Why is Nagarjuna Fert. falling/rising?

As of 23-Jul, Nagarjuna Fertilizers & Chemicals Ltd is experiencing a decline in its stock price, currently at 6.25, which reflects a decrease of 0.16 or 2.5%. Today's price summary indicates that the stock has underperformed its sector by 2.46% and has fallen after two consecutive days of gains. Although the stock has shown a positive return of 1.63% over the past week and 15.96% over the past month, it has significantly underperformed over longer periods, with a year-to-date decline of 33.37% and a one-year drop of 46.63%. The company faces several challenges, including a negative book value, a high debt-to-EBITDA ratio of 6.80 times, and a negative net worth, which raises concerns about its long-term viability. Additionally, 37.41% of promoter shares are pledged, which can exert further downward pressure on the stock in a declining market.
In the broader market context, while the stock has outperformed the benchmark Sensex in the short term, it has consistently underperformed over the past three years, highlighting a troubling trend for investors. The Sensex has gained 5.87% year-to-date, contrasting sharply with Nagarjuna's significant losses. The company's financial instability, characterized by negative EBITDA and substantial losses, coupled with a lack of investor confidence reflected in the pledged shares, suggests that the stock's recent decline is driven by both internal weaknesses and broader market dynamics.
