Global institutional investors are reducing exposure to Asian semiconductor stocks SK Hynix, Samsung Electronics, and TSMC after their combined market capitalizations doubled to approximately $1 trillion each over a six-month period, according to Financial Times reporting. The concentration has triggered risk concerns as the three companies now represent roughly 29% of the MSCI Emerging Markets Index — nearly three times the weight of all Indian stocks combined and exceeding the combined market caps of Brazil and South Africa with SK Hynix alone. Asset managers including BlackRock and Fidelity International cited the index concentration and leveraged positioning in Korean semiconductor stocks as warning signals, with Caroline Shaw of Fidelity describing the situation as a "boundary line" prompting questions about overheating.
Three Stocks Command 29% of MSCI Emerging Markets Index
The market capitalizations of SK Hynix, Samsung Electronics, and TSMC each reached approximately $1 trillion (1,508 trillion won) after nearly doubling in the most recent six-month period. The three stocks' combined weighting in the MSCI Emerging Markets Index stands at roughly 29%, approaching three times the weight of all Indian equities combined. SK Hynix's market cap alone surpasses the combined total of Brazil and South Africa. The concentration has created burden for index-tracking investors, according to fund managers interviewed by Financial Times.
BlackRock and Fidelity Reduce Semiconductor Exposure
Caroline Shaw, multi-asset portfolio manager at Fidelity International, identified the index concentration and spread of leveraged bets on Korean semiconductor stocks as a "boundary line" that "makes us question whether this is overheating." She stated the firm is reducing growth stock weightings and examining companies overlooked within emerging markets. Wei Li, chief investment strategist at BlackRock Investment Institute, said the firm is "willing to realize profits at this point" due to volatility in some semiconductor and memory stocks, and is reducing overweight positions in emerging market equities. Active funds face regulatory constraints typically limiting single-stock holdings to 10% of assets.
Foreign Investors Net Sold $100 Billion in Korean Stocks
Foreign investors net sold $100 billion (150.78 trillion won) worth of Korean stocks this year, pressuring the won's value. The Korean stock market declined over 20% from its peak last month. The outflows occurred despite SK Hynix raising $26.5 billion (39.96 trillion won) through its Nasdaq listing last week and both SK Hynix and Samsung Electronics posting record first-quarter earnings.
Q1 Profits Exceeded $50 Billion Despite Market Decline
Samsung Electronics and SK Hynix recorded combined first-quarter net profits exceeding $50 billion (75.39 trillion won), more than five times the figure from the same period last year (under $10 billion). Sunil Tirumalai, head of emerging market equity strategy at UBS, stated the companies "have effectively become oligopolistic operators" and noted that "monopolistic businesses always generate fantastic profits and make very good stocks."
Intel Foundry Revival and Chinese Memory Makers Pose Competition
Kieran Pun, Asia equity investment director at abrdn, attributed TSMC's underperformance relative to the other two stocks this year to Intel's foundry business revival. On the memory side, China's CXMT (Changxin Memory Technologies) and YMTC (Yangtze Memory Technologies), both preparing for listings within the year, are identified as the largest threats. Christopher Wood, global head of equity strategy at Jefferies, characterized the two companies' listings as attempts "to raise capital by capitalizing on the AI infrastructure investment boom when semiconductor stocks are hot," adding that "those funds will undoubtedly be used for capacity expansion."
Concentration Threatens Emerging Market Diversification Role
James Johnston, co-head of emerging and frontier markets at Redwheel, noted that "emerging markets have historically been viewed as markets that diversify risk and returns." The utility has disappeared as semiconductors dominate both US markets and emerging market indices. Johnston stated that "when this kind of extreme concentration appears, it often signals the peak of a cycle," warning that "cycles typically end in one of two ways: demand breaks and prices collapse, or supply floods in and prices collapse."
