Hang Seng closes at 3-year highs as investors turn their focus to Nvidia

European futures are set to open higher on Wednesday, as investors look ahead to results from tech giant Nvidia after markets close across the Atlantic. In Asia, China's Hang Seng index closed at a nearly three-year high.

Hong Kong indexes rose, extending a recovery that began last month, driven by a belief that technological advances in China could help revive the country's economy. Hong Kong's Hang Seng Index closed in the green, up 3.65%. The Shanghai Composite also rose more than 1%.

Hong Kong indexes were the standout asset in Asian trading after DeepSeek reopened access to its main programming interface after a nearly three-week suspension, resuming a service crucial to wider adoption of an artificial intelligence model that has proved remarkably popular since its introduction last month.

In Japan, the Nikkei closed the session down 0.25%. The Topix also did not escape losses and closed down 0.30%.

The resilience of tech companies will be tested when Nvidia reports results after the close of major US indexes.

“Nvidia’s numbers could very well be a make-or-break event for the market, at least in the short term,” Tim Waterer, chief market analyst at KCM Trade in Sydney, told Bloomberg. He added that “what could really drive sentiment one way or the other could come down to whether the company’s outlook remains as bullish as it has been.”

Also focusing attention on the Old Continent is news that Ukraine has reached an agreement with the US for the exploitation of its natural resources, a measure that could ease the recent tension between Trump and Ukraine and advance his Administration's objective of a ceasefire with Russia.

France hopes the US will provide support to European troops to help keep the peace in Ukraine once a ceasefire is agreed between Ukraine and Russia.
