Why is Doms Industries falling/rising?

As of 23-Sep, Doms Industries Ltd is experiencing a decline in its stock price, currently at Rs 2,608.00, which reflects a decrease of -16.95 or -0.65%. The stock has fallen after two consecutive days of gains, trading within a narrow range of Rs 25.1. Despite a positive performance over the past month with a return of +5.12%, the year-to-date return stands at -0.43%. The company has shown strong fundamentals, with net sales growing at an annual rate of 40.40% and a low debt-to-equity ratio, but it faces a very expensive valuation with a Price to Book Value of 15.8. Additionally, there has been a significant drop in investor participation, with delivery volume falling by -38.03% against the 5-day average, which may contribute to the stock's recent price movement.
In the broader market context, Doms Industries' short-term performance of +0.38% over the past week contrasts with the Sensex, which has declined by -0.34%. While the stock has shown resilience in the short term compared to the benchmark, its long-term performance is less favorable, with a year-over-year return of -2.82% compared to the Sensex's -3.33%. The high institutional holdings at 25.32% indicate confidence from larger investors, but the stock's expensive valuation and declining trading volume may be causing caution among retail investors, leading to the current price decline.
