Why is Oxygenta Pharma falling/rising?

As of 18-Aug, Oxygenta Pharmaceutical Ltd is experiencing a decline in its stock price, currently at Rs 87.10, reflecting a decrease of Rs 1.4 or 1.58%. The stock has underperformed its sector by 1.81% today and has been on a consecutive downward trend for the last four days, resulting in a significant drop of 12.9% over the past week. Despite touching an intraday high of Rs 93.2, it also reached a low of Rs 84.4, indicating a wide trading range of Rs 8.8. The stock's performance over the past month shows a decline of 17.52%, while it has still managed to deliver impressive returns of 132.27% over the past year. However, the company faces challenges such as a negative book value, high debt levels, and poor long-term growth indicators, which contribute to its current price movement.
In the broader market context, the Sensex has shown a slight increase of 0.83% over the past week, contrasting with Oxygenta's significant decline. While the stock has outperformed the market over the past year, its recent performance has been lackluster compared to the benchmark, which has generated negative returns of -1.14% in the same timeframe. The rising promoter confidence, with a 6.8% increase in stake, suggests some positive sentiment about the company's future; however, the negative EBITDA and flat results in the latest quarter raise concerns about its long-term viability. Overall, the combination of short-term underperformance and fundamental weaknesses appears to be driving the stock's current downward trend.
