Why is Garden Reach Sh. falling/rising?

As of 29-Sep, Garden Reach Shipbuilders & Engineers Ltd is experiencing a decline in its stock price, currently at Rs 2,493.45, which reflects a decrease of Rs 117.85 or 4.51%. The stock has been on a downward trend, having fallen consecutively for the last two days, resulting in an overall drop of 8.19% during this period. Despite outperforming its sector by 0.27% today, the stock's performance over the past week shows a decline of 6.51%. Additionally, the stock is trading below its 5-day, 20-day, 50-day, and 100-day moving averages, although it remains above the 200-day moving average. The recent drop in delivery volume by 26.4% against the 5-day average indicates a decrease in investor participation, which could be contributing to the stock's price decline.
In the broader market context, the stock's short-term performance has been notably worse than the benchmark, with the Sensex declining only 2.18% over the same week. While the company has demonstrated strong long-term fundamentals, including a low debt-to-equity ratio and significant growth in net sales and operating profit, its current valuation appears expensive compared to peers, which may deter some investors. The stock has shown impressive returns over the past year and three years, outperforming the BSE500, but the recent price drop suggests that investors are reacting to the high valuation and declining participation, despite the positive long-term outlook and increasing institutional interest.
