Why is Natco Pharma falling/rising?

As of 30-Jul, Natco Pharma Ltd. has seen its stock price rise to 975.35, reflecting an increase of 16.0 or 1.67%. The stock has outperformed its sector by 1.33% today and has been on a consecutive gain for the last two days, accumulating a total return of 3.56% during this period. Despite a recent decline of 5.72% over the past week and a significant drop of 29.68% year-to-date, the company has shown healthy long-term growth with an annual operating profit increase of 32.35%. The stock is trading at a discount compared to its peers, supported by a high return on equity (ROE) of 24.8 and a low debt-to-equity ratio, which enhances its attractiveness to investors.
In the broader market context, while Natco Pharma has underperformed the Sensex with a year-to-date decline of 29.68% compared to the benchmark's gain of 4.28%, it has shown resilience in the short term with a 5.18% increase over the past month against the Sensex's 2.54% decline. The stock's liquidity remains adequate for trading, although there has been a notable decrease in delivery volume, indicating a potential concern regarding investor participation. High institutional holdings at 21.33% suggest that more knowledgeable investors are backing the stock, which may contribute to its recent positive price movement despite the overall challenging market conditions.
