Why is Vodafone Idea falling/rising?

As of 19-Sep, Vodafone Idea Ltd. is experiencing a rise in its stock price, currently at 8.41, reflecting an increase of 0.56 or 7.13%. The stock has outperformed its sector by 5.68% today and has shown a consecutive gain over the last two days, with an overall return of 8.1% during this period. Additionally, the stock has performed well over the past week and month, with returns of 9.65% and 27.62%, respectively. However, it is important to note that the stock has a negative book value and a high debt-to-EBITDA ratio of 9.60 times, indicating weak long-term fundamental strength and low profitability, which could pose risks to its future performance.
In the broader market context, Vodafone Idea's recent performance contrasts sharply with the benchmark, as it has significantly outperformed the Sensex, which only gained 0.88% over the same week. Despite the positive short-term movements, the stock has underperformed over the past year, with a decline of 18.98%, compared to a slight negative return of 0.67% for the Sensex. The stock's liquidity remains adequate for trading, but a notable decline in delivery volume by 60.92% against the 5-day average suggests a decrease in investor participation, which could impact future price movements.
