Why is Rishabh Instrum. falling/rising?

As of 29-Sep, Rishabh Instruments Ltd is experiencing a decline in its stock price, currently at Rs 384.80, which reflects a decrease of Rs 12.9 or 3.24%. The stock has underperformed its sector by 3.03% today and has been on a consecutive downward trend for the last two days, resulting in a total decline of 7.73%. Additionally, the stock has shown negative returns over the past week and month, with declines of 4.36% and 6.81%, respectively, while it has only managed a modest gain of 1.00% over the past year. The company's low debt-to-equity ratio and significant growth in net profit are positive indicators; however, the low return on equity and poor long-term growth prospects, alongside a high price-to-book value, suggest that the stock is overvalued, contributing to its recent price drop.
In the broader market context, the Sensex has decreased by 2.18% over the past week, indicating that Rishabh Instruments Ltd's short-term performance is worse than the benchmark. The stock's recent struggles are compounded by a decline in institutional investor participation, which has fallen by 0.78% in the previous quarter, suggesting a lack of confidence among more sophisticated investors. This decline in participation, combined with the company's poor management efficiency and high valuation relative to peers, has likely contributed to the stock's downward movement in the current market environment.
