Rio Tinto shares drop
The Rio Tinto Limited (ASX: RIO) share price is missing out of the good times today. Investors have been selling the mining giant's shares after its half-year results fell short of estimates. Rio Tinto reported a 26% decline in underlying EBITDA to US$15,597 million and declared an interim dividend of US$2.76 per share. This compares to estimates of US$16,813 million and US$3.97 per share, respectively.
Tech shares jump
One area of the market that is booming on Thursday is the tech sector. The likes of Block Inc (ASX: SQ2), Megaport Ltd (ASX: MP1), and Zip Co Ltd (ASX: ZIP) are all recording strong gains and helping to drive the S&P ASX All Technology index 1.3% higher today. This follows a very strong night of trade on Wall Street's NASDAQ index, which saw the tech-focused index rise a stunning 4.1%.
Macquarie Q1 update impresses
The Macquarie Group Ltd (ASX: MQG) share price is pushing higher today after investors responded positively to the investment bank's first quarter update. Management advised that favourable trading conditions saw Macquarie's operating groups deliver net profit contributions that were up on the first quarter of FY 2022. The highlight was its annuity-style businesses, which delivered a combined first quarter net profit contribution that was "significantly" up on the prior corresponding period.
Best and worst ASX 200 performers
The best performer on the ASX 200 on Thursday has been the Zip share price with a 16% gain on no news. Its shares have now risen over 200% since the end of June. Going the other way, the worst performer has been the Atlas Arteria Group (ASX: ALX) share price with a 7% decline. This follows news that IFM has walked away from takeover talks.
