Japanese and South Korean Stocks Rally, Led by Chip Sector Surge

On Wednesday, October 28th, a wave of buying swept through two of Asia's major equity markets, Japan and South Korea. The semiconductor sector stood at the forefront of this rally, with chip stocks powering the major indices significantly higher.

Japan: Nikkei 225 Breaks Through Resistance

Japan's Nikkei 225 index closed the session up 685.82 points, a gain of 1.08%, finishing at 63,954.19. This move pushed the index past a key technical and psychological level. Shares of companies in the chip-making space were among the top performers, with memory chip specialist Kioxia soaring nearly 14%.

South Korea: KOSPI Reclaims 6000 After 10 Sessions

The rebound was even more pronounced in South Korea. The benchmark KOSPI index jumped 374.1 points, or 6.63%, to close at 6,012.44. This marked a significant milestone, as the index climbed back above the 6000-point threshold for the first time in ten trading days.

The surge in Seoul was driven by its technology heavyweights. Shares of SK Hynix, a leading memory chipmaker, leaped almost 11%. Samsung Electronics, the conglomerate giant in electronics and semiconductors, saw its stock rise approximately 9%. The robust performance of these index titans provided a major boost to the overall market.

Market Drivers: What Fueled the Rebound

The synchronized upswing in Tokyo and Seoul points to several underlying factors that may be shifting investor sentiment:

  • Improved Sector Outlook: Expectations are growing that the global semiconductor cycle may be bottoming, with signs of demand recovery boosting confidence in chip stocks.
  • Technical Bounce: Markets had been oversold after a period of decline, creating conditions ripe for a rebound as valuations became more attractive.
  • Heavyweight Influence: The outsized impact of giants like Samsung, SK Hynix, and Kioxia on their respective indices means their gains have a magnified effect on the broader market.

While a single day's rally doesn't necessarily confirm a sustained trend reversal, the recovery of the 6000-point level is a psychologically important win for the South Korean market, potentially helping to stabilize sentiment and lay groundwork for further gains.
