International Factors Shape Sentiment
Investors saw mixed signals from overseas. US stocks advanced with the S&P 500 up 1.23% to 6,875.16, and the Nasdaq up 1.86% to 23,637.46, bolstered by chipmakers and strong earnings. China’s CSI index rose 1.19%, and Japan’s Nikkei climbed 2.46% on trade optimism. The US and China reached preliminary agreements on technology exports, shipping levies, and fentanyl regulation, improving outlook for Australian exporters.
ASX Performance Overview
The ASX 200 fell 0.4% to 9,018 in early trade. The market erased 40% of its prior gains, reflecting cautious sentiment ahead of key domestic events. The All Ordinaries retreated to 9,351.9 after Monday’s gain of 0.37%. Eight of eleven sectors held positive ground earlier in the week, but volatility persisted, especially in healthcare and rare earths stocks.
Notable Movements: CSL and WiseTech
CSL (ASX: CSL) shares dropped over 14% after announcing delays in spinning off its vaccine division due to heightened volatility in the US influenza vaccine market. CSL revised revenue forecasts down for its Seqirus segment after unexpected declines in US vaccination rates, confirming the demerger will proceed only in favourable conditions. Monday’s announcement triggered sector-wide caution.
WiseTech Global (ASX: WTC) tumbled 16% to $71.50 after a surprise investigation by ASIC and the Australian Federal Police. The search warrant targeted alleged trading activity by founder Richard White and employees from late 2024 to early 2025. WiseTech stated, “So far as WiseTech is aware, no charges have been laid against any person and there are no allegations against the Company itself.” The firm committed to cooperate fully with authorities.

Together, CSL and WiseTech erased nearly $20 billion from market capitalisation, heavily weighing on the benchmark index.
Rare Earths Miners Slide
Despite optimism about normalising US–China rare earths trade, local rare earths stocks declined sharply. Iluka Resources (ASX: ILU) fell 6.87%, and Arafura Rare Earths (ASX: ARU) dropped nearly 10% amid expectations that resuming cross-border trade will temper demand for local minerals.
Other Key Stocks and Updates
Notable performers in Monday’s trade included Block (up 1.8%), Santos (up 1.5%), Brambles (up 1.5%), and Aristocrat Leisure Limited (up 1.4%). Liontown Resources remained in focus ahead of its quarterly update, with Macquarie forecasting spodumene production 4% above market expectations for 1QFY26, anticipating shipments weighted in the second half.
Institutional Momentum
Institutional investors continued adapting portfolios in response to global and local developments. Private companies held 28% in TPG Telecom (ASX: TPG), influencing corporate strategy as market volatility persists.
Interest Rates and Monetary Policy
Investors closely watched the Reserve Bank’s policy stance. Three rate cuts earlier in the year injected optimism, but persistent price pressures in recent inflation data could prompt the central bank to maintain current policy settings next week. The market’s attention shifted to upcoming quarterly inflation figures, guiding expectations for monetary policy and risk assets.
Tony Sycamore, IG markets analyst, commented, “Not entirely the most convincing performance I’ve seen given the news we have out there, which does obviously provide a further backdrop for risk assets and potentially ease concerns around a slowdown into year end. We need to get some of the unknowns out of the way, specifically with regards to the inflation data here in Australia”.

Earnings Season and Market Outlook
Earnings season intensified, with 180 S&P 500 companies reporting results overseas — a trend reflected locally as annual meetings and quarterly results from major ASX companies shape forecasts. FactSet data indicated blended net profit margins for the S&P 500 at 12.8%, above last year’s average, though analysts warned of high expectations and potential volatility around artificial intelligence-related spending.
Conclusion: Investor Caution Prevails
At market open, Australian stocks reflected cautious sentiment. International gains set an optimistic tone, but local impacts from the CSL and WiseTech developments dominated investor vigilance. Focus remains on approaching inflation data and earnings releases to guide future moves in Australian equities. Institutional and retail participants continue adjusting strategies amid shifting domestic and global landscapes, with macroeconomic trends and regulatory investigations shaping outcomes at the ASX.
