Why is Coal India falling/rising?

As of 01-Sep, Coal India Ltd. is currently priced at 377.65, reflecting an increase of 2.9 or 0.77%. The stock has shown a positive trend recently, gaining for the last three days with a total return of 1.31%. However, it has underperformed its sector by 0.55% today and has a narrow trading range of Rs 3.4. Over the past week, the stock has declined by 0.62%, while it has performed better over the past month with a return of 1.41%. Despite a significant annual decline of 28.07%, the company maintains strong long-term fundamentals, including a high return on equity (ROE) of 40.88% and a low debt-to-equity ratio. The stock's attractive valuation, with a price-to-book value of 2.3, and a high dividend yield of 8.57% may also support its price stability.
In the broader market context, Coal India has underperformed the benchmark Sensex over the past year, which has seen a decline of only 2.43%. The stock's recent performance contrasts with the market's overall trend, as it has faced a more significant drop in value. Additionally, the falling investor participation, indicated by a 23.4% decrease in delivery volume compared to the five-day average, may contribute to the stock's volatility. Despite these challenges, the company's high institutional holdings at 30.93% suggest that larger investors continue to have confidence in its long-term prospects, which could provide some support against further declines.
