US equity markets rebounded sharply as technology stocks rallied following a wave of selling in recent sessions - Dow jumped +1,207-points or +2.47% to a record closing high of 50,115.67, the first time the 30-stock index has climbed above the 50,000 mark. Nvidia Corp +7.87%, with Chief Executive Officer (CEO) Jensen Huang saying in a televised interview with CNBC that demand has been "going through the roof" as cloud heavyweights lead what he believes could become the “largest infrastructure buildout in human history.” Caterpillar Inc +7.07%. However, Amazon.com Inc fell -5.55% after the company forecast a more than 50% jump in capital expenditures this year as part of its fourth quarter result released after the close of the previous session, intensifying the AI-driven spending spree already underway among its "Magnificent Seven" mega-capitalisation peers.
