Why is T N Telecom. falling/rising?

The stock has been underperforming significantly, having lost 34.31% over the last 21 days and is currently down 9.53% over the past week. Despite its strong performance year-to-date with a gain of 35.78%, the stock's recent trajectory has been negative, with a notable underperformance against its sector by 0.97%. Additionally, the stock's delivery volume has decreased sharply by 75.68% compared to the 5-day average, indicating falling investor participation, which may further contribute to the downward pressure on the stock price.
In the broader market context, while the Sensex has only declined by 0.59% over the past week, Tamil Nadu Telecommunications Ltd's performance has been markedly worse, suggesting that specific company-related issues are influencing its stock price more than general market trends. The stock's performance over the last month shows a significant drop of 35.62%, contrasting sharply with the Sensex's modest decline of 2.75%. This disparity highlights the challenges faced by the company, particularly in the short term, despite its long-term growth reflected in the 3-year and 5-year returns.
