π§ Strategic Assessment
The KOSPI’s 8% crash is today’s biggest risk event. Samsung’s “record profit yet circuit breaker” pattern reveals that AI chip expectations have been extremely overextended, with the “buy-the-rumor, sell-the-fact” dynamic now unleashing concentrated selling across Asian semiconductor names.
The Strait of Hormuz vessel attack signals that the brief US-Iran de-escalation window is again at risk of breaking. Should the situation escalate, crude supply will face direct impact β WTI at $69 is not yet fully pricing in this geopolitical risk.
The timing of the PCE methodology change is highly sensitive. “Manually cooling” inflation data against the backdrop of Trump’s public pressure for rate cuts could undermine the credibility of the Fed’s data-dependent framework.
Japan’s strong 30-year bond demand coexists with yen depreciation warnings. Fiscal sustainability under a 240% debt-to-GDP ratio is becoming a market focal point, with the risk of USD/JPY sliding toward 170 accumulating.
The 30%+ AI industry growth and $800B China semiconductor market data confirm the industrial trend, but Samsung’s circuit breaker serves as a reminder: being right on the trend does not mean stocks only go up.
