Why is Dredging Corpn. falling/rising?

As of 13-Nov, Dredging Corporation of India Ltd is experiencing a decline in its stock price, currently at 777.30, which represents a decrease of 80.0 points or 9.33%. Today's performance indicates that the stock has underperformed its sector by 6.73% and opened with a loss of 3.09%. It reached an intraday low of Rs 771.6, reflecting a 10% drop. Over the past week, the stock has fallen by 10.98%, while its performance over the last month shows a gain of 27.45%. Despite a strong long-term fundamental strength characterized by low debt and a significant profit increase of 81.6% over the past year, the stock has generated a negative return of 14.77% in the last year, which may contribute to current investor sentiment. Additionally, the stock's liquidity appears adequate, but there has been a notable decline in investor participation, with delivery volume dropping by 68.25% compared to the five-day average.
Broader market context reveals that the Sensex has increased by 1.40% over the past week, contrasting with the stock's decline. This underperformance against the benchmark may reflect broader market conditions affecting the shipping sector, which has fallen by 2.73%. The stock's recent trend reversal, following two days of gains, suggests a shift in investor confidence, possibly influenced by the overall market dynamics and sector performance. While the stock remains attractive in terms of valuation compared to its peers, the current negative momentum and reduced trading volume may be causing investors to reassess their positions.
