South Korea's KOSPI index jumped more than 5% on Thursday, briefly reclaiming the 9,000-point level as investors rushed into semiconductor stocks.
The broad market rally was anchored by a wave of buying in the technology sector, lifting the benchmark to its highest level in months.
The surge was ignited by positive earnings from US memory chip giant Micron, which provided a catalyst for the wider semiconductor complex.
Traders in Seoul interpreted the results as a sign of sustained demand in the memory market, prompting aggressive positioning in local chipmakers and related technology names.
The rally came against a backdrop of easing geopolitical risks in the energy sector, with Brent crude plunging to pre-war lows as shipping resumed through the Strait of Hormuz.
The combination of lower energy costs and renewed optimism in the tech sector helped fuel the broad-based advance in Korean equities.
