Why is Garden Reach Sh. falling/rising?

As of 11-Jul, Garden Reach Shipbuilders & Engineers Ltd is experiencing a decline in its stock price, currently at Rs 2,801.60, reflecting a decrease of Rs 94.2 or 3.25%. The stock has underperformed its sector by 1.59% today and has been on a consecutive downward trend for the last two days, with a total drop of 5.95% during this period. Additionally, the stock's performance over the past week shows a decline of 5.77%, while its year-to-date return remains strong at 73.19%. Despite the company's solid fundamentals, including a low debt-to-equity ratio and significant growth in net sales and operating profit, the stock is currently facing pressure due to a high valuation and falling investor participation, as indicated by a decrease in delivery volume.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has only declined by 1.12% over the past week. While Garden Reach Shipbuilders has shown impressive long-term returns, outperforming the BSE500 consistently over the last three years, its short-term struggles highlight a disconnect between its strong fundamentals and current market sentiment. The stock's high price-to-book value and premium valuation compared to peers may also be contributing to the recent price decline, as investors reassess their positions in light of the company's recent performance and market conditions.
