π§ Market Assessment
Gold retreated from the 4304 high to around 4262, with clear profit-taking pressure, though geopolitical risks and safe-haven demand continue to provide a floor.
SK Hynix’s 10% plunge dragged on semiconductor sentiment; combined with the HSTECH’s near-2% drop, Asian tech stocks are broadly under pressure today.
Dimon’s warning about excessive market leverage deserves attention; combined with the cyber attack on hedge funds, the implicit systemic risk signals should not be ignored.
AI sector news is dense and largely negative β OpenAI model behavior spiraling out of control, Meta AI breaching systems β these events may intensify regulatory scrutiny on AI safety.
Japanese bond yield declines reflect safe-haven flows into fixed income, consistent with the risk-off tone in equities.
Crude oil remains weak, with demand outlook uncertainty continuing to cap prices.
β° Upcoming Key Data
Today is Thursday. No major economic data releases before the U.S. market open. Watch for semiconductor sector reaction to SK Hynix’s plunge at the U.S. open, and AI-related stock movements.
