The Stock Market Has Seen This Happen Only 2 Other Times in Over 150 Years, and History Has an Ominous Warning for Investors

The S&P 500 has gained nearly 120% since the bull market began in October 2022, while its CAPE ratio is above 40, the second-highest level on record; previous readings above 32 preceded major corrections in 1929 and during the dot-com bubble. Market breadth is narrow, with more than one-quarter of index stocks down at least 40% from their highs and nearly 60% below their 200-day moving averages. The article cautions against trying to time a correction, noting that missing the 10 best market days over 30 years would have halved returns, and advocates staying invested through dollar-cost averaging.

Analysis

The actionable signal is not CAPE alone; it is the mismatch between index-level strength and weak underlying participation. That makes cap-weighted exposure vulnerable to a small set of AI leaders: disappointment in expected returns on AI spending could pressure index earnings expectations and trigger passive outflows, while smaller constituents may not cushion the decline. NVDA, MU and PLTR are especially exposed to sentiment and positioning reversals, but the article provides no evidence that their operating outlooks have changed. The historical CAPE comparisons are a poor short-term timing tool: they identify valuation risk, not the catalyst or drawdown timing, and today’s rates, index composition and earnings mix differ from prior peaks.

Days to weeks: valuation warnings may lift demand for hedges, but a crowded defensive pivot can also make a sharp rebound costly to chase. Over 1–3 months, watch breadth, AI-related earnings/guidance and whether index gains broaden beyond the largest names. Over 6–18 months, sustained weak breadth alongside deteriorating AI spending returns would increase the risk of multiple compression; broadening earnings and participation would weaken the bear case. The article’s case for staying invested is sensible for long-horizon capital, but it does not justify adding risk indiscriminately at current valuations.

Key Decisions for Investors

• Do not short the S&P 500 or sell core holdings solely on CAPE. Keep strategic exposure and rebalance to policy weights; the historical valuation analogs do not supply a reliable entry date.
• For portfolios with near-term drawdown constraints, consider a modest, defined-premium 3–6 month SPY put spread rather than an outright short. Check implied volatility and hedge cost first; reduce or exit if market breadth improves persistently and AI leaders’ earnings/guidance remain intact.
• Treat NVDA, MU and PLTR as higher-beta sentiment exposures, not as a uniform fundamental short basket. Avoid adding to concentrated positions without checking valuation, earnings revisions and positioning; Burry’s disclosed bets are not a catalyst by themselves.
• Watch for a relative-value opportunity to rotate from cap-weighted SPY toward equal-weight RSP only if breadth starts to recover; that trade can underperform if leadership remains concentrated. Falsify the rotation thesis if equal-weight relative performance weakens and market participation continues to contract.
