Citigroup's market cap is 140 billion dollars, near it's 2007 high. Unlike other banks, citigroup issued billions of additional shares and their current outstanding shares are at 28 billion! It would be illogical to think at the current amount of citi would increase to it's pre-crash levels, at 50 dollar's a share it's value would shoot beyond 1 trillion. So citigroup would be required to do a reverse split correct? How does a reverse split affect the future of a stock? How will their current predicament affect the future of their stock ?
