Trader consensus pricing "No" at 72.5% for the KOSPI reaching its all-time high before 2028 stems primarily from the index's steep 37% correction since the June 2026 peak near 9,114, driven by mounting doubts over the sustainability of AI-related capital expenditures, elevated U.S. Treasury yields above 5%, and sustained foreign investor outflows. Heavy concentration in Samsung Electronics and SK Hynix amplifies downside volatility amid Chinese semiconductor competition and questions about debt-funded AI infrastructure returns. With the benchmark near 5,736 and forward P/E ratios at multi-decade lows, near-term catalysts such as FOMC decisions, major tech earnings, and confirmation of semiconductor profit resilience will determine whether the market can close the gap by end-2027.
