Why is Tata Tele. Mah. falling/rising?

As of 12-Sep, Tata Teleservices (Maharashtra) Ltd is experiencing a slight decline in its stock price, currently at 57.09, with a change of -0.04 (-0.07%). The stock has fallen after two consecutive days of gains and is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. In terms of performance, the stock has underperformed significantly over various periods, with a year-to-date decline of 24.37% and a one-year return of -38.61%. The company has a negative book value and weak long-term fundamentals, with net sales falling by 13.1% in the last quarter compared to the previous four-quarter average. Additionally, the company's high debt levels and poor growth metrics contribute to its status as a risky investment, which may deter potential investors.
In the broader market context, the stock's recent performance contrasts sharply with the benchmark, as the Sensex has gained 1.48% over the past week while Tata Teleservices has declined by 0.49%. This consistent underperformance against the benchmark over the last three years, coupled with a low stake from domestic mutual funds, suggests a lack of confidence in the company's future prospects. The rising investor participation indicated by a 106.02% increase in delivery volume may not be sufficient to offset the negative sentiment surrounding the stock, especially given its weak fundamentals and historical performance.
