[Analysis] Semiconductor Rally Continues: Foreign Buying and Index Rise

Semiconductor Rally Continues: Strong Upward Trend Led by Large-Cap Stocks

As of May 25, 2026, the Korean stock market is witnessing a clear continuation of the semiconductor rally. Driven by strong foreign buying centered on large-cap semiconductor stocks such as Samsung Electronics and SK Hynix, the overall market index is experiencing a solid upward trend. Coupled with the expanding global demand for AI infrastructure, expectations for an industry turnaround are growing, translating positive assessments of Korean semiconductor fundamentals into substantial capital inflows. Rather than fluctuating index numbers, this definitive upward trajectory is stimulating overall investor sentiment and providing robust downside support.

Core Drivers Behind Foreign Capital Inflows

The primary catalyst for this current market phase is undoubtedly the large-scale influx of foreign capital. With a broad earnings turnaround confirmed in the global semiconductor sector, movements to increase semiconductor weighting within portfolios are being captured.

• Upward Revisions in Earnings Forecasts: Continuous upward revisions in the profit forecasts of major semiconductor companies have enhanced their investment attractiveness relative to corporate value.

Structural Growth of the AI Ecosystem: Surging demand, such as the expansion of global AI data centers, directly translates into demand for High Bandwidth Memory (HBM) and general memory semiconductors, highlighting structural growth.

Global Capital Rebalancing: Amidst a tech-driven rally, there is a visible trend of capital rotating into Korean large-cap semiconductor stocks, which offer relative valuation merits.

Future Index Outlook and Investment Strategy

While market experts highly evaluate the possibility of the semiconductor rally continuing, they also point out that a temporary breather may accompany the short-term surge. Whether foreign capital inflows are sustained will be the key variable determining further upside for the KOSPI index. Investors must prepare for potential short-term profit-taking while closely monitoring macroeconomic variables, including shifts in global AI industry trends, the direction of major monetary policies, and KRW/USD exchange rate volatility. It is a critical time to maintain a long-term perspective on structural growth stocks while concurrently implementing risk management strategies to enhance portfolio stability.
