Why is Marksans Pharma falling/rising?

As of 31-Jul, Marksans Pharma Ltd is experiencing a decline in its stock price, currently at 228.10, which reflects a decrease of 8.3 or 3.51%. Today's price summary indicates that the stock opened with a loss of 2.96% and has underperformed its sector by 2.02%. The stock has also seen a trend reversal, falling after two consecutive days of gains, and touched an intraday low of Rs 226.55. Over the past week, the stock has declined by 1.60%, and it has significantly underperformed in the last month with a drop of 11.76%. While the company has demonstrated high management efficiency and consistent returns over the last three years, it faces challenges such as poor long-term growth and an expensive valuation compared to its peers, contributing to the current downward movement.
In the broader market context, the Sensex has decreased by 1.22% over the past week, indicating that the market is also facing some headwinds, although Marksans Pharma's decline is more pronounced. The stock's year-to-date performance shows a significant drop of 23.00%, contrasting sharply with the Sensex's gain of 3.90%. This disparity highlights the stock's struggles relative to the overall market. Additionally, the falling investor participation, as evidenced by a 54.01% decrease in delivery volume against the 5-day average, suggests a lack of confidence among investors, further exacerbating the stock's decline.
