Woofun AI data shows that the combined weight of Samsung Electronics and SK Hynix in the South Korean KOSPI index has reached a record 60%, up from approximately 40% two years ago, driven by global artificial intelligence demand.

Regulatory authorities suspended KOSPI trading twice last week to stabilize confidence, while plans to introduce index options for SK Hynix were delayed. Matthew Lachet of Baocheng Securities stated that crowded positions in these stocks signal significant concentration risk and expected high volatility.
