Why is T N Telecom. falling/rising?

As of 18-Jul, Tamil Nadu Telecommunications Ltd is experiencing a decline in its stock price, currently at 23.61, reflecting a decrease of 0.48 or 1.99%. The stock has been underperforming, having fallen consecutively for the last five days, resulting in a total drop of 9.57% over that period. Despite a strong long-term performance with a 137.05% return over the past year, the stock is currently facing challenges, including a negative book value and weak long-term fundamental strength. The company's financials show poor growth, with net sales growing at an annual rate of 0% and a high debt-to-equity ratio, contributing to its recent price decline.
In the broader market context, the stock's recent performance contrasts sharply with the benchmark Sensex, which has only declined by 0.90% over the same one-week period. While Tamil Nadu Telecommunications Ltd has outperformed the benchmark in the long term, the current underperformance and falling investor participation, evidenced by an 87.89% drop in delivery volume, indicate a lack of confidence among investors. The stock's liquidity remains adequate for trading, but the combination of negative earnings and high debt levels raises concerns about its future performance, leading to its current downward trend.
