Why is M T N L falling/rising?

As of 21-Aug, Mahanagar Telephone Nigam Ltd's stock is currently priced at 45.90, reflecting an increase of 1.9 or 4.32%. The stock has been on an upward trend, gaining for the last four days with a total return of 8.43% over the past week. Despite this recent positive movement, the company has shown poor long-term growth, with net sales declining at an annual rate of -17.94% and a negative book value indicating weak fundamental strength. Additionally, the company has reported negative results for the last two consecutive quarters, which has contributed to a risky trading environment, as evidenced by a significant drop of -30.79% in stock value over the past year.
In the broader market context, Mahanagar Telephone Nigam Ltd has outperformed the Sensex by 4.59% today, while the benchmark index has only increased by 1.74% over the past week. However, the stock has underperformed the market significantly over the last year, with a return of -30.79% compared to the Sensex's modest gain of 1.35%. This stark contrast highlights the challenges the company faces, including high debt levels and a lack of confidence from domestic mutual funds, which hold no stake in the company. Overall, while there is a short-term positive movement in the stock price, the long-term outlook remains concerning due to fundamental weaknesses.
