Why is Marksans Pharma falling/rising?

As of 12-Aug, Marksans Pharma Ltd is experiencing a decline in its stock price, currently at Rs 186.80, which represents a decrease of Rs 24.2 or 11.47%. The stock has been underperforming significantly, having fallen by 17.38% over the past week and 26.63% over the past month. Today, the stock has shown high volatility, trading within a wide range of Rs 35.25, with an intraday low of Rs 180.1, reflecting a substantial drop of 14.64%. Despite a high management efficiency indicated by a return on equity (ROE) of 17.66% and low debt levels, the company has reported poor long-term growth, with operating profit increasing at a mere 2.87% annually over the last five years. Additionally, negative quarterly results and a low return on capital employed (ROCE) have contributed to the stock's downward trend.
In the broader market context, the Sensex has only decreased by 0.59% over the past week, indicating that Marksans Pharma's decline is more pronounced than the overall market. The stock's performance has been notably weaker compared to the benchmark, with a year-to-date return of -36.95% against the Sensex's positive return of 2.68%. This stark contrast highlights the challenges faced by Marksans Pharma, particularly in light of its recent negative financial results and high valuation concerns, which have led to a lack of investor confidence despite some positive factors such as rising institutional holdings.
