Semiconductor stocks in the US and Europe climbed on Wednesday, leading a recovery in artificial intelligence-linked stocks after China's low-cost DeepSeek AI tool triggered a punishing selloff this week.
European technology stocks rose, fuelled in part by a near 10 per cent surge in shares of ASML (ASML.AS) after the Dutch-listed company, which makes tools to manufacture computing chips, including those used in AI applications, reported a surprisingly large rise in new bookings.
Peers across the Atlantic such as Applied Materials (AMAT.O) Lam Research (LRCX.O) and KLA Corp (KLAC.O), opens new tab gained between 3.8 per cent and 4.3 per cent in premarket trading.
Shares of Nvidia, which controls 80 per cent of the AI chip market, were marginally higher at $129.77, having closed up 8.9 per cent on Tuesday. The stock was still well below Friday's close of $142.62 and record high of $153.13 on Jan 7.
Nasdaq futures were up 0.4 per cent by 04:50 am ET (0950 GMT), suggesting the cash index could extend Tuesday's 2 per cent rise. An index of European tech stocks (.SX8P) was up nearly 4 per cent, heading for its biggest one-day jump in a year.
Much of that rise was powered by ASML, but shares in chipmakers BE Semiconductor (BESI.AS) and ASM International (ASMI.AS) were also up 5.3 per cent and 6.7 per cent, respectively.
The emergence of DeepSeek's suite of AI tools as possible challengers, not just to incumbents such as OpenAI's ChatGPT, but as a sign development costs may be dropping rapidly, battered AI-linked stocks on Monday, wiping billions in market value off Nvidia, as well as other technology companies.
Nvidia slumped 17 per cent on Monday, which cost the company almost $600 billion in market value - the largest single-day drop in market capitalisation for any company on record.
"Nvidia is not a lone wolf. At the end of the day, Nvidia carries with it more than $10 trillion of market cap of affiliated companies, whether they're doing nuclear, industrial equipment, suppliers to Nvidia. So it's a galaxy, not just the one company," Jacques-Aurélien Marcireau, co-head of equities at Edmond de Rothschild Asset Management, said.
DeepSeek launched a free AI assistant last week that quickly overtook OpenAI's ChatGPT on Apple's App Store in the United States and the cost and performance of the company's AI tools seemed to upend the belief in the industry that China was years behind its US rivals in the AI race.
By Wednesday, there was a greater sense of calm across markets, as investors focused on upcoming earnings from several of the so-called Magnificent Seven US megacaps, which count Nvidia, Apple (AAPL.O) and Microsoft (MSFT.O), among their ranks.
"While questions remain unanswered, the market is voting that the innovation that DeepSeek could bring to the ecosystem will unlikely impact the AI capex cycle and could even lead to new channel of demand for GPUs (graphics processing units)," Pepperstone strategist Chris Weston said.
Separately, Microsoft and OpenAI - run by Sam Altman - are probing if data output from the ChatGPT maker's technology was improperly used by a group linked to DeepSeek, Bloomberg News reported on Tuesday.
