Highlights

  • The ASX 200 opened lower after weakness on Wall Street, led by declines in technology shares.
  • Oil prices fell back to levels seen before the recent US-Iran conflict, pressuring the energy sector.
  • Gold miners showed relative resilience while broader market sentiment remained cautious.

Australian shares opened lower on Thursday as global market sentiment softened following a weaker overnight session in the United States. Technology stocks led declines on Wall Street after semiconductor shares retreated, while falling crude oil prices weighed on energy producers. Investors also continued assessing central bank policy signals and upcoming economic data.

Wall Street sets a weaker tone

US markets finished mostly lower overnight as technology stocks came under renewed pressure.

The Nasdaq declined after a broad sell-off across semiconductor companies, while the S&P 500 also ended in negative territory. The Dow Jones Industrial Average was comparatively resilient but finished little changed.

Chipmakers remained under pressure as several technology companies extended recent losses, reducing appetite for higher-growth sectors.

Oil prices retreat sharply

Crude oil prices fell further after easing geopolitical concerns surrounding the Middle East.

With supply disruption fears moderating following developments involving the United States and Iran, Brent and West Texas Intermediate prices slipped back toward levels seen before the conflict escalated.

Lower oil prices weighed on Australian energy producers during early trade as markets reassessed near-term earnings expectations across the sector.

ASX sectors under pressure

Most sectors traded lower during the opening session.

Consumer discretionary shares weakened after a strong rally over recent weeks, while materials stocks extended recent declines amid softer commodity prices.

Energy shares also retreated alongside weaker crude prices.

Gold-related companies provided one of the few areas of relative strength as bullion prices remained supported by cautious global sentiment.

Gold stocks attract attention

Several gold producers outperformed the broader market during morning trading.

The sector continued benefiting from demand for defensive assets as uncertainty surrounding interest rates and global economic growth remained in focus.

Gold prices also found support from lower bond yields and ongoing expectations that central banks could eventually ease policy once inflation moderates further.

Company news in focus

Among individual companies drawing attention:

  • Northern Star Resources (ASX:NST) reported preliminary FY2026 gold sales above its revised guidance while maintaining progress on expansion projects.
  • Electro Optic Systems (ASX:EOS) gained after announcing new defence contracts in the Middle East.
  • Intelligent Monitoring Group (ASX:IMB) unveiled a major acquisition of ADT's UK residential security business.
  • Kelsian Group (ASX:KLS) secured a long-term Auckland ferry contract and announced the acquisition of Belaire Ferries.
  • Iluka Resources (ASX:ILU) entered an 18-year rare earth concentrate supply agreement supporting its Eneabba refinery.

Energy sector faces renewed pressure

The decline in crude oil prices placed additional pressure on Australian energy stocks.

Investors monitored whether improving supply conditions and reduced geopolitical risk could limit near-term support for oil prices.

Attention also remained on longer-term global demand trends and production discipline among major oil producers.

Global macro themes remain important

Markets continue watching several macroeconomic developments, including:

  • US employment data due later this week.
  • Central bank commentary regarding inflation.
  • Global technology earnings expectations.
  • Commodity price movements.
  • Chinese economic activity and manufacturing data.

These factors are expected to influence risk sentiment across Australian equities over coming sessions.

Market outlook

The weaker start reflects cautious global sentiment rather than broad-based domestic weakness. While technology and energy shares faced selling pressure, defensive sectors including gold continued attracting interest. Investors are likely to remain focused on overseas economic data, commodity markets and corporate updates as the new financial year begins.
