Why is Railtel Corpn. falling/rising?

As of 26-Aug, Railtel Corporation of India Ltd is experiencing a decline in its stock price, currently at Rs 344.00, which reflects a decrease of Rs 9.05 or 2.56%. The stock has been on a downward trend, having fallen consecutively for the last three days, resulting in a total decline of 4.85% during this period. Additionally, the stock's performance over the past week and month shows a decrease of 4.20% and 12.68%, respectively. The company reported flat results for the quarter ending June 25, with net sales and profits falling significantly compared to previous averages, contributing to investor concerns. Although the company has a low debt-to-equity ratio and has seen a healthy long-term growth in net sales, the recent financial results and a high price-to-book value ratio suggest that the stock may be overvalued, leading to a negative sentiment among investors.
In the broader market context, Railtel's performance has underperformed relative to the benchmark, with a one-year return of -31.64% compared to the BSE500's decline of only -3.87%. The telecommunications equipment sector has also faced challenges, with a sector-wide decline of 2.81%. Furthermore, there has been a notable decrease in investor participation, with delivery volume falling by nearly 49% against the five-day average, indicating reduced interest in the stock. Despite some positive factors, such as increased institutional investor participation, the overall market sentiment and recent financial performance have contributed to the stock's decline.
