Why is Nagarjuna Fert. falling/rising?

As of 18-Aug, Nagarjuna Fertilizers & Chemicals Ltd is experiencing a decline in its stock price, currently at 5.95, down by 0.05 or 0.83%. The stock has underperformed its sector by 2.11% today, and while it has shown a positive return of 3.66% over the past week, it has a negative return of 4.03% over the past month and a significant decline of 36.57% year-to-date. The company's financial health is concerning, as it has a negative book value and a high debt-to-EBITDA ratio of 6.80 times, indicating a weak ability to service its debt. Additionally, the company has reported losses, with a negative net worth and a drastic drop in profit after tax of 100.3% in the latest quarter. The stock is also trading at risky levels compared to its historical valuations, contributing to its recent downward movement.
In the broader market context, the stock's performance has been notably worse than the benchmark, with a year-to-date decline of 36.57% compared to a 4.01% gain in the market. Over the past year, while the BSE500 index has seen a slight negative return of 1.14%, Nagarjuna Fertilizers has plummeted by 43.12%. The company's high percentage of pledged promoter shares, at 37.41%, adds further downward pressure in a falling market, making it a risky investment. Overall, the combination of poor financial results, high debt levels, and significant underperformance relative to the market has led to the current decline in the stock price.
