Why is Cochin Shipyard falling/rising?

As of 29-Sep, Cochin Shipyard Ltd's stock price is currently at Rs 1,780.00, reflecting a decrease of Rs 93.5, or 4.99%. The stock has been experiencing a downward trend, having lost 7.58% over the last two days, with an intraday low of Rs 1,755. The stock's performance today is in line with the sector, which has seen a decline of 4.38%. Despite a strong performance over the longer term, with a year-to-date increase of 15.60% and a remarkable 721.60% rise over the past three years, the recent negative movement is compounded by falling investor participation, as evidenced by a 23.26% drop in delivery volume compared to the five-day average. The company maintains a low debt-to-equity ratio and has reported positive financial results, including a 37.36% growth in net sales over the last six months, which suggests underlying strength despite the current price decline.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has only declined by 2.18% over the past week. This indicates that while Cochin Shipyard is facing short-term challenges, it has outperformed the benchmark significantly over longer periods, such as a 10.64% increase over the past month compared to the Sensex's 0.70%. The overall shipbuilding sector's decline and the stock's recent consecutive falls suggest that external market pressures are influencing its current price movement, despite the company's solid fundamentals and consistent returns over the last three years.
