Why is Bihar Sponge falling/rising?

As of 18-Jul, Bihar Sponge Iron Ltd's stock price is currently at 17.80, reflecting a decline of 0.43, or 2.36%. The stock has been underperforming recently, having fallen for the last two days with a total drop of 5.12%. Despite this short-term decline, the stock has shown strong performance over longer periods, with a 19.95% increase in the last month and a remarkable 1773.68% rise over the past five years. However, the company faces challenges, including a negative book value and high debt levels, which contribute to its weak long-term fundamental strength. Additionally, the stock's performance has been impacted by a significant drop in delivery volume, which fell by 30.8% compared to the five-day average.
In the broader market context, Bihar Sponge Iron has outperformed the Sensex in various time frames, including a 12.30% return over the past year compared to the index's 0.51%. However, the stock's recent performance has been hindered by its negative EBITDA and a high percentage of pledged promoter shares, which can exert downward pressure in a falling market. While the stock has shown resilience in the long term, the current market conditions and the company's financial challenges have led to its recent decline.
