Why is Natco Pharma falling/rising?

As of 21-Jul, Natco Pharma Ltd. is experiencing a decline in its stock price, currently at Rs 1,014.70, which reflects a decrease of Rs 20.2 or 1.95%. Today's price summary indicates that the stock has underperformed its sector by 1.63% and has fallen after five consecutive days of gains. The stock touched an intraday low of Rs 1,009.85, representing a drop of 2.42%. Over the past week, Natco Pharma has shown a return of +3.88%, while its performance over the past month is +15.93%. However, its year-to-date return is significantly negative at -26.84%. Despite the recent downturn, the company demonstrates high management efficiency with a return on equity (ROE) of 15.57% and a low debt-to-equity ratio, suggesting a solid financial foundation. Additionally, the stock is trading at a discount compared to its peers, with a price-to-book value of 2.4, and has seen a profit increase of 35.8% over the past year, although its stock price has declined by -17.11% during the same period.
In the broader market context, the Sensex has shown a slight decline of -0.06% over the past week, indicating that the market overall is relatively stable. However, Natco Pharma's performance has outpaced the benchmark in the short term, suggesting that its recent price movement is more influenced by company-specific factors rather than broader market trends. The falling investor participation, with a delivery volume decrease of 27.18% against the five-day average, may also contribute to the stock's downward pressure. While institutional holdings are high at 21.33%, indicating confidence from larger investors, the recent price drop reflects a combination of short-term volatility and the stock's struggle to maintain momentum despite its underlying financial strengths.
