Why is Astrazeneca Phar falling/rising?

As of 15-Sep, Astrazeneca Pharma India Ltd is experiencing a decline in its stock price, currently at 8,985.00, reflecting a decrease of 15.0 points or 0.17%. The stock has been under pressure, having fallen consecutively for the last two days, resulting in a total decline of 1.04% during this period. Despite outperforming its sector by 0.28% today, the stock's delivery volume has decreased significantly, falling by 37.58% against the five-day average, indicating reduced investor participation. Over the past month, the stock has shown a positive return of 8.37%, and it has performed well over the year with a 32.31% increase, although it has lagged behind the benchmark Sensex in the short term.
In the broader market context, Astrazeneca's recent performance contrasts with the Sensex, which has gained 1.24% over the past week and 1.47% over the past month. While the company has demonstrated strong management efficiency with a high return on equity and low debt levels, the recent decline in stock price may be attributed to the falling investor participation and the stock's underperformance in the short term compared to the benchmark. Nonetheless, the company has consistently delivered positive financial results over the last three quarters, which supports its long-term growth potential despite the current price movement.
