Why is GSFC falling/rising?

As of 15-Jul, Gujarat State Fertilizers & Chemicals Ltd. is experiencing a price increase, currently at Rs 204.60, reflecting a rise of Rs 3.7 or 1.84%. Today's price summary indicates that the stock has gained after four consecutive days of decline, reaching an intraday high of Rs 206.65. However, it underperformed its sector by 0.58% and has seen a significant drop in delivery volume, falling by 39.04% against the five-day average. Over the past week, the stock has decreased by 1.30%, while it has shown a modest gain of 0.39% over the past month. Despite a substantial year-over-year decline of 19.42%, the company has demonstrated healthy long-term growth, with operating profit increasing at an annual rate of 24.63%, and positive quarterly results indicating substantial growth in both profit before tax and profit after tax.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has declined by 1.36% over the past week but has outperformed GSFC in the month with a gain of 1.79%. The fertilizer sector overall has seen a positive movement, gaining 2.37%. The stock's high institutional holdings of 24.63% suggest confidence from larger investors, who typically have better resources for analyzing company fundamentals. However, the stock's premium valuation compared to peers and a PEG ratio of 2.9 indicates that while the company is performing well operationally, it may be facing challenges in market perception, contributing to its recent price fluctuations.
