South Korean stocks are trading at historically extreme valuations — the KOSPI's forward P/E has dropped below 5x, the lowest in at least 20 years and roughly half its long-term average of ~10x.

The index is down -30% from its June peak, marking its deepest drawdown (-39%) since the Global Financial Crisis.

At current levels, the market is pricing in a ~50% collapse in earnings — driven by expectations of cooling demand for semiconductors and memory chips. The last time valuations implied a shock of this magnitude was during the GFC, when earnings actually fell -45%.

This is either an extreme value opportunity or a warning that earnings deterioration could be far worse than consensus expects. Markets don't price in this kind of discount without reason.

For growth and momentum traders, this sets up an interesting rotation question: if semis and memory cool further, where does capital flow next? And if Korea bottoms here, the snapback could be violent.
