Why is Dredging Corpn. falling/rising?

As of 14-Jul, Dredging Corporation of India Ltd is experiencing a decline in its stock price, currently at 683.25, reflecting a decrease of 2.3 points or 0.34%. The stock has been on a downward trend, having fallen consecutively for the last three days, resulting in a total decline of 1.82% during this period. Additionally, the stock's performance over the past week shows a loss of 1.55%, while its one-month return is down by 5.91%. Despite some positive results reported for March 25, including the highest operating profit to interest ratio and net sales, the company faces significant challenges, including a weak long-term fundamental strength indicated by a -188.62% CAGR growth in operating profits over the last five years and a negative EBIT to interest ratio. Furthermore, falling participation from institutional investors, who have decreased their stake, adds to the stock's negative outlook.
In the broader market context, the Dredging Corporation of India Ltd has underperformed compared to the Sensex, which has gained 1.40% over the past month, while the stock has declined by 5.91%. Over the past year, the stock has generated a staggering negative return of -48.05%, contrasting sharply with the market's positive return of 2.15%. This significant underperformance, coupled with declining investor participation and liquidity issues, suggests a challenging environment for the stock, contributing to its current price decline.
