Why is Astrazeneca Phar falling/rising?

As of 26-Aug, Astrazeneca Pharma India Ltd's stock price is currently at Rs 8,069.80, reflecting a decline of Rs 197.2 or 2.39%. The stock has been underperforming recently, having fallen consecutively for the last two days, resulting in a total drop of 4.27% during this period. Today's trading saw the stock reach an intraday low of Rs 7,960, and it has been trading with higher volume closer to this low price. Additionally, the stock's performance over the past week shows a decline of 4.94%, and over the past month, it has decreased by 8.64%. Despite these short-term challenges, the company has demonstrated strong management efficiency with a high return on equity (ROE) of 20.34% and a low debt-to-equity ratio, which could support its long-term stability.
In the broader market context, Astrazeneca's recent performance contrasts with the benchmark Sensex, which has only declined by 1.05% over the past week. The stock's year-to-date return of 10.02% and a one-year return of 17.55% indicate that it has outperformed the benchmark over these longer periods, suggesting that the current decline may be more of a short-term fluctuation rather than a reflection of the company's overall health. The falling investor participation, as evidenced by a 17.97% drop in delivery volume, may also contribute to the stock's recent struggles, despite the positive financial results reported over the last three quarters.
