US IT/Semiconductors +5.74%, Is That Momentum for Samsung and SK Hynix?
The US IT and semiconductor sector jumped +5.74%, creating momentum for Korean chip names.
However, nearly $1 billion inflows to spot Bitcoin ETFs and a separate report of $592 million outflows are causing high sentiment volatility.
KOSPI closed at 7,017.91 with a small gain, while KOSDAQ fell to 834.38, showing sector-level divergence.
Why did US IT and semiconductors rally so much?
IT and semiconductors: +5.74%
Healthcare: +0.75%
Energy: -3.21%
The market is repricing semiconductor and AI chip demand in the US.
Term note: HBM stands for high bandwidth memory, a type of memory used in AI data centers.
Crypto ETF flows are mixed, what does that mean?
Spot Bitcoin ETF Monday inflows: nearly $1 billion attracted
Recent reports: Bitcoin and Ethereum ETFs $592 million outflows also reported
The volatile crypto fund flows increase sentiment uncertainty.

Stocks and themes to watch in Korea
Samsung Electronics and SK Hynix were mentioned as direct or indirect beneficiaries of the US semiconductor rally.
HBM-related names showed movement as HBM demand stories gained attention in the US.
Secondary batteries and solid-state batteries showed mixed signals, suggesting sector-level differentiation.
Retail question: "So should I just buy HBM now?"
No, you should consider short-term overheating, global ETF flows, interest rates, and supply-demand together.
So, up or down?
Downward pressures
- Energy sector, -3.21%, potential to push risk-off behavior
- Bitcoin and Ethereum ETF outflow reports, $592 million, psychological selling factor
- KOSDAQ weakness, 834.38, reflecting tech uncertainty
Supporting factors
- US IT and semiconductor strength, +5.74%, momentum for Korean semiconductors
- Large spot Bitcoin ETF inflow, nearly $1 billion, a risk-asset demand signal
- KOSPI small prior-day rise, 7,017.91, possible base-building sign
