Why is Railtel Corpn. falling/rising?

As of 05-Aug, Railtel Corporation of India Ltd is experiencing a decline in its stock price, currently at 366.45, reflecting a decrease of 1.75 or 0.48%. The stock has shown a negative performance trend, with a 1-week return of -4.64% and a 1-month return of -12.47%. Today's price summary indicates that the stock is performing inline with its sector, although it is trading higher than its 100-day moving average but lower than its 5-day, 20-day, 50-day, and 200-day moving averages. Additionally, there has been a notable decrease in investor participation, with delivery volume falling by 6.18% against the 5-day average. Despite a low debt-to-equity ratio and healthy long-term growth in net sales, the company reported flat results in its latest quarterly earnings, with significant declines in net sales, profit before tax, and profit after tax compared to previous quarters.
In the broader market context, Railtel's stock has underperformed relative to the benchmark, with a 1-year return of -22.02% compared to the BSE500's positive return of 0.50%. This underperformance is further highlighted by the stock's significant decline over the past year, despite a rise in profits, indicating a very expensive valuation with a high price-to-book value ratio. The increasing participation of institutional investors, who have raised their stake by 0.67%, may provide some support; however, the overall negative sentiment surrounding the company's recent financial results and its inability to keep pace with market performance contribute to the stock's downward trajectory.
