Why is Mangalore Chem. falling/rising?

As of 12-Sep, Mangalore Chemicals & Fertilizers Ltd is experiencing a decline in its stock price, currently at Rs 306.10, which reflects a decrease of Rs 9.9 or 3.13%. The stock has underperformed its sector by 2.58% today and has been on a consecutive downward trend for the last two days, resulting in a total drop of 6.62% during this period. Additionally, the stock has seen a significant decline of 11.38% over the past month, despite a strong year-to-date performance of 99.09%. The recent trading activity indicates a lower delivery volume, which has decreased by 31.29% compared to the five-day average, suggesting reduced investor interest. However, the company has reported positive financial results over the last three quarters, with a notable growth in profit after tax and a low debt-equity ratio, which could provide some support to the stock.
In the broader market context, the stock's recent performance contrasts sharply with the Sensex, which has gained 1.48% over the past week. While Mangalore Chemicals has generated impressive returns of 137.66% over the past year, its short-term performance has lagged behind the benchmark, indicating a potential disconnect between the company's long-term fundamentals and current market sentiment. The increase in institutional investor participation, which has risen by 0.74% in the last quarter, may suggest confidence in the company's long-term prospects, but the immediate market reaction appears to be influenced by recent price declines and lower trading volumes.
