Why is T N Telecom. falling/rising?

As of 25-Jul, Tamil Nadu Telecommunications Ltd is experiencing a decline in its stock price, currently at 21.36, reflecting a decrease of 0.43 or 1.97%. The stock has been underperforming, having fallen consecutively for the last 10 days, resulting in a total decline of 18.19% during this period. Despite a strong long-term performance with a 109.41% return over the past year, the stock's recent movement is negatively impacted by a negative book value and weak long-term fundamental strength, including stagnant net sales growth and a high debt-to-equity ratio. Furthermore, the stock's delivery volume has significantly decreased, indicating falling investor participation.
In the broader market context, the stock's short-term performance contrasts sharply with the benchmark, as it has underperformed the Sensex by 9.53% over the past week while the benchmark has only declined by 0.36%. Although the stock has shown remarkable returns over longer periods, the recent negative trends, including poor quarterly results and a risky trading profile compared to historical valuations, suggest that investors are cautious. This combination of factors contributes to the stock's current downward trajectory amidst a generally stable market environment.
