Nasdaq Slides Into Correction as Chip Stocks Slump

The Nasdaq slides into correction as chip stocks slump, and the main reason is a growing worry about whether huge AI spending will pay off. On Monday, November 2, 2026, the Nasdaq 100 closed 10.4% below its October 6 record, the technical definition of a correction. The Philadelphia Semiconductor Index (SOX) fell about 3.35%, and Microsoft, Apple, and Meta all closed lower.

This article explains the move in plain language and is information only, not investment advice.

What Happened on Monday, November 2?

The Closing Numbers

The Nasdaq 100 fell 1.39% to 27,989.82 after an early rally faded. The correction line was about 28,102, and the index closed roughly 112 points below it, which made it the first close in correction territory since July 29. The broader Nasdaq Composite fell 1.07% to 25,164.32, its lowest close since July 30.

What Is a Correction?

A correction means an index has fallen at least 10% from a recent high. It is not the same as a bear market, which is a drop of 20% or more, and it does not mean a recession is coming. Corrections are fairly common. Reports note that the Nasdaq 100 also closed in correction on March 27 and July 29 this year, and recovered to new records both times. That history does not guarantee a repeat.

How Bad Was the Chip Selloff?

The Semiconductor Index

The Philadelphia Semiconductor Index tracks major chip companies. Its 3.35% drop followed a 7.2% plunge on Friday, October 30, and it closed at its lowest level since April 29. It is now about 29.4% below its June 22 record of 14,655.29, and it fell about 15% during October alone.

The Biggest Losers

Memory and optical stocks took the hardest hits. Marvell Technology fell about 12.7% after announcing an all-stock deal for an optical-component maker, valued at around $115 billion including debt. Intel dropped about 8.8%, AMD about 7.5%, and Oracle almost 9%. Among memory names, Seagate fell about 7.9%, Western Digital about 7.5%, SanDisk about 6.6%, and Micron about 5.8%.

Which Big Tech Stocks Closed Lower?

Most megacaps ended the day in the red. Microsoft led the declines among them.

Apple reported earnings after the close, with revenue of $114.5 billion, which beat expectations. Even so, its shares dipped in after-hours trading because of a weaker margin forecast. You can read the company’s own Apple Newsroom results announcement for the full details.

Why AI Spending Worries Are Driving the Slide

The Core Question

Large technology companies have spent hundreds of billions of dollars on AI data centers and chips. Investors now ask a simple question: when will that spending turn into profit? Critics say earnings and cash flow have not yet caught up. Reports describe a market “repricing” of the AI return cycle, with AI-themed stocks down about 3% while the rest of the S&P 500 rose about 1% on the same day.

Recent Earnings Added Pressure

Alphabet had its worst day since going public after search advertising missed expectations, and Meta and Amazon also faced selling after their reports.

A Wave of Borrowing

Another worry is debt. Microsoft sold $25 billion of bonds last Thursday, its first US bond offering since 2017. Meta is reportedly preparing a multi-currency bond sale of at least $20 billion, Alphabet sold euro-denominated debt, and Oracle sold $10 billion of bonds while also issuing an equal amount of stock. Investors worry that funding AI with borrowed money raises risk if profits arrive slowly.

Memory Costs and Supply

Chip stocks were also hit by concerns about costs across the supply chain. Apple’s CEO called memory pricing unprecedented on its call, a reminder that surging memory prices squeeze device makers even as they help memory suppliers.

Why This Correction Looks Narrow

An important detail is how concentrated the damage has been. The standard S&P 500 fell only about 0.5% and sits less than 4% below its peak, while its equal-weight version rose about 0.73%. The Dow Jones Industrial Average also gained about 0.4%.

This gap happens because the standard S&P 500 is weighted by company size, so giants such as Nvidia, Microsoft, and Apple move it more. When large tech names fall while smaller companies rise, the average company may be doing fine even as headline indexes look weak. Following how sectors, indexes, and infrastructure interact takes broad technical literacy, and a Deep Tech Certification path can help learners understand the systems behind modern markets.

What Could Happen Next?

Reasons for Caution

• Momentum: The chip index closed below its 200-day moving average on Friday for the first time since June 2025 and failed to climb back above it on Monday.

• Failed rebound: Early gains on Monday disappeared by the close, which suggests low buyer conviction.

• Heavy borrowing: More bond sales could keep investors uneasy about returns.

Reasons for Patience

• History: The two earlier 2026 corrections ended with new record highs.

• Narrow damage: Most of the market has held up.

• Strong business results: Companies such as Apple posted record revenue even as shares slipped.

What Analysts Watch

Traders will follow upcoming earnings from chipmakers, any updates on AI spending plans, and bond market demand. Many will also watch whether the Semiconductor Index can recover above its 200-day average. None of these signals can predict the outcome with certainty.
