Why is T N Telecom. falling/rising?

As of 22-Jul, Tamil Nadu Telecommunications Ltd is experiencing a decline in its stock price, currently at 22.68, which reflects a decrease of 0.46 or 1.99%. The stock has been underperforming, having fallen consecutively for the last seven days, resulting in a total return decline of 13.14%. Additionally, the stock's performance today has underperformed its sector by 3.88%. Despite a strong long-term performance with a 132.14% return over the past year, the company is facing challenges such as a negative book value, weak long-term fundamental strength, and high debt levels, which are contributing to its recent price movement.
In the broader market context, the stock's short-term performance contrasts sharply with the benchmark, as it has declined by 9.57% over the past week while the Sensex has only decreased by 0.47%. This significant underperformance highlights the stock's current struggles despite its impressive long-term returns. The falling investor participation, indicated by a drastic drop in delivery volume, further exacerbates the situation, suggesting a lack of confidence among investors. Overall, while the stock has shown remarkable gains in the long term, its recent performance is marred by negative financial indicators and market sentiment.
