The Nasdaq entered a correction on November 5, 2026, and the S&P 500 fell 4.36% the same day, even for people who never bought a Nasdaq fund. The reason is overlap: the biggest technology companies sit in both. Here is how to find out how much of your portfolio moves with the Nasdaq, how long corrections have lasted, and what the record says about waiting.

The short answer

A Nasdaq correction is a drop of at least 10% from a record high, and it hits your portfolio in proportion to the technology you own. The S&P 500 fell 4.36% on November 5, 2026, because its ten largest stocks make up roughly 40% of the index. Check your fund holdings before you react.

Update, November 6, 2026: Technology stocks bounced, and the Nasdaq stayed in correction territory. The Nasdaq rose 1.09% to 24,579.42 on November 6, up 264.43 points, according to Yahoo Finance, which reported that chip stocks rebounded after Thursday's selloff. The S&P 500 rose 0.31% to 7,376.86, had its worst week since June, and the Dow fell 0.46% to 51,285.73. The Bureau of Labor Statistics reported 165,000 October jobs, and December Fed hike odds rose to about 77%. One day of gains does not end a correction.

What is a Nasdaq correction, and how is it different from an S&P 500 correction?

A correction is a drop of 10% or more from a recent high. A bear market is a drop of 20% or more. The Nasdaq Composite tracks the stocks listed on the Nasdaq exchange, and technology companies carry heavy weight in it. The S&P 500 tracks 500 large US companies across all sectors, and the Dow tracks 30. On November 5, 2026, the three indexes fell by different amounts: the Nasdaq Composite fell 5.52%, the S&P 500 fell 4.36%, and the Dow fell 3.44%, according to CNBC. The ranking follows each index's technology share. The more technology and AI companies an index holds, the more it fell. A Nasdaq correction therefore signals trouble in one part of the market, and the damage to your account depends on how much of that part you own. See why the Nasdaq entered a correction after the midterms for the cause.

How much of my portfolio is in Nasdaq stocks?

Probably more than the name of your fund suggests. Most 401(k) accounts, target-date funds, and index funds hold the same large technology companies that drive the Nasdaq. Estimates of the top ten stocks' share of the S&P 500 in 2026 range from about 37% to 41% depending on the date and source, and the share reached a record near 40.7% in 2025, per Pensions & Investments data cited by Walnut Invest. Check the current weights on the S&P Dow Jones Indices page for the index. On a $10,000 S&P 500 fund, the 4.36% drop on November 5 was $436 on paper. On a $10,000 fund tracking the Nasdaq Composite, the 5.52% drop was $552. To check your own exposure, open each fund's page at your brokerage or plan provider and read the top ten holdings.

Where technology hides in a typical account
S&P 500 index funds hold the largest technology companies by weight. Total market funds hold them too. Target-date funds in a 401(k) often hold both. A single-sector or Nasdaq 100 fund holds them in a larger share. Only bond funds, cash, and international funds with little US technology hold few of them.

How long does a Nasdaq correction last?

The record spans months to many years, and the range matters more than any average. Three episodes show it:

2025: months
The Nasdaq fell almost 23% from its record through April 7, 2025, hit its low on April 8, and closed at a new record on June 27, 2025, per the Washington Examiner's report, about 11 weeks after the low.
2022: a full year of losses
The Nasdaq fell 33.1% in 2022, its fourth-worst year since 1971 according to The Motley Fool, as inflation and rising interest rates hit growth stocks.
2000: 15 years
After the dot-com peak on March 10, 2000, the Nasdaq did not close above that level until April 23, 2015, per an AFP report, which is 15 years later.

For the broader market, one analysis of S&P 500 data since 1950 counted 37 corrections of at least 10%, about one every 1.86 years, with an average of 196 days from peak to recovery, per Fox Business. Those are price figures, and dividends shorten recovery for funds that pay them.

The honest counterargument: should you sell before it gets worse?

The case for selling is real. The dot-com episode shows a technology-heavy index can take 15 years to regain its peak. Concentration is also higher now than in 2000: sources cite roughly 26% to 27% for the top ten stocks then, against 37% to 41% now. A portfolio that holds mostly technology has fewer places to hide.

The case against selling is also real. No one can reliably time the exit and the re-entry, and the market's best days often arrive close to its worst. See time in the market beats timing the market. A sale after a 10% drop turns a paper loss into a permanent one.

The fair resolution is a question about time, and the answer depends on your situation. Money you need within a few years does not belong fully in stocks, and that decision is best made before a drop. Money you will not touch for ten years or more has the time that the 2025 and 2022 recoveries needed. The honest limit: 2000 shows that time horizon is a condition, not a guarantee.

⚠
Treat the weight figures as estimates. Index concentration numbers come from secondary summaries and vary by date and source. The index provider's own factsheet has the exact current weights, and your fund provider's page shows the holdings you actually own.

What a beginner should actually do

  1. Look up your top ten holdings. Each fund provider lists them. Add up the technology names across your accounts.
  2. Compare your mix to your plan. Compare your current stock, bond, and cash shares to the targets you chose. See how to rebalance your portfolio.
  3. Check money with a near deadline. A home down payment or tuition due within a few years is a different risk than retirement savings. See where to keep cash when rates are high.
  4. Keep contributions on schedule. Regular purchases buy shares at lower prices during a correction.
  5. Avoid adding to a single theme as a reaction. Buying more of the sector that just fell raises the concentration the correction exposed. See whether the AI stock boom is a bubble.
💡
The actionable takeaway: read your fund's top ten holdings once. That list tells you whether a Nasdaq correction is a small event or a large one for your account, and it takes five minutes.

The quick version

  • A correction is a drop of 10% or more from a record, and a bear market is 20% or more
  • On November 5, 2026, the Nasdaq fell 5.52%, the S&P 500 fell 4.36%, and the Dow fell 3.44%, in order of technology weight
  • The top ten S&P 500 stocks make up an estimated 37% to 41% of the index, so index funds carry heavy technology exposure
  • Recoveries ranged from about 11 weeks after the April 2025 low to 15 years after the 2000 peak
  • S&P 500 corrections have occurred about every 1.86 years since 1950, with an average of 196 days from peak to recovery
  • Selling turns a paper loss into a permanent one, and holding only works if you do not need the money soon
  • Reading your fund's top ten holdings is the fastest way to measure your own exposure

A correction shows what you own. Reading the list takes five minutes, and it is worth doing before the next one.
