According to The Korea Herald, HKET and RTHK, Asian equities closed broadly higher on Thursday, led by a powerful rally in South Korea after SK hynix unveiled a record share buyback, while easing U.S. Treasury yields lifted risk appetite across the region.

Tokyo's Nikkei 225 rebounded from a two-day slide, closing at 66,216, up 890 points or 1.36%. Chip-related names were mixed: Sony added 2.39% and Advantest gained 0.97%, while Tokyo Electron slipped 1.17%.

Seoul's KOSPI was the standout, surging 5.89% to close at 6,852.58, with the secondary Kosdaq up 1.99% at 840.89. The advance was driven by SK hynix, which jumped 12.73% to 1,691,000 won after announcing a 40 trillion won ($28.7 billion) share buyback and cancellation covering about 3.3% of its stock — the largest treasury-share cancellation by a listed Korean company. Samsung Electronics climbed 9.49% to 271,000 won on expectations it could step up shareholder returns. Foreign investors bought a net 1.7 trillion won of shares.

Everest Medicines surged more than 40% and Bank of East Asia rose over 5% to a high, while Kuaishou tumbled 11% to a fresh low after results and Alibaba added more than 1% ahead of its earnings.

Taiwan's TAIEX rose 214.39 points, or 0.48%, to close at 44,933.74 on thinner volume. TSMC gained 1.06% to close at NT$2,375, while MediaTek fell 3.77%.

In mainland China, the Shanghai Composite recovered from the prior session's losses to close up 9 points, or 0.24%, at 3,903, the Shenzhen Component rose 0.59% to 13,972 and the ChiNext Index added 0.64% to 3,495.
