International investors divested more than 10 trillion South Korean won — approximately $6.6 billion — in Samsung Electronics and SK Hynix stock during the previous week. This divestment pattern has now continued unbroken across 12 consecutive trading days.

According to data released by the Korea Exchange and Yonhap Infomax, the figures represent the trading week commencing May 18.
During this timeframe, international market participants sold a net total of 5.33 trillion won in SK Hynix shares alongside 5.26 trillion won in Samsung Electronics holdings.
Combined, these two technology companies comprised 73 percent of the entire foreign divestment activity across the Korean equity market last week. Aggregate foreign selling in Korean stocks totaled 14.45 trillion won during the same period.
The divestment wave began on May 7, marking the point when foreign capital turned to net selling positions. Across the entire 12-session timeframe, international investors disposed of a net 19.53 trillion won in SK Hynix and 18.87 trillion won in Samsung Electronics.
These two companies singularly represented 82.9 percent of the cumulative 46.34 trillion won in foreign divestment throughout that span.
Additional companies experiencing foreign selling pressure included Hyundai Mobis, Hyundai Motor, LG Electronics, and Samsung Electro-Mechanics.
Capital Reallocation Destinations
While exiting semiconductor positions, international investors channeled resources into alternative segments of the Korean equity market.
Within the primary Kospi exchange, they acquired a net 370 billion won of Doosan Robotics shares and 148.9 billion won of Samsung SDI shares. Samsung SDI specializes in battery technology and energy storage solutions.
On the Kosdaq secondary exchange, foreign participants registered net purchases totaling 1.29 trillion won.
Fadu, a fabless semiconductor company specializing in storage systems for artificial intelligence data centers, attracted foreign net investment of 155.6 billion won. Seojin System, an ESS and telecommunications equipment manufacturer, received 128 billion won in international purchases.
Market Experts Identify Portfolio Rebalancing Strategy
Financial analysts characterize the divestment as a strategic rebalancing initiative rather than diminished confidence in the semiconductor industry.
Semiconductor equities had experienced significant price appreciation during the period preceding the selloff wave. Consequently, these positions expanded beyond target allocations within foreign investment portfolios.
“Foreign investors may have responded with selling as the share of Korean semiconductor stocks in their portfolios increased sharply due to steep price gains,” said Kang Jin-hyuk, an analyst at Shinhan Securities.
He further noted that investors appear to be reallocating capital toward equities demonstrating earnings growth potential while maintaining comparatively modest valuations.
The international robotics and ESS sectors are viewed as expansion opportunities, propelled by demand from physical AI applications and artificial intelligence data center infrastructure.
As of May 22, the Kospi index settled at 2,847.71 points, registering a 0.41 percent daily increase.
