Why is M T N L falling/rising?

As of 17-Sep, Mahanagar Telephone Nigam Ltd's stock price is currently at 45.24, reflecting an increase of 0.26 or 0.58%. The stock has been gaining for the last three days, with a total return of 2.91% during this period. However, despite this short-term positive movement, the stock has underperformed over the longer term, with a year-to-date decline of 10.18% and a one-year drop of 19.21%. The company's financial health is concerning, as it has a negative book value and has reported negative results for the last two consecutive quarters, with net sales and profit after tax both declining significantly. Additionally, the company has a high debt-to-equity ratio, indicating financial instability, which may deter investor confidence.
Broader market context shows that while the stock has outperformed its sector by 0.7% today, it still lags behind the benchmark Sensex, which has risen by 1.56% over the past week and 2.60% over the past month. The stock's liquidity appears adequate, but a decrease in delivery volume suggests falling investor participation, which could further pressure the stock price. Overall, despite recent gains, the underlying financial weaknesses and the stock's historical performance relative to the market indicate a challenging environment for Mahanagar Telephone Nigam Ltd.
