drive returns. Over 6–18 months, sustained earnings growth and breadth would support the buy-and-hold case; deteriorating breadth or downward revisions alongside persistent high yields would challenge it. The contrarian point: historical resilience may be overused to dismiss entry-price and concentration risk, but abandoning equities based on crash warnings risks converting volatility into a permanent missed recovery.

Key Decisions for Investors

• Do not treat the article as a reason to time a wholesale equity exit or increase. Maintain strategic exposure consistent with portfolio drawdown limits; the piece adds no new near-term catalyst.
• Audit U.S. equity concentration by constituent and factor exposure. If the portfolio is already dominated by mega-cap growth, diversify new risk rather than adding another cap-weighted S&P position.
• If near-term drawdown protection is required, evaluate a defined-risk SPY put spread against the portfolio’s actual exposure and hedge budget; do not initiate solely on the article’s generic warning signs.
• Watch Treasury yields, earnings-revision breadth, and index concentration over the next 1–3 months. Reassess the bullish long-horizon thesis if yields remain restrictive while earnings expectations and market breadth deteriorate.
