Why is T N Telecom. falling/rising?

As of 17-Jul, Tamil Nadu Telecommunications Ltd is experiencing a decline in its stock price, currently at 24.09, reflecting a decrease of 0.49 or 1.99%. The stock has underperformed its sector by 2.5% today and has been on a downward trend for the last four days, accumulating a total loss of 7.74% during this period. Despite a remarkable long-term performance with a 146.57% return over the past year, the company is facing challenges such as a negative book value and weak long-term fundamental strength, which are contributing to its current price movement. Additionally, the stock's delivery volume has significantly decreased, indicating falling investor participation, which further exacerbates the downward pressure on the stock.
In the broader market context, the stock's recent performance contrasts with the benchmark, as it has declined by 3.14% over the past week while the Sensex has only fallen by 1.12%. Although the stock has shown impressive returns over longer periods, such as a 236.45% increase over three years, the recent flat results and negative EBITDA signal underlying issues that investors may be wary of. The high debt levels and poor growth in net sales and operating profit over the last five years also contribute to the stock's risk profile, making it less attractive in the current market environment.
