History Says This 1 Bear Market Move Is the Costliest Mistake Investors Can Make

The article argues that long-term investors should continue buying through selloffs rather than attempt market timing, noting U.S. bear markets have occurred roughly every six years over the past 150 years. Fidelity found that a $10,000 S&P 500 investment from 1988 to 2024 grew to $522,576, versus about $330,000—37% less—if the investor missed the market's five best days. It highlights the S&P 500's roughly 10% long-run annual return since 1928 and VOO's 15% annualized return since September 2010.

Analysis

This is retail-facing evergreen content rather than an investable information event; the named tickers have no demonstrated fundamental linkage to the thesis. The actionable implication is behavioral: broad “buy-the-dip” messaging can reinforce passive ETF inflows early in a correction, initially supporting the largest index constituents and potentially delaying price discovery in high-duration growth. That is a flow effect measured in days to weeks, not evidence that downside has been exhausted.

NDAQ is a cleaner conditional beneficiary than NVDA if volatility rises: elevated equity turnover, options activity, and market-data demand can improve near-term revenue mix, although a sustained risk-off episode could weaken IPO listings and capital-raising fees over the following 1-3 quarters. NVDA remains vulnerable to a market-wide de-rating because its valuation embeds a long-duration AI capex payoff; systematic dip buying may cushion drawdowns, but it does not protect against a hyperscaler capex-guidance reset or weaker accelerator pricing.

Contrarian view: the popular lesson to stay invested is correct for strategic allocators but can be harmful as a tactical signal when positioning is still crowded and volatility has not forced de-leveraging. A correction becomes more attractive after credit spreads, implied volatility, and equity breadth show capitulation; absent those conditions, passive inflows can simply be absorbed by concentrated mega-cap supply. There is no standalone trade from this article, and any tactical long should wait for independently observable flow and earnings data.

Key Decisions for Investors

• No event-driven position from this item. Maintain existing strategic beta rather than adding solely on a 10-20% index decline; require improving S&P 500 breadth and stabilization in high-yield credit spreads before increasing net exposure over a 1-3 month horizon.
• Place NDAQ on a volatility watch: consider a 3-6 month long only if sustained elevated equity/options volumes are visible without a material deterioration in the listings pipeline. Thesis is falsified by falling ADV and a meaningful reduction in IPO or issuer-services guidance.
• Avoid using NVDA as a generic dip-buy proxy for index weakness. Add only following confirmation from hyperscaler capex commentary and NVDA demand guidance; hedge any tactical long with QQQ puts or a QQQ short until breadth improves. A capex-guide cut or evidence of GPU price competition invalidates the long thesis.
• For portfolios needing tactical downside protection, prefer index hedges (SPY or QQQ puts, 1-3 months) over selling core holdings. Monetize protection if volatility spikes alongside credit-spread widening and breadth capitulation, rather than mechanically rolling hedges after the initial selloff.
