Why is Mangalore Chem. falling/rising?

As of 26-Sep, Mangalore Chemicals & Fertilizers Ltd is experiencing a decline in its stock price, currently at Rs 312.65, which reflects a decrease of Rs 14.6 or 4.46%. The stock has been underperforming, having fallen consecutively for the last two days with a total decline of 5.76%. Although it opened with a gain of 3.56% today and reached an intraday high of Rs 338.9, it also touched a low of Rs 310.4, indicating high volatility with an intraday fluctuation of 7.02%. Over the past month, the stock has decreased by 12.04%, contrasting with its impressive year-to-date return of 103.35% and a remarkable 148.43% increase over the past year. Despite positive results in the last three quarters and an increase in institutional investor participation, the stock's recent performance has been negatively impacted by a significant drop in delivery volume and a general decline in the fertilizer sector.
In the broader market context, Mangalore Chemicals & Fertilizers Ltd has underperformed against the benchmark Sensex, which has decreased by 2.66% over the past week, while the stock itself has gained 2.26% in the same timeframe. This indicates that while the stock has shown some resilience in the short term, it is still facing challenges compared to the overall market. The fertilizer sector has also seen a decline of 2.27%, contributing to the stock's struggles. The falling investor participation and the stock's volatility suggest a cautious sentiment among investors, despite the company's strong long-term performance and fundamentals.
