Why is Natco Pharma falling/rising?

As of 07-Jul, Natco Pharma Ltd. is currently priced at 972.00, reflecting a decrease of 26.3 points or 2.63%. The stock has underperformed its sector today by 2.55%, following a trend reversal after two consecutive days of gains. It reached an intraday low of Rs 970.6, indicating a decline of 2.77%. In the past week, the stock has shown a positive return of 4.82%, but it has a year-to-date return of -29.92%. Despite the recent downturn, the company maintains high management efficiency with a return on equity (ROE) of 15.57%, a low debt-to-equity ratio, and healthy long-term growth, as evidenced by a 32.35% annual increase in operating profit. The stock is trading at a discount compared to its peers, with a PEG ratio of 0.3, which suggests it may be undervalued despite its recent price drop.
In the broader market context, the Sensex has experienced a slight decline of 0.20% over the past week, while Natco Pharma has outperformed this benchmark. However, the stock's year-to-date performance is significantly lagging behind the Sensex's 6.79% increase. The recent fall in investor participation, with a 5.55% decrease in delivery volume, may indicate waning interest, which could further pressure the stock price. High institutional holdings at 23.15% suggest that informed investors are backing the company, but the current market conditions and the stock's recent performance may be causing caution among retail investors.
