Samsung and SK Hynix Surge 6-11% in Korea as Semiconductor Duo Recovers; Growth Fund Expands to ₩200T

The Quick Take

• Samsung Electronics surged 6.27% in morning trade, recapturing the ₩280,000 level, while SK Hynix gained 8.64–11.3%, recovering ₩200M—both at key technical thresholds.
• The semiconductor duo's recovery was driven by overnight memory sector strength in US markets, with global peers also rallying.
• South Korea's Financial Services Commission announced expansion of the National Growth Fund from ₩150 trillion to ₩200 trillion, adding space, aerospace and deep-tech mandates.
• The combined policy and price recovery represents the most significant single-day positive catalyst for Korean tech equities in months.

South Korea's two semiconductor giants staged a powerful coordinated recovery in morning trading on July 15, with Samsung Electronics recovering the psychologically important ₩280,000 mark and SK Hynix breaching ₩210 million as US memory peers rallied overnight on NYSE. The dual recovery is technically significant because both stocks had been trading below these key price levels for an extended period, and the simultaneous recapture—driven by overnight US memory sector momentum—signals institutional confidence that the sector's earnings trajectory is stabilising. For the KOSPI, which is heavily weighted in these two names, the intraday gains carry meaningful index-level implications for Korean market performance.

Samsung and SK Hynix's outsized gains reflect broader dynamics in the global memory semiconductor cycle: DRAM and NAND pricing that had been under pressure through late 2025 are now showing signs of recovery as AI server build-outs drive high-bandwidth memory (HBM) demand to record levels. Samsung's 6.27% gain and SK Hynix's 8.64-11.3% move in a single session indicate short-covering alongside genuine institutional accumulation. The simultaneous policy announcement of Korea's National Growth Fund expansion to ₩200 trillion—with new mandates covering space, aerospace and emerging technologies—adds a second positive catalyst for domestic tech investment sentiment and broadens the investment universe for the fund.

The forward signals for Korea's semiconductor sector are the quarterly earnings from Samsung and SK Hynix—expected in late July—where management commentary on HBM ramp volumes, DRAM contract price negotiations and AI data centre customer pipeline will validate or challenge the market's recovery thesis. Watch Micron Technology's quarterly results (US-listed peer) for a Western cross-check on memory pricing dynamics. The macro variable is AI server capex: NVIDIA's next GPU release cycle and hyperscaler build-out rates directly determine HBM demand, which has been SK Hynix's key margin driver. The National Growth Fund expansion details—specifically which companies and sectors qualify—will be the domestic policy catalyst to watch in coming weeks.
