  "account": "Sumitomo Metal Mining's stock experienced a significant 9.8% drop on Wednesday, trading at ¥10,235. This decline was a result of a widespread sell-off on the Tokyo Stock Exchange, which affected various sectors. The non-ferrous metals and mining company, known for its high beta compared to the Nikkei 225, was among the most impacted stocks in the market as risk appetite diminished across the board. The severe drop in Sumitomo Metal Mining's stock was further amplified by a sector-wide decline in non-ferrous metals, particularly gold. The company's direct competitor, Mitsubishi Materials, also saw a substantial decrease in its share price, indicating that the pressure was not unique to Sumitomo Metal Mining but rather industry-wide. The overall market sentiment was dismal, with the Nikkei 225 plummeting nearly 3% due to a broad decline in risk-driven assets. This negative market environment was exacerbated by a sharp increase in 10-year Japanese government bond yields, reaching their highest level since 1996 and crossing the 3% threshold.",
