Why is Astra Microwave falling/rising?

As of 30-Jun, Astra Microwave Products Ltd is experiencing a decline in its stock price, currently at Rs 1,041.55, which reflects a decrease of Rs 15.65 or 1.48%. The stock has underperformed its sector by 3.06% today and has been on a consecutive downward trend for the last two days, with a total decline of 2.22%. In the past week, the stock has fallen by 8.65%, while over the past month, it has decreased by 4.82%. Despite these short-term declines, the stock has shown strong long-term growth, with a year-to-date increase of 35.39% and a remarkable 427.90% rise over the past three years. The company has a low Debt to EBITDA ratio of 0.62 times, indicating a strong ability to service debt, and has reported healthy operating profit growth at an annual rate of 32.76%. However, the stock is considered very expensive with a high PEG ratio of 2.4, which may be contributing to the recent price decline.
In the broader market context, Astra Microwave's short-term performance has been significantly weaker than the benchmark, with the Sensex gaining 2.09% over the past week and 2.65% over the past month. This stark contrast highlights the stock's recent struggles in comparison to the overall market. Additionally, while the stock has high institutional holdings at 20.61%, which typically indicates confidence from knowledgeable investors, the recent price movements suggest that market sentiment may be shifting due to its high valuation compared to peers. The combination of short-term underperformance and high valuation concerns appears to be influencing the stock's current downward trajectory.
