Why is Vodafone Idea falling/rising?

As of 29-Jul, Vodafone Idea Ltd. has experienced a slight increase in its stock price, currently at 7.20, reflecting a change of 0.07 or 0.98% upward. Despite this recent uptick, the stock has shown a negative performance trend, with a decline of 2.44% over the past week and a significant drop of 55.17% over the last year. Today's price summary indicates that the stock has gained after three consecutive days of decline, although it underperformed its sector by 0.31%. The stock's delivery volume has increased, suggesting rising investor participation, but it remains under pressure due to its negative book value and high debt-to-EBITDA ratio of 9.60 times, which raises concerns about its long-term sustainability.
In the broader market context, Vodafone Idea's recent performance contrasts with the benchmark Sensex, which has shown a decline of only 1.03% over the past week and a positive return of 4.09% year-to-date. This indicates that while Vodafone Idea is experiencing a minor rebound, it is still lagging behind the overall market performance. The company's high institutional holdings at 59.13% suggest that more sophisticated investors are involved, yet the stock's weak long-term fundamentals, negative operating profits, and the necessity for fresh capital or profitability to sustain operations contribute to its overall riskiness and underperformance compared to the broader market.
