Why is Astrazeneca Phar falling/rising?

As of 22-Aug, Astrazeneca Pharma India Ltd's stock price is currently at 8,430.00, reflecting an increase of 45.0 points or 0.54%. The stock has shown a trend reversal, gaining after two consecutive days of decline. Despite this recent uptick, the stock's performance over the past week has been slightly negative, with a decrease of 0.16%, and a more significant drop of 6.62% over the past month. However, the company has demonstrated strong financial health, with a high return on equity of 20.34%, a low debt-to-equity ratio, and positive results in the last three quarters, including a notable growth in pre-tax profit. The stock has consistently outperformed the BSE500 over the last three years, generating a return of 25.59% in the past year.
In the broader market context, the Sensex has increased by 0.88% over the past week, indicating that Astrazeneca's short-term performance is lagging behind the benchmark. While the stock has maintained a strong year-to-date return of 14.93%, its recent decline in delivery volume, which fell by 85.42% against the five-day average, suggests a decrease in investor participation. This decline in trading activity may contribute to the stock's volatility despite its solid fundamentals and historical performance. Overall, while Astrazeneca Pharma India Ltd has shown resilience and strong returns over the long term, its short-term movements are influenced by market dynamics and investor sentiment.
