Why is Railtel Corpn. falling/rising?

As of 22-Sep, Railtel Corporation of India Ltd is experiencing a decline in its stock price, currently at Rs 387.50, which reflects a decrease of Rs 6.35 or 1.61%. The stock has underperformed its sector by 1.7% today and has been on a downward trend for the last three days, accumulating a total decline of 3.28%. Additionally, the stock's performance over the past week shows a decrease of 3.04%, while it has gained 9.31% over the past month. Despite these recent challenges, the company has a low debt-to-equity ratio and has seen healthy long-term growth with net sales increasing at an annual rate of 27.33%. Furthermore, there has been an increase in institutional investor participation, which may provide some support for the stock despite its current struggles.
Broader Market Context: In comparison to the benchmark Sensex, Railtel's short-term performance has been notably weaker, with the stock declining 3.04% over the past week while the Sensex has increased by 0.46%. This underperformance highlights the stock's recent difficulties in attracting investor interest, as evidenced by a significant drop in delivery volume, which fell by 67.87% against the five-day average. While the stock remains liquid enough for trading, the broader market context suggests that Railtel is facing headwinds that are contributing to its current price decline.
