Tradingkey - During the Asian morning session on May 15, the KOSPI opened lower but trended upward, briefly surpassing 8,000 points to hit a record high, reaching an intraday peak of 8,046.78 points. As of press time, the KOSPI had reversed to a 0.4% decline, trading at 7,949.71. Market analysis suggests three major tailwinds are supporting the upward trajectory of the South Korean stock market: tech giants continue to scale up capital expenditure, significant room remains for the expansion of AI application penetration, and geopolitical factors alongside data sovereignty are driving increased investment from non-US countries. Given the high weighting of AI-related industries among South Korean listed companies, these factors are expected to provide continued support for the market. Furthermore, corporate governance is poised to become a second structural support pillar by 2026, alongside earnings improvement. If companies continue to deliver on share buybacks and cancellations, dividend increases, asset efficiency optimization, and enhanced transparency in information disclosure, the market pricing of the "Korea Discount" is expected to narrow further, driving a valuation recovery for low P/B blue chips from a tactical phase into a sustained trend.
