Why is Mangalore Chem. falling/rising?

As of 11-Sep, Mangalore Chemicals & Fertilizers Ltd is experiencing a decline in its stock price, currently at Rs 316.00, which reflects a decrease of Rs 11.8 or 3.6%. Today's price summary indicates that the stock has underperformed its sector by 4.12%, with an intraday low of Rs 315, down 3.9%. The stock has shown a negative performance over the past week and month, with declines of 9.86% and 12.19%, respectively, although it has delivered impressive returns of 144.96% over the past year. Despite positive results in the last three quarters, including a significant growth in profit after tax and a low debt-equity ratio, the stock's recent movement is affected by falling investor participation, as evidenced by a 45.13% drop in delivery volume compared to the five-day average.
In the broader market context, while Mangalore Chemicals & Fertilizers Ltd has outperformed the BSE500 in the long term, its short-term performance has been less favorable, particularly when compared to the Sensex, which has gained 1.03% over the past week. The stock's current decline contrasts sharply with its year-to-date performance of 105.53%, indicating a potential correction after a strong rally. The increase in institutional investor participation, which now holds 10.46% of the company, suggests a positive outlook from more sophisticated investors, but the recent drop in retail interest may be contributing to the stock's current downward trend.
