If a Stock Market Crash Is Coming, Warren Buffett Says This Is the Smartest Move to Make Right Now

Since the S&P 500’s October 12, 2022 bear-market low, it has risen 118%, while the Nasdaq Composite has gained 165%, with the rally coinciding with the generative AI boom. The article warns that AI enthusiasm may invite dot-com comparisons, but notes the S&P 500 ultimately rose roughly fivefold from its March 2000 peak despite a roughly 49% decline and a lengthy recovery. It advocates staying diversified and focused on valuation and business fundamentals rather than trying to time the next crash.

Analysis

The useful distinction is between staying invested and staying concentrated. A broad index can recover while individual high-multiple companies never do; the dot-com analogy therefore supports diversification, not a blanket defense of today’s AI-linked prices. The cited fivefold index comparison is nominal and endpoint-dependent, and says little about the path, inflation-adjusted or dividend-inclusive returns, or the survival odds of a single stock.

The less obvious risk is correlated exposure: AI infrastructure suppliers and their customers can all depend on the same capex cycle. If data-center spending outruns monetization, order growth may weaken before the long-run AI opportunity disappears. That would make NVIDIA especially sensitive to changes in customer spending and forward expectations, while a broad index could also be vulnerable if a small group of mega-cap names drives returns. Berkshire Hathaway may offer a different company-specific exposure, but it is not a reliable short-term hedge against an equity drawdown.

Days: avoid trading the crash prediction itself. Over 1–3 months, watch NVIDIA guidance and evidence that deployed compute is producing customer returns, not just announced investment. Over 6–18 months, the key test is whether AI workloads support recurring demand and returns on infrastructure. The bullish case weakens if spending plans are cut or utilization and monetization disappoint; the broad-market resilience case weakens if earnings breadth deteriorates beyond AI leaders.

Key Decisions for Investors

• Keep strategic broad-equity exposure rather than making an all-in/all-out timing call, but rebalance if AI-linked concentration has become a dominant portfolio risk. The article’s historical analogy is not evidence that current prices are attractive.
• Treat NVIDIA as a capex-cycle exposure, not a proxy for AI adoption alone. Before adding, verify order/guidance trends against customer spending and evidence of workload utilization; reconsider the thesis if guidance weakens alongside capex plans.
• For a near-term risk overlay, consider a defined-cost broad-index put spread only where portfolio drawdown risk warrants the premium; avoid an outright short based solely on bubble comparisons. Reassess after earnings and major capex updates, and close or resize if breadth and earnings expectations stabilize.
• Use Berkshire Hathaway as a distinct equity holding only after assessing its own valuation and portfolio role—not as a guaranteed crash hedge. No relative-value trade is justified from this article alone without current valuation, exposure, and earnings data.
