The biggest gains, however, came from chipmakers and companies tied to the AI hardware supply chain.

SK Hynix jumped to eighth place after a 282% increase in market capitalisation, which GlobalData linked to strong demand for high-bandwidth memory (HBM) used in AI data centres and order backlogs extending into 2026.

Samsung Electronics rose to third, posting a 126% gain following a late-2024 HBM3E production breakthrough.

Other notable movers included Foxconn Industrial Internet, up 201% to 18th, Advantest, up 114% to 46th, and Tokyo Electron, which entered the top 40 after a 42% rise.
