Wall Street's $3 Trillion Wipeout: What Investors Must Watch Next

Thursday's selloff erased nearly $3 trillion in U.S. market value — Wall Street's worst rout since the 2025 tariff shock, according to MarketWatch editor in chief Mark DeCambre. The decline wiped out Wednesday's postelection rally in a single session, and it spread far beyond AI stocks.

The S&P 500 closed Thursday around 7,354, sitting just above its 200-day moving average at 7,323. That line, a widely watched gauge of the market's longer-term trend, now marks the technical dividing line for the next leg of this story. A break below it could amplify the downtrend and further rattle confidence, DeCambre notes.

What does the selloff actually change for investors?

The damage wasn't confined to AI names. The numbers point to an everything selloff:

• 430 S&P 500 stocks declined — the carnage spread across the index, not just AI-related companies.
• 0 Dow components out of 30 finished the session in positive territory.
• Nearly 12% — how far the Nasdaq Composite has fallen below its October peak.
• 25.3 billion shares traded, the fourth-busiest session this year and 43% above average daily volume, per Dow Jones Market Data.

Overnight, the selling went global. Japan's Nikkei, Taiwan's Taiex and South Korea's Kospi all got hammered in sympathy with U.S. markets.

For practitioners, the key question is whether Thursday marked capitulation. The evidence is mixed. BTIG sees early signs of panic selling — but not the kind of widespread surrender typically associated with a durable market bottom. Fundstrat's Mark Newton, by contrast, thinks a sharp rebound could come as soon as Friday or Monday.

That distinction matters for anyone itching to buy the dip. A market due for a bounce isn't always one that's found a bottom. DeCambre's framing is blunt: "Stocks can always get cheaper."

What should investors watch?

Three things, per the MarketWatch analysis. First, whether the S&P 500 holds its 200-day moving average. Second, whether buyers return to semiconductor stocks, which have borne the worst of the selling. Third, whether any recovery extends beyond a handful of top-tier tech names.

Friday's October jobs report adds another variable. Economists expect just 59,000 jobs gained — hardly a booming-economy picture. But as MarketWatch's Jeffry Bartash explains, the U.S. labor market has been remarkably steady even if hiring remains sluggish. A surprise in hiring or wages could shift interest-rate expectations and trigger fresh volatility. After Thursday's rout, investors want evidence the economy is holding up, not another reason to worry.

Is Nvidia a bargain now?

Nvidia shares have fallen more than 24% from their record-high close in October, putting the AI chip giant squarely in bear-market territory. For investors who missed the run-up, MarketWatch's Britney Nguyen explains why some analysts believe the selloff has gone too far.

Cash buyers crowd the housing market

Away from equities, a record 10% of first-time homebuyers are paying entirely in cash, according to the National Association of Realtors. That forces a practical question: where is all that cash coming from? MarketWatch's Aarthi Swaminathan digs into the drivers and what the trend means for buyers who still need a mortgage — a cohort now competing against bids that skip financing altogether.

The bottom line for the week ahead: watch the 7,323 line on the S&P 500 and Friday's payrolls print. If the index holds and the labor data lands steady, Newton's quick-rebound scenario stays alive. If it breaks, the market may still need to suffer more before it bottoms.
