Why is GSFC falling/rising?

As of 22-Sep, Gujarat State Fertilizers & Chemicals Ltd. is experiencing a decline in its stock price, currently at Rs 205.75, which reflects a decrease of Rs 5.25 or 2.49%. The stock has underperformed its sector by 2.15% today, with an intraday low of Rs 204.55. Over the past week, the stock has shown a slight increase of 0.37%, but it has decreased by 2.00% over the past month. Despite a year-to-date gain of 4.18%, the stock has underperformed over the last year with a return of -5.96%. The company's financial health appears stable with a low debt-to-equity ratio and strong operating profit growth, but the stock is trading at a premium compared to its peers, which may be affecting investor sentiment.
In the broader market context, the Sensex has increased by 0.46% over the past week, indicating that the stock's short-term performance is lagging behind the benchmark. The recent decline in delivery volume suggests falling investor participation, which could further pressure the stock price. While the company has shown healthy long-term growth and high institutional holdings, the current market conditions and the stock's relative performance may be contributing to its recent price drop.
