South Korea's Kospi led gains across most Asian markets on Friday as a record-breaking US share sale by chip titan SK hynix breathed fresh life into the tech sector after weeks of selling.
In Seoul, the Kospi closed up 2.5% to 7,475.94 points; Tokyo - Nikkei 225 ended up 1.2% to 68,557.73 points; Hong Kong - Hang Seng Index closed up 0.6% to 24,175.12 points and Shanghai - Composite ended down 1.0% to 3,996.16 points yesterday.
The breathtaking $26.5bn listing by SK provided some much-needed affirmation to investors that the AI boom remains on course, despite lingering worries about extended valuations and eye-watering capital spending.
The news came as attention turns to the upcoming earnings season, with traders looking to company outlooks for the industry and investment plans amid expectations that interest rates will be kept elevated for the time being.
SK hynix set a price of $149 for each American depositary share (ADS) -- slightly more than its Seoul closing price on Thursday -- ahead of its debut on the Nasdaq on Friday.
That meant it had raised $26.5bn, the most for a US listing by a foreign firm.
The company, a supplier of advanced memory chips to industry behemoth Nvidia, has seen profits skyrocket thanks to the global race to build artificial intelligence data centres.
Its Seoul-listed shares had ballooned almost 700% in the 12 months to its peak on June 23, before it got caught up in a global tech rout fuelled by fears of overheated valuations and questions about when huge investments will reap returns.
SK hynix, along with Samsung and Micron, is a heavyweight in the global market for the advanced components known as high-bandwidth memory (HBM), used in AI servers alongside other data-crunching semiconductors.
Stephen Innes at SPI Asset Management said the fact the share sale was more than seven times oversubscribed "tells you all you need to know about the current temperature of the market".
"Investors are still desperate for anything bolted to AI infrastructure, especially if it sits close to the high-bandwidth memory bottleneck."
Seoul's Kospi jumped more than 5% at one point on Friday before paring the gains, though SK hynix dipped, having added around 5% on Thursday.
Samsung was more than two percent higher.
Tokyo rose more than 1%, with tech investment giant SoftBank piling on more than 10%, while Tokyo Electron and Advantest were each more than two percent up.
Hong Kong, Mumbai, Singapore, Sydney, Bangkok and Manila joined the advances, though Shanghai edged down.
London, Paris and Frankfurt rose.
The mood on oil trading floors was also a little less tense than earlier in the week as investors became less concerned that the recent US-Iran flare-up over the Strait of Hormuz would reignite their war.
Both main crude contracts fell Friday, having dropped around two percent the day before, with analysts pointing out that more oil is produced outside the Gulf region, tempering the impact of disruptions.
The fall in prices on Thursday "suggests investors continue to view the latest escalation as a temporary setback rather than the start of a prolonged conflict", said City Index's Fiona Cincotta.
"Oil prices are pulling back after Wednesday's sharp rally, indicating that markets still expect diplomacy to ultimately prevail and that any disruption to global energy supplies is likely to be limited."
