The KOSPI opened lower on Friday, slipping about 1% [5] to approximately 8,828 points [4] following a volatile trading period in Seoul.
This downturn marks a sharp reversal for South Korean markets, which had been riding a wave of optimism regarding semiconductor demand. The sudden shift highlights the sensitivity of the KOSPI to global tech giants and the volatile cost of raw components.
The decline follows a significant surge on Thursday, during which the KOSPI rose more than five percent [1]. That rally briefly pushed the index above 9,000 points [2] before it closed the day at 8,930 points [3]. The momentum from the previous session had been largely fueled by record earnings reported by Micron.
However, the market sentiment shifted after Apple announced it would raise product prices. The company said rising memory-chip costs were the primary driver for the price increases [1]. This announcement unsettled tech and memory-related stocks, erasing some of the gains from the previous day's rally.
The downward trend extended to other sectors of the market. The KOSDAQ also opened lower, falling 0.9% [6] to reach 879 points [7].
Investors are now monitoring whether the price pressures cited by Apple will signal a broader trend in the semiconductor supply chain. While Micron's earnings provided a temporary boost, the actual cost of components is creating a friction point for consumer electronics pricing.

The rapid swing from a 5% rally to a 1% decline demonstrates the KOSPI's heavy reliance on the semiconductor ecosystem. While strong earnings from firms like Micron suggest high demand, Apple's decision to pass rising chip costs to consumers indicates that inflationary pressures in the supply chain may outweigh the benefits of high volume, creating a ceiling for tech stock valuations.
