Rakuten Group Inc. shares jumped the most in more than four months on news that Mizuho Financial Group Inc. is in talks to acquire a stake in the e-commerce giant’s securities unit. 

Mizuho’s brokerage unit may buy a 20% stake in Rakuten Securities Inc. for about 80 billion yen ($554 million), people with knowledge of the matter said. An agreement could come by the end of the week, the Nikkei newspaper reported late Wednesday.
