Woofun AI reports that Goldman Sachs analysts Timothy Moe and John Kwon stated a 1 percentage point increase in the combined index weight of Samsung and SK Hynix could result in approximately $20 billion in foreign capital outflows from the Korean market. This potential withdrawal stems from requirements under the U.S. Investment Company Act regarding portfolio diversification thresholds.

The firm noted that significant inflows into leveraged ETFs, alongside increased options and margin retail trading, have created a structural environment where daily price swings exceed fundamental support. With asset management growth driven by investment gains rather than new capital, rising valuations are increasing institutional exposure to mechanical volatility, meaning even moderate pullbacks could trigger forced sell-offs.
