SUMCO Corp. Stock Hits Day Low Amid Price Pressure, Closes at JPY 1,443.00

SUMCO Corp., a mid-cap player in the industrial manufacturing sector, has experienced significant volatility today, with the stock hitting an intraday low of JPY 1,443.00. The stock has declined by 6.34% on November 5, 2025, underperforming the Japan Nikkei 225, which fell by 1.74% during the same period.
Over the past week, SUMCO Corp. has seen a decrease of 7.19%, and its performance over the last month has been even more pronounced, with a drop of 12.78%. Despite a modest annual return of 2.96%, the company has struggled in the longer term, with a three-year performance decline of 20.73% and a five-year decrease of 8.23%.

Financial metrics indicate challenges, including a return on capital employed (ROCE) of just 1.75% and a high debt-equity ratio of 48.11%. The inventory turnover ratio stands at a low 1.43%, reflecting potential inefficiencies. While the stock trades at a price-to-book value of 0.75, it has generated a return of only 7.94% over the past year, significantly lagging behind the market's performance.
