Why is Mangalore Chem. falling/rising?

As of 18-Sep, Mangalore Chemicals & Fertilizers Ltd is experiencing a decline in its stock price, currently at 303.90, which represents a decrease of 1.2 or 0.39%. The stock has been losing for the last two days, with a total return of -1.11% during this period. Despite outperforming its sector by 0.56% today, the stock has shown a significant decline of 12.60% over the past month, while it has generated impressive returns of 140.05% over the last year. The company has reported positive results for the last three consecutive quarters, with strong operating profit metrics and a low debt-equity ratio, which typically would support a stable stock price. However, the recent drop in delivery volume by 55.28% against the five-day average indicates a decrease in investor participation, which may be contributing to the stock's downward movement.
In the broader market context, Mangalore Chemicals & Fertilizers Ltd's short-term performance is notably weaker compared to the benchmark, as it has declined by 3.83% over the past week while the Sensex has increased by 1.80%. This contrast highlights the stock's underperformance relative to the market, despite its strong long-term returns, which have outpaced the BSE500 over multiple time frames. The increasing stake of institutional investors, who now hold 10.46% of the company, suggests a level of confidence in the company's fundamentals, yet the recent price movement reflects a lack of momentum in the short term, potentially influenced by reduced retail investor activity.
