Quick Summary

The Australian Securities Exchange (ASX) experienced a brief resurgence last Friday but quickly reverted to bearish trends following strong US economic data and rising costs. Key indicators such as oil prices surged past $107 per barrel, and the yield on the U.S. 10-year Treasury Notes surpassed 5.2%, levels not seen since before the global financial crisis. Amidst this turmoil, Meta’s new AI platform, MUSE, became a focal point for market volatility, driving both euphoria and panic as investors reassessed the potential impact on various industries.

Story summary

Last Friday, the Australian Securities Exchange (ASX) seemed to be recovering from a month of negative trends with a rally that hinted at a potential mini bull market. However, optimism was short-lived as Thursday's unexpected strong US economic data dampened investor spirits. Despite positive indicators like robust manufacturing and service sectors growth along with increased hiring, soaring costs—such as fuel, freight, and labor expenses—cast doubt on the sustainability of this growth. The cost to ship a giant oil tanker has surged to over US$1 million per day, signaling supply chain strain. Meanwhile, Micro-X, Arrow Minerals, and Mamba saw promising developments in their copper exploration efforts, with Micro-X reporting significant intercepts at two locations: 23.1m at 1.1% copper and another shallow but substantial hit of 10m at 1.3% copper. These results, along with new geological models for Mamba, suggest potential rapid advancement in exploration activities.

MICRO-X LIMITED (ASX: MX1) Up 200% (1.8c – 5.4c) Bulls N’ Bears Runner of the Week was portable medical device specialist Micro-X, which rocketed higher on what initially looked like no news at all on its portable scanning technology. asserted
what → rocket → technology
