Key Highlights
- Samsung Electronics shares declined 7.8% to ₩330,500 Friday amid a widespread tech sector downturn in Korean equity markets
- Apple’s MacBook and iPad price increase announcement shook investor sentiment surrounding the AI hardware expansion narrative
- Single-stock leveraged ETFs amplified downward pressure on Samsung and SK Hynix shares
- The KOSPI index plummeted over 8%, activating its fifth circuit breaker halt in 2026
- Reports emerged of Samsung preparing a ₩1,000 trillion ($646 billion) decade-long capital investment strategy focused on semiconductors and AI infrastructure
Samsung Electronics shares tumbled 7.8% to close at ₩330,500 Friday, compounding losses from an already devastating week that witnessed the stock shed over 12% in just one trading day on June 23.

The earlier June 23 collapse activated the KOSPI’s fourth circuit breaker mechanism this year. Friday’s session brought the fifth, with Korea Exchange suspending all index trading for 20 minutes beginning approximately 12:10 p.m. local time after the benchmark index plunged beyond the 8% threshold.
This week’s catalyst originated from Apple, which revealed plans to raise prices across its MacBook and iPad product portfolios in response to escalating memory chip and component expenses. The announcement unnerved market participants who had positioned themselves for a prolonged AI-powered hardware expansion cycle.
The semiconductor industry absorbed the blow globally. SK Hynix, Samsung’s primary domestic competitor, experienced similar carnage — declining more than 8% — while leveraged exchange-traded funds linked to both companies collapsed over 15%.
Leveraged ETF Products Accelerated the Downturn
Single-stock leveraged ETFs designed to track Samsung and SK Hynix performance have become an increasing source of worry for South Korean financial oversight authorities. Friday’s session validated those concerns — the instruments amplified price movements far beyond what underlying business fundamentals would reasonably justify.
This created a self-reinforcing selling spiral that punished Samsung shares more severely than a straightforward interpretation of the news cycle would predict.
Japan’s Nikkei 225 index similarly retreated, demonstrating how rapidly the selling wave propagated throughout Asian markets.
Samsung had experienced substantial appreciation throughout the preceding twelve months, meaning Friday’s losses partially represent profit-taking activity following an extraordinary bull run. When market psychology shifts, the reversal can accelerate dramatically.
Massive $646 Billion Capital Plan Sparked Investor Anxiety
Market timing proved unfortunate. Domestic Korean news outlets disclosed this week that Samsung intends to unveil a ₩1,000 trillion ($646 billion) investment blueprint spanning the next ten years — potentially representing the most substantial corporate capital commitment in South Korean economic history.
The reported strategy encompasses semiconductor manufacturing facilities, artificial intelligence data center infrastructure, battery production, and display technology. Approximately ₩300 trillion targets chip fabrication plants in the nation’s southwestern region, while more than ₩350 trillion directs toward AI data center projects.
South Korean President Lee Jae Myung plans to convene a national economic strategy briefing on June 29, where Samsung Vice Chairman Jun Young-hyun and SK Hynix CEO Kwak Noh-jung will both outline their respective investment roadmaps.
Contrary to market enthusiasm, certain investors interpreted the massive spending scale as presenting considerable risk. Deploying hundreds of trillions of won into capital-intensive infrastructure amid uncertain chip demand cycles represents a substantial strategic gamble.
SK Hynix independently disclosed intentions to secure up to $29.4 billion through a Nasdaq listing of American Depositary Receipts, channeling proceeds toward new fabrication plants, advanced packaging operations, and manufacturing equipment.
Both corporate announcements arrive as South Korea attempts to defend its competitive position in the worldwide AI and semiconductor technology competition against mounting challenges from the United States and China.
SK Hynix stock traded down 8.36% at the time of publication, while Samsung recovered modestly to ₩339,500 after trimming earlier session losses.
