Why is Dredging Corpn. falling/rising?

Over the past week, the stock has decreased by 6.06%, and it has shown a significant decline of 39.29% over the past year, indicating a troubling trend. While the company reported positive results in March 2025, including the highest operating profit to interest ratio and net sales, it faces severe long-term challenges, such as a -188.62% CAGR growth in operating profits over the last five years and a weak ability to service its debt.
Broader market context shows that the stock has significantly underperformed compared to the benchmark, with the Sensex gaining 0.12% over the past week while Dredging Corporation's stock fell. The shipping sector has seen a gain of 2.61%, further highlighting the company's struggles. Additionally, a notable drop in investor participation, with a 47.41% decrease in delivery volume, suggests waning interest in the stock. Overall, the combination of weak fundamentals, poor profitability, and negative operating profits has contributed to the stock's downward movement in the market.
