TradingKey - Recently, the South Korean stock market has repeatedly hit record highs. At the market open on May 15, the KOSPI Index briefly broke through the 8,000-point psychological level before staging a sharp intraday plunge, with losses exceeding 7% at one point. It closed down 6.12%, signaling collective profit-taking as investors locked in gains at key resistance levels.

TradingKey - On May 14, Eastern Time, the three major U.S. stock indices closed higher across the board, with the Nasdaq and S&P 500 both hitting record highs. The Dow Jones Industrial Average closed above the 50,000 mark for the first time in three months. On the same day, Kevin Warsh officially succeeded Jerome Powell as Chair of the Federal Reserve, ushering in the Fed's "Warsh Era."

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.
