Why is NMDC Steel falling/rising?

As of 08-Sep, NMDC Steel Ltd's stock price is currently at 43.30, reflecting an increase of 0.78 or 1.83%. The stock has shown strong performance recently, gaining 3.76% over the last two days and outperforming its sector by 0.54% today. Additionally, the stock has risen significantly over the past week and month, with returns of 14.07% and 21.42%, respectively. The company has reported positive results, including an 18.57% growth in net sales and a substantial increase in profit before tax, which has contributed to the recent upward movement in stock price. However, it is important to note that the stock has a weak long-term fundamental strength, evidenced by a 0% average return on capital employed and a high debt-to-EBITDA ratio, which may pose risks for future performance.
In the broader market context, NMDC Steel's recent gains are notable compared to the Sensex, which has only increased by 0.53% over the past week and 1.16% over the past month. Despite the stock's impressive short-term performance, it has underperformed the market over the last year, with a decline of 19.13% compared to the Sensex's slight drop of 0.49%. This contrast highlights the stock's volatility and the potential risks associated with its long-term outlook, despite the positive short-term indicators and strong institutional holdings that suggest some level of confidence among more knowledgeable investors.
