Why is RBM Infracon falling/rising?

As of 17-Nov, RBM Infracon Ltd's stock price is rising, currently at 506.05, reflecting an increase of 27.5, or 5.75%. The stock has shown strong performance today, outperforming its sector by 5.46%. Additionally, it is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating positive momentum. The stock has also experienced a significant increase in investor participation, with delivery volume rising by 69.1% compared to the 5-day average. Over the past week, RBM Infracon has returned 15.31%, significantly outperforming the Sensex, which only returned 1.72%. However, it has underperformed over the longer term, with a year-to-date return of -30.70% compared to the Sensex's 10.02%.
The company's strong fundamentals contribute to its recent price movement, highlighted by a high return on equity (ROE) of 16.24% and a low debt-to-equity ratio of 0.02. Furthermore, RBM Infracon has demonstrated impressive growth in net sales and operating profit, with net sales increasing at an annual rate of 69.80% and operating profit at 155.66%. Despite these positive indicators, the stock has struggled over the past year, generating a return of -31.36%, which contrasts sharply with the broader market's performance. This underperformance, coupled with an expensive valuation reflected in a price-to-book ratio of 3, suggests that while the stock is currently rising, it faces challenges in maintaining this momentum in the context of its longer-term performance.
