Why is Vodafone Idea Fluctuating So Much

Vodafone Has Debt of about 1.05 lakh crores and google is only taking about 5 % stake it is still in debt why then it is fluctuating by 30%

It’s just reaction to the news of Google’s interest in buying stake in Idea which investors probably see as good sign for the company. How does company benefit from it will be known in future but this jump is just reaction to that news.
