One-Line Thesis
Korean semiconductor exposure is not one trade. It combines SK Hynix’s HBM leadership, Samsung Electronics’ memory and foundry recovery option, and KOSPI index concentration around Samsung and SK Hynix.

FAQ
What is the difference between Samsung Electronics and SK Hynix as HBM investments?
SK Hynix offers cleaner HBM exposure and stronger visibility into Nvidia-linked demand. Samsung combines HBM recovery potential with a broader memory cycle, foundry optionality and device exposure.
Why does Samsung’s KOSPI weight matter?
Samsung is the largest single component in Korean equity benchmarks. Buying Korea through ETFs often means taking meaningful exposure to Samsung, SK Hynix and the semiconductor cycle.
Is the KOSPI re-rating only about semiconductors?
No. HBM is the strongest earnings engine, but Korea’s 2026 re-rating also reflects governance reform, rising shareholder-return pressure and global allocation away from crowded US exposure.
