Why is Garden Reach Sh. falling/rising?

As of 06-Aug, Garden Reach Shipbuilders & Engineers Ltd is experiencing a decline in its stock price, currently at Rs 2,597.00, which reflects a decrease of Rs 55.55 or 2.09%. Today's price summary indicates that the stock has underperformed its sector by 0.68% and has fallen after two consecutive days of gains. The stock reached an intraday low of Rs 2,583.75, and trading volume has decreased significantly, with delivery volume down by 20.27% compared to the five-day average. Despite a strong long-term performance, with a year-to-date return of 60.54% and a three-year return of 926.28%, the recent price movement suggests some investor caution, possibly due to its high valuation metrics and declining participation.
In the broader market context, the stock's recent performance contrasts with the benchmark Sensex, which has seen a decline of 1.15% over the past week. While Garden Reach Shipbuilders has shown robust long-term fundamentals, including a low debt-to-equity ratio and strong growth in net sales and profits, its current valuation appears expensive compared to peers, which may be contributing to the recent price drop. Institutional investors have increased their stake, indicating confidence in the company's long-term prospects, but the recent underperformance and falling investor participation suggest a cautious sentiment among retail investors.
