Why is Astrazeneca Phar falling/rising?

As of 23-Jun, Astrazeneca Pharma India Ltd is experiencing a slight decline in its stock price, currently at 8,882.30, reflecting a decrease of 0.7 points or 0.01%. The stock has been on a downward trend, having lost 15.6% over the last six days, and it is currently trading below its 5-day and 20-day moving averages, despite being above the 50-day, 100-day, and 200-day moving averages. In terms of performance, the stock has shown strong returns over the longer term, with a year-to-date increase of 21.10% and a 39.86% rise over the past year, significantly outperforming the BSE 500 index. However, the recent consecutive falls indicate a shift in momentum, possibly influenced by a decline in institutional investor participation, which has decreased by 0.61% in the previous quarter.
In the broader market context, the stock's recent performance contrasts with the Sensex, which has seen a modest increase of 0.12% over the past week. While Astrazeneca Pharma has demonstrated high management efficiency and strong net profit growth, concerns about its high valuation and poor long-term growth prospects may be contributing to the current price decline. The stock's premium valuation relative to peers, coupled with falling institutional interest, suggests that despite its historical performance, there are underlying risks that could be affecting investor sentiment in the short term.
