Direct answer: US stocks fell sharply on Friday, October 30, 2026, closing a rough month for technology shares. The Nasdaq Composite had its biggest daily fall since June, and the Nasdaq 100 fell 3.5 percent, close to a correction. Investors sold technology stocks after a week of heavy spending plans from big tech companies raised doubts about how quickly that spending will pay off.
What happened
Reuters reported the Friday close on October 30, 2026. Chipmaker Intel fell about 29 percent, its worst day since the 1970s, after it forecast weaker fourth quarter revenue and warned it would burn cash this year. Sandisk, another chipmaker that has benefited from AI spending, dropped 13 percent. Microsoft, Meta, Amazon, and Google parent Alphabet, the four large companies at the center of the AI buildout, each fell 1 percent to 2 percent on Friday after larger falls earlier in the week.
The closing numbers confirmed the size of the drop. The Nasdaq Composite fell 2.86 percent to 25,437.00, the Nasdaq 100 fell 3.46 percent to 28,384.85, the S&P 500 fell 1.82 percent to 7,580.07, and the Dow Jones Industrial Average fell 1.09 percent to 51,770.31. The technology sector was the weakest part of the S&P 500, down 4.24 percent, while energy, consumer staples, utilities, health care, real estate, and materials rose.
The Nasdaq Composite is now down 7.8 percent from its closing high, and October was its worst month since March 2025. The Nasdaq 100 is on the brink of a correction, which means a fall of 10 percent from a recent high. The sell-off went beyond technology. Financial stocks were hit hard, with Goldman Sachs down 4 percent and Jefferies down 6 percent. Silver fell 6 percent on the day and is down 31 percent for the year, while gold fell 3.5 percent and is down 10 percent for 2026. Oil prices rose 2 percent, and Treasury bonds rallied as investors moved to safer assets. Bitcoin fell 3 percent after hackers took more than 6 billion dollars from Binance, as covered in our earlier post on that hack.
This Friday close is different from the premarket sell-off reported earlier in the day. That earlier post covered Amazon and Intel results before markets opened. This post covers the confirmed closing numbers for the full session and the month as a whole, which is why it is a separate story from the monthly Nasdaq sell-off covered earlier.
Why it matters for beginners
A stock index is a basket of many stocks, so when an index falls sharply, it means a broad group of companies lost value that day. The Nasdaq Composite includes many technology companies, so it falls hardest when tech shares are sold. The S&P 500 is broader, with 500 large US companies, so a smaller fall there shows that some parts of the market held up better.
A correction is a useful word to know. It means a fall of 10 percent or more from a recent high. It does not mean a crash, and it does not predict what happens next. It is a label for how far prices have fallen from their peak.
The deeper worry is about spending. The four large tech companies, sometimes called hyperscalers, have been responsible for more than a third of all capital spending by current S&P 500 companies over the past 12 months, according to Capital Economics, as reported by Reuters. Investors are now asking who will earn money from that spending, and who will not. When spending is partly funded by borrowing, higher interest rates can make that spending harder to justify, which is why rate expectations also matter for tech shares.
For a beginner, the main lesson is not to react to one day. Sharp falls can feel alarming, but they are part of how markets work, especially after a long rise. A single session does not tell you what to buy or sell.
What to watch next
Watch whether the new month brings calmer trading or more selling in technology shares. Watch the next earnings reports from large tech companies, because their spending plans and cash flow will stay in focus. Watch new inflation and jobs data, because those reports will shape expectations for interest rates, and rate expectations affect how investors judge expensive growth stocks. Also watch whether defensive parts of the market, such as energy and consumer staples, keep holding up while technology falls, because that split tells you whether investors are rotating to safer areas or selling everything.
FAQ
What is the difference between the Nasdaq Composite and the Nasdaq 100?
The Nasdaq Composite includes almost all stocks listed on the Nasdaq exchange, while the Nasdaq 100 includes 100 of the largest non-financial companies listed there. The Nasdaq 100 is more concentrated in large technology companies, so it can move more sharply on tech news.
Does a correction mean the market will keep falling?
No. A correction only describes how far prices have fallen from a high. Markets can recover, fall further, or move sideways after a correction. No single label predicts the next move.
Why did Intel fall so much more than the wider market?
Intel fell about 29 percent after it guided fourth quarter revenue below expectations and warned about cash burn, weak PC demand, manufacturing problems, and heavy spending to expand production. Company-specific news can move one stock far more than the wider index.
How does this affect a beginner investor?
A sharp day can change the value of a portfolio, but it does not change the basic steps for a beginner: understand what you own, keep costs low, avoid borrowing to invest, and avoid rushed decisions based on one day of headlines.
