Why is Natco Pharma falling/rising?

As of 28-Jul, Natco Pharma Ltd. is experiencing a decline in its stock price, currently at Rs 941.85, which reflects a decrease of Rs 25.95 or 2.68%. The stock has been underperforming, having fallen consecutively for the last three days with a total return drop of 8.96%. Today's trading saw the stock reach an intraday low of Rs 937.5, and it has underperformed its sector by 2.76%. Over the past week, the stock has decreased by 7.18%, while its year-to-date performance shows a significant decline of 32.09%. Despite a healthy long-term growth rate in operating profit and a high return on equity (ROE), the stock's recent performance has been negatively impacted by falling investor participation, as evidenced by a 34.52% drop in delivery volume compared to the five-day average.
In the broader market context, Natco Pharma's short-term performance has lagged behind the Sensex, which has only declined by 1.59% over the same week. While the stock has shown some resilience over a longer three-year period with a return of 38.27%, its recent struggles highlight a disconnect between its strong fundamentals—such as a low debt-to-equity ratio and high institutional holdings—and its market performance. The stock is currently trading at a discount compared to its peers, which may indicate potential for recovery; however, the recent trend suggests that investor sentiment remains cautious, contributing to its ongoing decline.
