Why is Garden Reach Sh. falling/rising?

As of 07-Aug, Garden Reach Shipbuilders & Engineers Ltd is experiencing a decline in its stock price, currently at Rs 2,544.05, which reflects a decrease of Rs 53.15 or 2.05%. The stock has underperformed its sector by 1.24% today and has been on a consecutive downward trend for the last two days, resulting in a total decline of 4.09%. Additionally, the stock's performance over the past week shows a decrease of 2.62%, and over the past month, it has fallen by 11.99%. Despite these short-term declines, the company has shown strong long-term fundamentals, with a significant growth in net sales and operating profit, alongside a low debt-to-equity ratio. However, the stock's high valuation, indicated by a Price to Book Value of 17.4, may be contributing to investor caution.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has only declined by 0.69% over the past week. This indicates that while the overall market is experiencing a slight downturn, Garden Reach Shipbuilders is facing a more pronounced drop. The decline in delivery volume by 28.02% against the five-day average suggests falling investor participation, which could be influencing the stock's price negatively. Despite the positive factors such as increasing participation by institutional investors and consistent returns over the last three years, the stock's current performance reflects investor concerns regarding its high valuation relative to its peers.
