    Goldman Warns of KOSPI Bubble; Samsung/SK Hynix 60% of Index

    Question

    Goldman Warns of KOSPI Bubble; Samsung/SK Hynix 60% of Index

    Direct answer

    The South Korean market is experiencing a historic concentration event. With Samsung and SK Hynix making up 60% of the KOSPI, the index is no longer a broad representation of the Korean economy but a levered bet on global memory chip demand. Goldman Sachs' warning suggests that any downturn in the semiconductor cycle or regulatory changes to index weighting could trigger a systemic sell-off in Korean assets.
