Why is Astrazeneca Phar falling/rising?

As of 27-Jun, Astrazeneca Pharma India Ltd's stock price is rising, currently at 8,904.10, reflecting an increase of 141.6 or 1.62%. The stock has shown strong performance today, outperforming its sector by 0.74% and reaching an intraday high of Rs 8956.15, which is a 2.21% increase. Over the past week, the stock has gained 0.24%, while in the last month, it has risen by 12.83%. The company has demonstrated high management efficiency with a return on equity (ROE) of 19.06% and a low debt-to-equity ratio. Positive financial results, including an 88.82% growth in net profit and the highest quarterly net sales recorded at Rs 480.48 crore, have contributed to the stock's upward movement. However, there are concerns regarding poor long-term growth, as the operating profit has only grown at an annual rate of 15.95% over the last five years, and institutional investor participation has decreased.
Broader market context indicates that while Astrazeneca Pharma has performed well, its short-term return of 0.24% over the past week is significantly lower than the benchmark Sensex, which has increased by 2.00% in the same period. Despite the stock's strong performance over the longer term, with a 39.78% return over the past year compared to the Sensex's 6.08%, the recent decline in institutional investor participation and the stock's premium valuation relative to peers could pose risks to its continued growth.
