Over the past week, the stock has dropped by 4.29%, and it has shown a significant decline of 12.02% over the past month.

In the broader market context, the Sensex has only decreased by 0.77% over the past week and 3.26% over the past month, indicating that Tata Teleservices' decline is more pronounced than the overall market trend. The stock's performance has been particularly poor over the last three years, with a return of -48.30% compared to the benchmark's gain of 38.23%. This consistent underperformance, coupled with a high debt-to-equity ratio and low domestic mutual fund investment, suggests that investor confidence in the company is waning, contributing to its current price decline.
