If I Could Tell Every Investor 1 Thing About Stock Market Crashes, It Would Be This

The article says a pullback may be due after nearly four years of a bull market, but cautions that market timing is nearly impossible and recommends staying invested while reviewing holdings and keeping some cash available. A 2025 Charles Schwab study counted 27 market corrections from November 1974 to February 2025, with six developing into S&P 500 bear markets. Historically, bear markets since 1961 averaged a 36% loss and lasted 409 days, compared with bull markets averaging 1,894 days and a 182.5% return.

Analysis

The useful implication is not that a pullback is overdue, but that calendar-based crash calls are poor timing signals. A drawdown becomes tradeable when fundamentals and positioning diverge: in a volatility shock, rising correlations and forced de-risking can temporarily punish profitable, liquid businesses alongside speculative names. That creates better entry points—but only if earnings and balance sheets remain intact.

The more exposed cohort in an AI-led reversal would be companies whose valuations require distant growth or whose customers must sustain unusually high infrastructure spending. The second-order risk is a capex feedback loop: if buyers slow spending, suppliers face weaker orders, while investors may also reassess the eventual monetization of AI investments. This is a conditional mechanism, not evidence that the current cycle is a bubble. Conversely, businesses with durable cash generation and limited refinancing needs may be relatively resilient, though not immune to market-wide selling.

The historical averages cited are not a forecast or a reliable timing tool: averages conceal materially different causes and recovery paths. Near term, a correction could trigger mechanical selling and wider dispersion; over 1–3 months, the key test is whether earnings revisions and credit conditions deteriorate; over 6–18 months, sustained capex returns and breadth matter more than the age of the bull market. The contrarian risk is sitting in excess cash while waiting for a crash that arrives late—or not at all. No directional trade follows from this article alone.

Key Decisions for Investors

• Do not reduce broad-market exposure solely because the bull market is older. Keep strategic index exposure; set a staged rebalancing plan in advance rather than trying to call the low.
• For a tactical relative-value watch, consider a beta-aware long RSP / short QQQ position only if market breadth deteriorates and earnings revisions weaken disproportionately among long-duration growth holdings. Reassess or exit if breadth improves and QQQ earnings estimates stabilize; this is not a standalone crash hedge.
• Keep any dry powder in liquid instruments such as SGOV and deploy it in tranches after a broad drawdown, but require confirmation that credit spreads are not still widening and forward earnings estimates are not falling sharply. Cash has an opportunity cost if markets continue higher.
• Before adding to AI-linked exposure on weakness, verify customer capex plans, order conversion, and evidence of returns on deployed infrastructure. A drawdown with stable revisions is a different setup from one accompanied by cancellations or persistent estimate cuts.
