Weekly Market Wrap: Intel’s 29% crash turned Big Tech earnings into a stock-market sell-off

Wall Street’s final session of October was no routine pullback. Intel plunged almost 29% after its weak profit outlook, dragging semiconductor shares lower and accelerating a broader exit from the technology stocks that have led the market this year.

The Nasdaq fell 2.9% on Friday, its worst session since June, while the S&P 500 lost 1.8% and the Dow fell 1.1%. That erased earlier gains and left the Nasdaq down 2.0% for the week, the S&P 500 down 0.6% and the Dow 0.9% lower.

Intel’s result was the immediate trigger, but it landed after earnings from Alphabet and Amazon had already unsettled investors. Both companies showed continuing cloud and AI demand, yet their spending plans and cash-flow requirements reinforced concern that the data-centre buildout is becoming harder to finance and justify at current valuations.

The ASX 200 finished the week in much better shape, gaining 1.3% as miners, banks and A-REITs offset the Wall Street technology weakness. That divergence gives Australian traders a clearer split for the week ahead: local cyclicals and rate-sensitive shares face the RBA decision, while US technology stocks need Apple and AMD to restore confidence after Friday’s rout.

Intel’s 29% fall was the week’s defining move. Its weak outlook did not just punish one chipmaker. It put fresh pressure on a semiconductor sector already struggling with concerns over elevated valuations, heavy investment and the timetable for AI demand to convert into profit.

Alphabet and Amazon then made the broader issue harder to dismiss. Both reported strong cloud demand, but investors focused on rising capital expenditure and the cash required to sustain it. Microsoft stood apart because its Azure growth came with substantial free cash flow, giving the market a more credible example of AI investment translating into current financial returns.

Friday’s sell-off changed the tone from an debate over AI spending to a sharper stock-selection market. Investors are rewarding companies that can show revenue growth, margins and cash generation, while punishing businesses whose investment requirements are rising faster than their visible returns.

The ASX 200’s weekly gain came from sectors with a very different set of drivers from Wall Street’s mega-cap technology names.

Materials rose 4.1% as miners recovered, while A-REITs added 3.8%. Banks also attracted interest as the prospect of another RBA rate rise increased. Those sectors gave the local market enough support to overcome continued weakness in consumer staples and selected growth shares.

The RBA meeting is now the main local catalyst. Third-quarter inflation accelerated on higher fuel costs, lifting market expectations that the central bank may raise rates again. Higher rates can support bank margins, but they also increase pressure on mortgage holders, consumers and small businesses.

A rate rise would also put renewed focus on the parts of the ASX that depend on lower borrowing costs, including retailers, property companies and highly valued technology stocks. A hold, particularly if the RBA signals that inflation is still a problem, could produce a similarly mixed response.

For miners, the question is whether the latest rebound can continue. BHP, Rio Tinto and Fortescue remain heavily exposed to Chinese demand, iron ore pricing and the direction of copper. Their gains helped the index this week, but commodity leadership can fade quickly if Chinese data weakens or industrial-metal prices retreat.

Brent’s October gain has supported the energy sector and kept Woodside and Santos on traders’ screens. Supply concerns linked to the Middle East remain the main reason for the elevated oil price.

Higher crude can strengthen earnings expectations for producers, but it does not provide a clean boost to the broader stock market. Fuel costs feed into household budgets, transport expenses and inflation expectations. They can also make it harder for the RBA and Federal Reserve to sound confident that price pressures are easing.

The result is a divided market. Energy producers stand to benefit if Brent remains elevated, while airlines, retailers and rate-sensitive companies face a less favorable cost and policy outlook.

Apple: Can Consumer Demand Outweigh Tech-Sector Doubts?

Apple reports on Monday after a difficult week for the largest US technology names. It is not exposed to the AI spending cycle in the same way as cloud providers, which makes its iPhone demand, services revenue and margin outlook particularly important.

A strong result could offer investors a large-cap technology alternative to the capital-expenditure debate surrounding Alphabet, Amazon and Meta. Weak hardware demand or cautious guidance would add to concern that the technology sector is losing momentum beyond AI infrastructure.

AMD: Is Chip Demand Still Broadening?

AMD’s earnings will provide a direct read on demand for AI chips, data-centre processors and traditional computing markets. Investors will focus on guidance and margins as much as the headline revenue figure.

A strong outlook would help distinguish sustainable chip demand from the recent selling across the sector. A cautious forecast could reinforce the view that investors have become too optimistic about how quickly AI infrastructure spending translates into earnings for suppliers.

Australia 200: Can the RBA Decision Keep the Rally Intact?

The Australia 200 has moved higher on the strength of miners, banks and property stocks, but the RBA decision will test that leadership.

A rate rise could favor banks while pressuring retailers, A-REITs and smaller companies. A hold would likely support rate-sensitive sectors initially, but the statement and forecasts will matter more than the decision alone. Traders will also watch whether higher oil prices force the RBA to keep a hawkish tone into December.

The coming week will test two competing market narratives. US investors want evidence that AI spending will deliver cash returns, while Australian investors need to see whether the RBA can contain inflation without damaging the domestic growth outlook.

Last week separated companies and sectors with clear earnings support from those relying on future expectations. Microsoft’s cloud and cash-flow performance contrasted with the pressure on Alphabet, Amazon and Intel, while miners and banks lifted the ASX despite weakness in US technology shares.
