30 Jun 2017 Warren Buffett just made a quick $12 billion on a clever Bank of America investment ( Portfolio )

Buffett's Berkshire Hathaway said Friday it will exercise warrants in Bank of America that will allow it to acquire 700 million common shares in the bank at an exercise price of just $7.14 each, or about $5 billion.

Bank of America shares closed Thursday at $24.32 a share, making that stake actually worth more than $17 billion. So it's a quick $12 billion paper profit for the Oracle of Omaha.
