Why is Garden Reach Sh. falling/rising?

As of 19-Sep, Garden Reach Shipbuilders & Engineers Ltd is experiencing a decline in its stock price, currently at 2,604.10, which represents a decrease of 22.6 points or 0.86%. Today's price summary indicates that the stock has underperformed its sector by 0.52% and has fallen after two consecutive days of gains. Despite this recent downturn, the stock has shown impressive performance over the longer term, with a year-to-date increase of 60.98% and a remarkable 641.28% rise over the past three years. The company benefits from strong fundamentals, including a low debt-to-equity ratio and significant growth in net sales and operating profit. However, it is trading at a premium valuation compared to its peers, which may contribute to the current price decline.
In the broader market context, the stock's short-term performance has lagged behind the benchmark, with a 1-week return of 0.57% compared to the Sensex's 0.88%. While institutional investors have increased their stake, indicating confidence in the company's long-term prospects, the stock's recent price movement suggests that market participants may be reacting to its high valuation and the potential for a correction after a period of strong gains. The combination of these factors, including rising investor participation and consistent returns over the last three years, contrasts with the current price drop, highlighting the complexities of market sentiment and valuation dynamics.
