Why is Vindhya Telelink falling/rising?

As of 22-Sep, Vindhya Telelinks Ltd is experiencing a decline in its stock price, currently at 1,501.35, reflecting a decrease of 16.5 points or 1.09%. The stock has underperformed its sector today by 0.28% and has fallen after three consecutive days of gains, touching an intraday low of Rs 1,485, which is a 2.16% drop. Over the past week, the stock has decreased by 0.71%, and its year-to-date performance shows a significant decline of 20.48%. Despite a very attractive valuation indicated by a ROCE of 4.6 and trading at a discount compared to peers, the stock has generated a return of -35.37% over the past year, with profits falling by 8.4%, contributing to its recent price movement.
In the broader market context, the stock's performance contrasts sharply with the Sensex, which has gained 0.46% over the past week and 5.15% year-to-date. This underperformance is further highlighted by the stock's negative returns over the last three years, one year, and three months, indicating below-par performance both in the long term and near term. The stock's liquidity remains adequate for trading, but the overall sentiment is dampened by flat operating results and poor long-term growth prospects, as evidenced by an annual operating profit growth rate of only 3.24% over the last five years.
