We're Witnessing the Stock Market Do Something for Only the 3rd Time in 100 Years. History Says This Could Come Next

The article warns that AI-driven market concentration and elevated valuations may leave stocks vulnerable: the CAPE ratio is 40.1 versus a historical average of 17.4, while information technology accounts for 40% of S&P 500 value. South Korea’s market has fallen 37.1% from its June 22 peak; in the US, markets lost more than $1 trillion on October 30, with Intel down 29% and Alphabet down 12%. The author advises long-term investing, viewing drawdowns as potential buying opportunities, and keeping some cash amid uncertainty.

Analysis

The key risk is not simply that AI demand disappoints; it is that capex returns fall below the cost of capital while spending plans remain sticky. That would first pressure hardware and infrastructure suppliers, then force hyperscalers to justify deployment economics. A slower buildout could also weaken data-center power, cooling and networking demand, even if long-run AI adoption continues.

The exposures are not interchangeable. INTC combines execution risk with substantial manufacturing investment, making it more vulnerable if utilization or external foundry demand disappoints. SKHY is exposed to an inventory and pricing cycle: AI-related memory demand may cushion a downturn, but does not immunize it from a broad capex pause. GOOG faces a different test—whether AI features can preserve search economics and create incremental monetization, rather than merely shifting usage and adding costs.

Near term, sharp drawdowns can produce forced de-risking and correlated selling; they are not proof that AI demand has structurally rolled over. Over 1–3 months, watch hyperscaler capex guidance, memory pricing, and search monetization commentary. Over 6–18 months, the deciding evidence is realized returns on deployed infrastructure. High market concentration raises index downside sensitivity, while fiscal or monetary support may soften activity but cannot guarantee equity multiples. The contrarian point: a concentrated overseas market is a poor one-for-one signal for US earnings, and valuation extremes warn about long-horizon returns more reliably than next-week timing.

Key Decisions for Investors

• Prefer a relative-value screen over an outright AI-sector short: consider a dollar-neutral long GOOG / short INTC only if upcoming results show GOOG defending search monetization while INTC’s investment burden or utilization outlook worsens. Reassess on guidance; the pair thesis is falsified by accelerating search monetization deterioration or credible improvement in INTC utilization and returns.
• Do not chase downside in SKHY solely on the market drawdown. Track memory pricing, inventory and customer capex commentary over the next 1–3 months; a sustained deterioration in those indicators would strengthen the case to reduce exposure, while stable pricing would argue against treating AI demand as broken.
• For broad-market tail risk, consider a small, defined-risk QQQ put spread rather than an unbounded short, but only after checking implied volatility and event pricing. Maximum loss is the premium; avoid paying up if volatility already prices a severe correction. Trim or close if capex guidance stabilizes and earnings revisions broaden beyond a few mega-cap names.
