If the Stock Market Crashes in 2026, I'm Making This 1 Investing Move Immediately

The article argues that long-term investors should continue buying stocks during a market crash, viewing declines of 5% or 10% as buying opportunities. It cites roughly 10% average annualized S&P 500 returns over 98 years and about 15.3% annualized returns for the Vanguard S&P 500 ETF over the past 10 years, while noting returns are not consistent year to year and past performance is not guaranteed.

Analysis

This is a behavioral argument, not a market-timing signal. The investable implication is that a precommitted rebalancing plan can turn volatility into incremental demand; it does not mean every drawdown is immediately cheap or that a crash has a short recovery path. In the first days of a selloff, volatility-control strategies, systematic trend followers and leveraged investors can add supply, overwhelming discretionary dip-buying. Over 1–3 months, whether that flow stabilizes matters more than the slogan: watch market breadth, credit spreads, earnings revisions and fund flows. Over 6–18 months, the key risk is a prolonged earnings or valuation reset that leaves a lump-sum buyer underwater despite the index’s long-run history.

The contrarian point is that investors often mistake historical index averages for a usable forecast. Broad-index exposure also inherits concentration and valuation risks that the article does not assess; a lower index level alone is not evidence those risks have cleared. The claim that crashes have bounced back is true of the cited historical experience, but timing, recovery duration and the investor’s liquidity needs determine whether an individual can hold through the path. No directional trade follows from this article alone; the more defensible edge is disciplined sizing and liquidity management.

Key Decisions for Investors

• Do not add broad equity risk solely because the S&P 500 falls 5–10%. For long-horizon mandates, use existing rebalancing bands to add to SPY or VOO in stages, with a separate liquidity reserve; avoid converting a planned allocation into an unbounded dip-buying commitment.
• Near term, treat a sharp selloff as a flow-risk event, not automatically a bargain: monitor credit spreads, earnings-revision breadth, volatility-control selling and fund flows before accelerating purchases. Stabilizing breadth and spreads would support adding; continued deterioration would argue for pacing buys.
• No standalone long or options position is warranted from this generic commentary. Reassess if earnings expectations weaken materially, credit spreads widen persistently, or index leadership narrows further; those developments would undermine the assumption that broad-market exposure is simply discounted.
• For any staged-buy plan, define the thesis falsifier in advance: a worsening earnings outlook or a liquidity need that shortens the holding horizon invalidates the premise that the investor can wait for recovery. Verify current index concentration, valuation and portfolio cash needs before changing exposure.
