Why is Astrazeneca Phar falling/rising?

As of 21-Aug, Astrazeneca Pharma India Ltd is experiencing a decline in its stock price, currently at 8,385.00, which reflects a decrease of 96.15 points or 1.13%. The stock has underperformed its sector by 1.59% today and has been on a consecutive downward trend for the last two days, resulting in a total decline of 1.23% during this period. Despite showing strong performance over the longer term with a year-to-date increase of 14.32% and a substantial 26.72% rise over the past year, the stock has recently faced challenges, including a significant drop in delivery volume by 84.38% compared to the five-day average. The stock is currently trading above its 200-day moving average but below its shorter-term moving averages, indicating mixed signals in its price momentum.
In the broader market context, Astrazeneca's recent performance contrasts sharply with the Sensex, which has gained 1.74% over the past week and is up 4.94% year-to-date. This divergence suggests that while the overall market is experiencing upward momentum, Astrazeneca is struggling to maintain its position. Despite the company's strong fundamentals, including high management efficiency and consistent positive results over the last three quarters, the recent decline in investor participation and short-term underperformance against the benchmark may be contributing to the stock's current downward trajectory.
