Nasdaq Drops 3.5% in One Session: Markets Calm by Monday

The Nasdaq lost 3.5% in a single session on Friday, 30 October 2026. The cause was not macro data or interest rates. Tech earnings reports and growing doubts about the economics of artificial intelligence rattled the market. The S&P 500 closed 1.8% lower the same day.

By Monday morning, 2 November, the panic had faded. Asia recovered part of the losses, with Korea and Hong Kong moving higher, oil retreated, and US Treasury yields held steady. That matters more than the drop itself, because the selloff did not spill over into the debt market.

In short for investors: the market repriced expectations for AI-sector capital spending, and there was no credit event. The behaviour of defensive assets confirms it.

Quick Answer

• Nasdaq -3.5%, S&P 500 -1.8% at the close on Friday, 30 October 2026.
• The trigger was weak tech-sector earnings, including Intel and Reddit; results from Apple and Amazon were digested only after the close.
• Europe fell more gently: Stoxx 600 -0.4%, but dispersion inside the index was huge, with ASML -6.1% and Siemens Energy -6.9% while AstraZeneca and Sanofi rose.
• On Monday, Asia stabilised: gains in Korea and Hong Kong, while weakness persisted in Japan (a collapse in Kioxia).
• US government bonds were unchanged and gold was stable. There was no classic flight to safe-haven assets.
• Oil got cheaper, and volatility declined after Friday's spike.

Key Facts

• The 30 October decline was concentrated in technology: the Nasdaq (-3.5%) fell almost twice as deep as the S&P 500 (-1.8%).
• European banks and tech came under pressure at the same time, yet the broad Stoxx 600 held within -0.4%.
• The dollar traded unevenly, and the Australian dollar weakened ahead of the Reserve Bank of Australia decision.
• In the first week of November 2026 the market awaits final October PMIs, US manufacturing ISM, US jobs data, the RBA decision, US Treasury refunding details, and meetings of the Bank of England and Norges Bank.
• Oil declined as the geopolitical premium in the price eased.
• Thailand's SET index fell for a fourth straight session, closing at 1,518.59, down 26.01 points (1.68%), with 349 decliners against 115 advancers, as reported by finanzen.at on 2 November 2026.

Now to the substance. In the headlines Friday's selloff looked frightening, but mechanically it was fairly routine.

When a market is genuinely afraid, three things happen at once: equities fall, bond yields fall with them, and gold rises. Here only one of the three occurred. US Treasuries stood still and gold did not move. Capital was not fleeing risk altogether. It was leaving one specific overvalued story and looking to reposition within the same risk perimeter. The familiar explanation of a flight to safety does not fit this data, and anyone who sold on Friday evening because of it sold for the wrong reason.

The second observation is about geography. The spread inside the Stoxx 600 tells you more than the index itself: ASML and Siemens Energy lost 6-7% each, while pharma gained. The market was not sold wholesale. Capital moved out of capital-intensive bets on AI infrastructure and into cash flows that are visible today. Semiconductor equipment and power for data centres are the two most sensitive links in the chain of AI capex expectations, and the blow landed on them first.

Third is the speed of recovery. Less than two days passed between Friday's close in New York and Monday's open in Seoul, and in that time the market had already reassessed the situation. That is how corrections inside a rising trend behave, not the start of a reversal.

Our view: the coming weeks will be decided not by earnings but by macro data, namely ISM, PMIs and US employment figures. If jobs data comes in weak, the market will quickly rewrite rate expectations, and tech will find support from the same side the blow came from on Friday. One caveat applies: the reasoning breaks down if weak demand for AI infrastructure is confirmed by order numbers, not just cautious wording in earnings reports. That would mean a revision of the investment cycle itself rather than a repricing of multiples, which is a different story with a different horizon.

For an investor with a foreign-currency portfolio, the practical takeaway is duller than the headlines. A choppy dollar and stable yields mean the cost of money is unchanged for now. One Friday session does not cancel a multi-year decision.

For Phuket real estate, episodes like this show up with a delay and through exchange rates. Stable US yields and a choppy dollar mean borrowing costs and the purchasing power of foreign-currency buyers have not changed yet. The direct effect of the 30 October selloff on Thai property is close to zero, and the demand backdrop remains solid. According to The Phuket News, Phuket luxury property sales rose over 45% year-on-year in H1 2026, with international buyers accounting for 67% of residential purchases (Thai buyers 33%). Bang Tao and Cherng Talay remained among the most sought-after areas. What matters more is what US jobs data and central bank decisions show in November.

FAQ

Why did the Nasdaq fall more than the S&P 500?

The drop was sector-specific. The blow landed on technology after weak earnings, including Intel and Reddit, and the Nasdaq is far more heavily weighted to tech. Hence the gap: -3.5% versus -1.8%.

Is this the start of a market crash?

The data does not support that. US Treasuries stayed stable, gold did not rise, oil got cheaper, and on Monday Korea and Hong Kong already moved higher. Under systemic stress the picture would be the opposite.

What happened to ASML and Siemens Energy?

Both lost 6-7% in the 30 October session (ASML -6.1%, Siemens Energy -6.9%). These companies supply key links of AI infrastructure: chip-making equipment and power solutions for data centres. Doubts about the pace of AI capex hit them directly.

Why didn't gold rise if stocks fell?

Because it was a rotation, not a panic. Investors repositioned within the risk segment rather than leaving risk entirely. For the same reason bond yields did not move either.

Which data will drive markets in November 2026?

Final October PMIs, US manufacturing ISM, US employment statistics, the Reserve Bank of Australia decision, US Treasury refunding details, and meetings of the Bank of England and Norges Bank.

How did currencies react?

The dollar traded without a clear direction. The Australian dollar weakened more than most ahead of the RBA rate decision.

Why did oil get cheaper?

The geopolitical premium in the price compressed a little as tension eased. Oil barely reacted to the equity selloff itself.

Did Thailand's stock market feel it?

Yes. The SET index fell for a fourth straight session to 1,518.59 (-1.68%) on 2 November 2026, with breadth strongly negative at 349 decliners versus 115 advancers.

Should investment decisions change because of one session?

One session without confirmation from the debt market is noise. Watch the macro data of the first week of November and orders in the AI supply chain, not daily index percentages.
