Why is Parmax Pharma falling/rising?

As of 20-Oct, Parmax Pharma Ltd is experiencing a decline in its stock price, currently at Rs 31.16, which represents a decrease of Rs 3.28 or 9.52%. The stock has underperformed significantly today, with a performance that is 10.2% lower than its sector. It has also touched an intraday low of Rs 31.01, indicating high volatility with a range of Rs 3.29. Over the past week, the stock has decreased by 2.01%, and it has shown a substantial decline of 29.58% year-to-date. The company's negative book value and weak long-term fundamentals, including a poor EBIT to interest ratio and declining net sales, contribute to its current downward trajectory.
In the broader market context, the Sensex has increased by 2.47% over the past week, highlighting the stark contrast between the stock's performance and that of the benchmark. Parmax Pharma has consistently underperformed against the benchmark over the last three years, with a return of -23.81% in the past year compared to the Sensex's 3.86% gain. This consistent underperformance, coupled with the company's weak financial indicators, suggests that investor sentiment remains negative, further exacerbating the stock's decline.
