The context: All three US major indices traded higher overnight, with AI-related names and software stocks continuing to rebound from Monday’s sell-off, as markets brace for Nvidia’s quarterly results.

Nvidia’s earnings are seen as a key test for the tech sector, amid questions over whether recent AI-related sell-offs have been overdone. The chipmaker is expected to report year-on-year earnings growth of 72.2% on revenue of USD66.2 billion, according to analysts polled by Reuters, as demand for AI infrastructure continues. Nvidia shares rose 2.19% ahead of its quarterly report.

Investors also eyed other potential beneficiaries of the AI boom, with Western Digital, Palantir and Applied Materials rising 6.85%, 3.79% and 4.56% respectively. The S&P Software & Services index rebounded from its 23% year-to-date decline, outperformed with a 2.77% gain.

Locally, Atlas Arteria, Karoon Energy, Cleanaway Waste Management, IDP Education, Ramsay Health Care, Qantas Airways and Super Retail Group are among companies to report earnings today.
