Summary table: Typical foreign responses by range

Detailed patterns and reasons by range

1) KRW strong range

• Observed when global risk appetite recovers or foreign capital flows in. Foreign investors tend to selectively buy relatively undervalued large caps or names with improving net income expectations. Exchange rate itself acts as background for flows rather than a direct buy signal.

2) Neutral range

• When the rate lacks a clear trend, trading is driven by company earnings, valuation, and sector momentum, producing differentiated stock-level trades. Aggregate foreign flows often alternate between net buying and net selling, making them sensitive to short-term supply-demand shifts.

3) KRW weak range

• Persistent dollar strength leads foreigners to trim positions amid currency risk and profit concerns. Reactions may differ across domestic consumption and financial sectors versus exporters, and firms with large foreign-currency liabilities may face higher scrutiny.

4) Sharp moves and event responses

• Geopolitical events, surprise central bank policy moves, or global growth shocks can trigger short-term large-scale foreign selling. In those periods, exchange rate and equity prices often fall together or move in tandem.

Practical notes for practitioners

• Exchange rate is only one explanatory variable for foreign flows. Consider it together with interest rates, earnings, and global fundamentals.
• Numeric thresholds for ranges change with time and policy. Verify current levels with broker reports or relevant institutions.
