Why is Fischer Medical falling/rising?

As of 21-Jul, Fischer Medical Ventures Ltd is experiencing a price increase, with its current price at 918.70, reflecting a rise of 9.35 or 1.03%. The stock has shown strong performance, outperforming its sector by 1.4% today and reaching an intraday high of Rs 958.8, which is a 5.44% increase. Over the past week, the stock has gained 12.04%, and it has consistently delivered impressive returns, including a 48.90% increase over the last year and a staggering 2151.72% over the past three years. Despite a slight decline in investor participation, indicated by a 10.99% drop in delivery volume, the stock remains liquid and is trading above its various moving averages, suggesting a positive trend.
In the broader market context, Fischer Medical's recent performance stands in stark contrast to the benchmark Sensex, which has seen a marginal decline of 0.06% over the past week. This significant outperformance highlights the stock's resilience and attractiveness to investors, particularly given its low debt-to-equity ratio and consistent returns over the last three years. The stock's ability to outperform the BSE500 in each of the last three annual periods further underscores its strong position in the market, contributing to the upward movement in its stock price.
