Why is M T N L falling/rising?

As of 19-Sep, Mahanagar Telephone Nigam Ltd's stock price is currently at 45.12, reflecting a decrease of 0.09 or 0.2%. The stock has underperformed its sector by 1.65% today and has been on a downward trend for the last two days, accumulating a total decline of 0.27%. Over the past week, the stock has shown a modest gain of 2.64%, but it has significantly lagged behind the benchmark Sensex, which rose by 0.88%. The company has reported negative results for the last two consecutive quarters, with net sales and profit after tax both declining by 40.03%. Additionally, the company has a negative book value and a high debt-to-equity ratio, indicating weak long-term fundamentals and high risk, which likely contribute to the stock's recent price movement.
Broader market context shows that while the stock has gained 3.37% over the past month, it has still underperformed the Sensex, which increased by 1.20% during the same period. The stock's year-to-date performance is particularly concerning, with a decline of 10.42% compared to the Sensex's gain of 5.74%. The falling investor participation, as evidenced by a 9.76% decrease in delivery volume, further suggests a lack of confidence among investors. Overall, despite some short-term gains, the combination of negative financial results, high debt, and poor long-term growth prospects has led to a decline in the stock's price.
