ASX 200 Surrenders Half Its Weekly Gains as All Ords Lags

Aussie markets retreated sharply on Friday, with the ASX 200 erasing half its weekly gains as a brutal selloff in technology stocks and weakness across materials and industrial sectors outweighed resilience in energy and financial names. The All Ords fell 1.54% on the day, giving back almost two thirds of it’s respective increase, leaving behind gains of 0.8% on the week.

Shifting back to the ASX 200, the bluechip index closed at 8,917.60, down 1.39% for the session but clinging to a 1.21% gain for the week. The benchmark index failed to hold the psychologically significant 9,000 level, retreating from earlier weekly highs as sector-specific pressures intensified into the weekend close, yet a close above 8,900 remains a positive.

At a sector level, the Information Technology Index (XIJ) bore the brunt of selling pressure, plunging 5.06% to close at 1,634 for its lowest level in more than two years. The Materials Index shed 2.02%, while both the Industrials (XNJ) and Financials (XFJ) indices declined 0.84%, demonstrating the breadth of Friday’s weakness across the market.

The Days Movers – A Lot Of Red

The technology sector’s collapse reflected global concerns over artificial intelligence disruptions and escalating memory-chip prices that threaten profitability margins. WiseTech Global (WTC) tumbled 10.41% to $42.62, while high-flying healthcare technology play Pro Medicus (PME) surrendered 8.36% to close at $118.22. The selloff extended to technology-adjacent names, with Life360 (360) dropping 10.09% to $22.02 and fintech player Zip Co (ZIP) declining 8.46% to $2.38.

Medical device manufacturer Cochlear (COH) suffered the day’s third-worst performance, plummeting 18.9% to $199.22 after delivering half-year results that disappointed markets despite the company’s strong market position in hearing implants. The result highlighted how elevated valuations in the healthcare sector have left little room for execution shortfalls.

Retail furniture specialist Nick Scali (NCK) defied logic, crashing 22.32% to $18.48 despite reporting a robust 36.4% increase in half-year profit to $40.9 million. The counterintuitive move suggests markets had priced in even stronger results or harboured concerns about forward guidance in a challenging consumer environment.

Defence contractor Austal (ASB) recorded the session’s steepest decline, collapsing 22.82% to $4.87 following an accounting irregularity.

Leading The Index

Against the backdrop of widespread selling, energy stocks delivered the session’s standout performances. Origin Energy (ORG) surged 5.04% to $12.08 following momentum from half-year earnings that exceeded expectations, with the company upgrading its full-year energy markets guidance. Rival AGL Energy (AGL) advanced 2.56% to $10.42.

Financial services group AMP (AMP) rebounded sharply, gaining 8.98% to $1.395 as bargain hunters emerged following the stock’s sharp decline earlier in the week after underwhelming earnings. Fund manager GQG Partners (GQG) climbed 7.76% to $1.735.

Data centre operator NextDC (NXT) bucked the broader technology selloff, rising 3.7% to $14.02 on continued demand for digital infrastructure services, demonstrating that not all technology subsectors faced the same headwinds.

Heading In To Next Week

This week’s trading reflected competing forces shaping market sentiment. Strong earnings reports from major banks including ANZ Group provided support early in the week, contributing to the positive weekly result. However, global concerns over technology valuations, AI disruption risks, and commodity price weakness weighed heavily as the week progressed.

While technology faces questions about sustainability of recent valuations amid rising input costs, traditional energy companies are benefiting from tight supply-demand dynamics and elevated wholesale prices.

The Materials Index decline of 2.02% reflected a pullback in commodities, with weakness in iron ore and base metals prices pressuring major miners. This commodity weakness, combined with the technology rout, created a challenging environment for the broader index despite pockets of strength.

The ASX 200’s failure to hold 9,000 points may invite technical selling in coming sessions, though the index’s ability to post a weekly gain despite Friday’s retreat demonstrates underlying market resilience. The divergence between sectors suggests markets are making discriminating judgments about valuations and earnings quality rather than engaging in indiscriminate selling.

The coming week will test whether Friday’s selloff represents healthy profit-taking after a positive week or signals deeper concerns about market fundamentals. With technology stocks at two-year lows and select energy names rallying, sector rotation appears to be accelerating, creating both risks and opportunities for active portfolio managers.
