Why is NMDC falling/rising?

As of 04-Sep, NMDC Ltd is experiencing a decline in its stock price, currently at 73.39, which reflects a decrease of 0.89 or 1.2%. Today's price summary indicates that the stock has underperformed its sector by 1.05% and has fallen after four consecutive days of gains. Despite this recent downturn, NMDC has shown strong performance over the past week, with a return of 6.72%, and has outperformed the benchmark Sensex, which only gained 0.80%. The stock is trading above its moving averages, indicating a generally positive trend, and has seen a significant increase in investor participation, with delivery volume rising by 40.38% against the five-day average. The company also boasts a high dividend yield of 5.12%, which may attract income-focused investors.
In the broader market context, while NMDC has shown impressive returns over longer periods, including an 11.28% gain year-to-date and a substantial 82.44% increase over three years, its recent performance contrasts with the Sensex's modest 3.30% gain year-to-date. The stock's strong fundamentals, including a healthy return on equity and low debt-to-equity ratio, support its long-term growth potential, but the recent flat results and a low debtors turnover ratio may raise concerns among investors. Additionally, high institutional holdings suggest confidence in the company's prospects, yet the stock's current premium valuation compared to peers could be a factor in its recent price decline.
