Why is Sumitomo Chemi. falling/rising?

As of 29-Sep, Sumitomo Chemical India Ltd is experiencing a decline in its stock price, currently at Rs 533.00, reflecting a decrease of Rs 2.3 or 0.43%. The stock has been on a downward trend, losing value for the past six days and accumulating a total decline of 11.1% during this period. Despite opening with a gain of 3.48% today and reaching an intraday high of Rs 553.95, the overall performance has been negative, with the stock trading below all key moving averages. Additionally, there has been a significant drop in investor participation, with delivery volume decreasing by 47.62% compared to the five-day average. Although the company shows strong management efficiency with a high return on equity of 19.61% and a low debt-to-equity ratio, these positive factors have not been sufficient to counteract the recent price decline.
In the broader market context, the stock's performance over the past week has been notably worse than the benchmark Sensex, which has declined by 2.18% compared to Sumitomo Chemical's 8.64% drop. Over the past month, while the stock has decreased by 4.92%, the Sensex has shown a slight increase of 0.70%. Year-to-date, Sumitomo Chemical's performance is relatively flat at -0.37%, contrasting with the Sensex's gain of 2.85%. This underperformance in both short-term and longer-term comparisons suggests that investor sentiment may be negatively impacted, despite the company's solid financial metrics.
