Why is Chemcon Special. falling/rising?

As of 17-Sep, Chemcon Speciality Chemicals Ltd is currently priced at 236.80, reflecting a decrease of 0.1, or 0.04%. The stock has been underperforming, having lost 1.07% over the last three days and is down 5.03% over the past week. Additionally, it has shown a significant decline of 18.30% over the past year and a drastic 45.22% drop over the last three years, contrasting sharply with the Sensex's performance. The stock's delivery volume has also seen a considerable decline, falling by 79.08% against the 5-day average, indicating a decrease in investor participation. However, the company maintains a low debt-to-equity ratio, which is a positive factor that could support its stability despite the recent price decline.
Broader market context indicates that Chemcon's recent performance is lagging behind the benchmark, with the Sensex gaining 1.56% over the past week while Chemcon has declined. In the short term, the stock's performance is not only underwhelming compared to the benchmark but also reflects a broader trend of falling investor interest. Despite a positive return of 6.00% over the past month, the recent consecutive falls and underperformance against the sector suggest that investor sentiment may be shifting negatively, contributing to the stock's current downward trajectory.
