Closing Bell 28th January: Tech and Data Centres fall on DeepSeek fears. ASX rises led by financials

Technology, electricity, and data centre companies faced significant sell-offs on Tuesday amid investor concerns that China’s advancements in cost-effective AI could pressure earnings for firms like Nvidia and reduce demand for energy-intensive data centres.

The S&P/ASX 200 was higher in early afternoon trading, up just 2.1 points to 8411, reversing earlier gains. Overnight, Wall Street tumbled, with the Nasdaq dropping 3% as traders feared the Chinese start-up DeepSeek’s AI could disrupt the US tech sector. Nvidia shares plunged 16.7%, while Constellation Energy dropped over 20%.
