Pre-Market Report – Wednesday 20 May: US markets retreat as bond yields head higher | SPI down 39

US equities extended their decline on Tuesday as a continued selloff in US Treasuries, driven by inflation concerns tied to the war in the Middle East, pressured investor sentiment. The S&P 500 finished 0.7% lower, the Nasdaq closed down 0.8% while The Dow shed more than 300 points, or 0.6%. AI infrastructure companies continued their correction after soaring this month, previously supported by bumper earnings and ambitious guidance. Speculative long positions propelled AI infrastructure stocks higher in the period, prompting a pullback in risk sentiment and a cautious outlook by Seagate to spark a sharp pullback. Seagate sank 10% so far this week. Hyperscalers also fell with Amazon, Tesla, and Meta dropping up to 2% on Tuesday. Meanwhile, Dominion energy sustained its surge from the previous session and NextEra Energy bounced from sharp losses following NextEra's $67 billion acquisition of the former, the largest ever in the power sector.SPI down 39 - Resources under pressure - JHX results - Nvidia in focus—Marcus Today – Daily Market InsightsMarcus Today provides clear, practical commentary for self-directed investors – covering markets, portfolios, education, and decision-making without the noise.If you'd like to go further:Start a free 14-day trial of Marcus Today http://bit.ly/mt-trial-podcastJoin Marcus Today Use code MTPODCAST for 10% off http://bit.ly/mt-join-podcast-offerMT20 – Managed ETF Portfolio A professionally managed portfolio run by Marcus Padley and the team, using ASX-listed ETFs with active market timing. http://bit.ly/mt20-podcastPrinciples – How We Think About Investing A short video series on timing, behaviour, and decision-making.
