Why is Natco Pharma falling/rising?

As of 10-Jul, Natco Pharma Ltd. is experiencing a decline in its stock price, currently at Rs 999.55, which reflects a decrease of Rs 17.75 or 1.74%. Today's price summary indicates that the stock has underperformed its sector by 1.17% and has fallen after two days of consecutive gains. The stock touched an intraday low of Rs 996.7, representing a 2.02% drop. Over the past week, Natco Pharma has shown a positive return of 2.67%, but its year-to-date performance remains negative at -27.93%. Despite this recent decline, the company has demonstrated strong management efficiency with a high return on equity (ROE) of 15.57% and a healthy long-term growth rate in operating profit of 32.35% annually. The stock is trading at a discount compared to its peers, with a very attractive valuation indicated by a PEG ratio of 0.3.
In the broader market context, while Natco Pharma's short-term performance has been positive relative to the benchmark Sensex, which has only gained 0.97% over the past month, the stock's year-to-date decline of -27.93% contrasts sharply with the Sensex's increase of 6.46%. The stock's liquidity remains adequate for trading, with a delivery volume increase of 20.45% against the five-day average, suggesting rising investor participation. However, the recent price drop may reflect market corrections after previous gains, despite the company's solid fundamentals and high institutional holdings of 23.15%.
