Why is Mankind Pharma falling/rising?

As of 23-Sep, Mankind Pharma Ltd's stock price is currently at 2,560.00, reflecting a decrease of 36.2 points or 1.39%. The stock has been underperforming recently, having fallen consecutively for the last two days, resulting in a total decline of 3.8% during this period. Additionally, the stock's performance over the past week shows a slight decline of 0.32%, while it has dropped 1.92% over the past month. Despite having a high management efficiency indicated by a return on equity of 17.21% and a low debt-to-equity ratio, the stock's recent movement is negatively impacted by a significant drop in investor participation, with delivery volume decreasing by 26.21% compared to the five-day average.
In the broader market context, Mankind Pharma's performance has been slightly better than the benchmark Sensex over the past week, where the Sensex also experienced a minor decline of 0.34%. However, the stock has significantly underperformed the Sensex year-to-date, with a decline of 11.01% compared to the benchmark's increase of 5.07%. This underperformance, coupled with a lack of positive momentum in the stock's trading activity and a recent trend of falling prices, suggests that investor sentiment may be cautious, despite the company's strong fundamentals and institutional support.
