Why is Nagarjuna Fert. falling/rising?

As of 07-Jul, Nagarjuna Fertilizers & Chemicals Ltd is experiencing a price increase, currently at 5.89, reflecting a rise of 0.28 or 4.99%. The stock has shown a strong performance today, outperforming its sector by 5.79% and has been gaining for the last two days, accumulating a total return of 7.09% during this period. However, despite this short-term gain, the company has a negative book value and a high debt-to-EBITDA ratio of 6.80 times, indicating weak long-term fundamental strength. The company has reported significant losses and negative net worth, which raises concerns for investors. Additionally, 37.41% of promoter shares are pledged, which could exert downward pressure on the stock in a falling market.
In the broader market context, the stock's recent performance contrasts with the benchmark, as it has gained 8.07% over the past week while the Sensex has declined by 0.20%. However, over the longer term, the stock has underperformed significantly, with a year-to-date return of -37.21% compared to the Sensex's gain of 6.79%. This consistent underperformance against the benchmark over the last three years, coupled with the company's ongoing financial struggles, suggests that while there may be short-term upward movement, the overall outlook remains challenging for Nagarjuna Fertilizers & Chemicals Ltd.
