Why is RBM Infracon falling/rising?

As of 18-Jul, RBM Infracon Ltd is currently priced at 485.85, reflecting a decrease of 4.25, or 0.87%. The stock has underperformed its sector today by 0.31%, despite showing higher performance compared to its 5-day, 20-day, 50-day, and 100-day moving averages, although it remains below the 200-day moving average. The stock has seen a significant increase in investor participation, with delivery volume rising by 224.23% against the 5-day average. Over the past week, RBM Infracon has experienced a return of +13.92%, contrasting with a slight decline of -0.72% in the Sensex. However, the stock's year-to-date performance remains concerning, with a decline of -33.47%, while the Sensex has gained 5.60%.
In the broader market context, RBM Infracon's performance over the last year has been notably weaker, with a return of -11.59% compared to the market's -0.36%. Despite the company's strong fundamentals, including a high return on equity of 20.92% and impressive growth in net sales and operating profit, it has struggled to keep pace with market trends. The company's low debt-to-equity ratio and consistent positive results over the last four quarters indicate potential for long-term growth, yet the stock's recent underperformance highlights the risks associated with its volatility in the market.
