Why Did SK Hynix Surge 29.9% to Drive KOSPI? H2 Outlook for AI Semiconductor Stocks
Driven by massive foreign net buying, SK Hynix surged 29.9% to hit the daily limit. We analyze the core factors behind the explosive AI semiconductor demand and the record-breaking KOSPI rally.
SK Hynix hit the daily limit, surging 29.9%. The KOSPI index closed at 6,595 points, marking a record-breaking rally fueled by 7 trillion won in foreign net buying.
Explosive AI Semiconductor Demand: Background of SK Hynix and Hanmi Semiconductor's Surge
On the 2nd, the domestic stock market (KOSPI) showcased an unprecedented bull market, driven by record-breaking surges in AI semiconductor-related stocks. SK Hynix saw a massive influx of foreign buying right from the opening bell, soaring 29.9% during the session and effectively locking in at the upper limit. Alongside this, Hanmi Semiconductor also skyrocketed over 20% on expectations of increased demand for HBM (High Bandwidth Memory) core equipment, leading the AI rally.
The core driving force behind this rally is the combination of global big tech companies announcing expanded capital expenditures (CAPEX) for AI data centers and Nvidia's robust demand outlook. Positive earnings guidance, which quelled recent concerns of an 'AI bubble' in the global market, has caused global capital to strongly pivot back to top-tier domestic semiconductor stocks. Foreign investors aggressively net-bought 7 trillion won in the KOSPI market in a single day, pushing the index up to 6,595 points.
Revaluation of Domestic Semiconductors Amid the Great Rotation
Recently, a 'Great Rotation' phenomenon—where capital shifts from mega-cap tech stocks to value and traditional industry stocks—has been observed in the US stock market. However, as the Dow Jones and Nasdaq rise simultaneously on tech-centric buying and positive economic indicators, global capital remains laser-focused on the AI hardware value chain that guarantees 'solid earnings.' Samsung Electronics also broke through 262,500 won after reporting record earnings in its semiconductor division, suggesting that Korea's top two semiconductor giants are being upgraded to top priorities in global portfolios.
FAQ: Most Frequently Asked Questions by Investors
Q1. Is there further upside potential for SK Hynix?
As the company virtually monopolizes the supply of the latest high-bandwidth memory (such as HBM3E) to Nvidia, the global leader in AI chip demand, additional earnings surprises are expected in the second half of the year. However, short-term profit-taking may occur due to the rapid surge, so a split-purchase approach is recommended for new entries.
Q2. Can the KOSPI maintain its breakthrough above 6,500 points?
The 7 trillion won net buying by foreign investors is highly likely to be mid-to-long-term capital betting on the fundamental improvement of domestic semiconductor companies, rather than a one-off event. Coupled with expectations of a rate cut by the Bank of Korea in the second half of the year, there is a high probability of attempting to settle at a new upper box level backed by abundant liquidity.
Q3. Will the demand spread to other AI-related stocks?
A trickle-down effect is expected, where warmth spreads to materials, parts, and equipment (SME) companies after large-cap stocks surge first. Hanmi Semiconductor's 20% surge is the starting gun, and interest in packaging and testing-related companies will continue to grow.
