Why is Mazagon Dock falling/rising?

As of 29-Sep, Mazagon Dock Shipbuilders Ltd is experiencing a decline in its stock price, currently at Rs 2,749.45, which reflects a decrease of Rs 79.8 or 2.82%. The stock has been on a downward trend for the past six days, resulting in a total drop of 7.93% during this period. Despite outperforming its sector by 1.96% today, the stock's performance has been negatively impacted by a significant fall in investor participation, with delivery volume decreasing by 19.55% against the five-day average. Additionally, the stock's recent financial results have shown a decline in profit before tax, profit after tax, and net sales compared to previous quarters, which has raised concerns among investors. While the company has strong long-term fundamentals, including a healthy return on equity and consistent growth, the recent negative financial performance and a decrease in promoter confidence, with a 3.61% reduction in their stake, have contributed to the stock's current decline.
In the broader market context, the stock has underperformed the benchmark Sensex over the past week, with a decline of 7.58% compared to the Sensex's 2.18% drop. However, over the past month, Mazagon Dock has shown a positive return of 5.51%, while the Sensex has only increased by 0.70%. This indicates that while the stock has faced recent challenges, it has had a stronger performance in the longer term, with a year-to-date return of 23.41% compared to the Sensex's 2.85%. The overall shipbuilding sector has also seen a decline of 4.38%, which may be influencing the stock's performance as well.
