Why is NMDC Steel falling/rising?

As of 12-Sep, NMDC Steel Ltd is experiencing a price increase, currently at 46.31, reflecting a rise of 0.73 or 1.6%. The stock has shown strong performance recently, gaining 10.98% over the last six days and outperforming its sector by 1.63% today. Additionally, NMDC Steel has reported positive results, including an 18.57% growth in net sales and significant increases in profit before tax and operating profit ratios. However, despite these positive indicators, the company faces challenges such as weak long-term fundamental strength, with a return on capital employed of 0% and a high debt to EBITDA ratio, which may raise concerns among investors.
In the broader market context, NMDC Steel's one-week return of +8.91% significantly outpaces the Sensex's return of +1.48%, indicating strong short-term momentum relative to the benchmark. While the stock has shown positive short-term performance, it has a negative return of -12.01% over the past year, contrasting with the Sensex's decline of only -1.28%. This discrepancy highlights the stock's volatility and the potential risks associated with its long-term growth prospects, despite recent gains and high institutional interest.
