- ASX slides as tech and miners stumble
- China’s Simandou move rattles iron ore giants
- Rare earths and rate hopes crushed in one morning
The ASX was down around 0.7% by lunchtime in the east on Wednesday, extending yesterday’s 0.9% loss.
Overnight in New York, the S&P 500 lost 1%, and the Nasdaq copped a 1.7% slap as tech finally remembered that valuations can’t levitate forever.
Nvidia also sagged 3% after Michael Burry (yes, the Big Short guy) revealed he’s shorting it. The most renowned time he successfully called a bubble, the world nearly ended (GFC 2008); this time, maybe just the Magnificent 7 portfolio will.

Back home this morning, the ASX tech sector led the sell-off as Aussie traders took their cues from Wall Street.
Mining was the second weakest sector, down about 2.5% as iron ore futures slid 1.5%.
China’s backing for Guinea’s Simandou project, apparently the world’s largest untapped iron ore deposit, has spooked the big boys.
Rare earth stocks also took a beating this morning.
Lynas (ASX:LYC) slid 5% and Arafura Rare Earths (ASX:ARU) took a stinging 11% hit as retail punters started bailing out now that US-China trade tensions look calmer, at least for this week.

In other large cap news, Goodman Group (ASX:GMG) slipped 2.5% despite reaffirming its FY26 earnings growth target of 9%.
The company’s riding the data-centre wave, with $12.4 billion of work in progress and 68% of that tied to digital infrastructure.
Goodman says demand’s hot, and in fairness, AI data storage is the new beachfront property.
Bluescope Steel (ASX:BSL) fell 2% after announcing a new CEO – Tania Archibald takes the helm from Mark Vassella.
Medibank Private (ASX:MPL) was one of the few bright spots, up 1% after agreeing to buy Better Medical, a network of 61 GP clinics, for $159 million.
And … it looks like the Kiwis are doing it tough.
Data today shows NZ’s jobless rate climbed to 5.3%, its highest since 2016. No wonder almost 50,000 have moved to Australia in the past year.

Mont Royal Resources (ASX:MRZ) came back to the boards with a bang this morning, rocketing more than 600% after completing its merger with TSX-V listed Commerce Resources.
The deal creates a new Canadian-focused critical minerals developer built around the Ashram Rare Earth and Fluorspar Deposit in Québec, one of North America’s largest rare earth assets.
Ashram already boasts a Tier-1 resource (73.2Mt at 1.89% TREO Indicated and 131.1Mt at 1.91% TREO Inferred), with over A$50 million spent historically on development.
With a fresh $10 million raise and a board led by ex-Primero Cameron Henry and ex-Meteoric Nick Holthouse, the company is now starting an updated Preliminary Economic Assessment to streamline development.
TMK Energy (ASX:TMK) notched up another record month at its Gurvantes XXXV coal seam gas project, with October gas output jumping 25% from September and more than doubling since August.
Average production hit about 395 cubic metres a day in October and has already climbed to around 470 cubic metres a day so far in November.
Great Dirt Resources (ASX:GR8) has confirmed high-grade manganese at its Basin and Neranghi projects in NSW, with rock chip assays returning up to 51.8% manganese oxide.
Sampling of historic workings has mapped large outcrops and boulders, while results at the Basin (Copper Hill) area suggest mineralisation is aligned with host rock structures, hinting at a potential primary stratiform manganese system.
