Despite anxiety in the financial markets, investors flocked to buy stock in credit card giant Visa.
On Tuesday, the company completed the biggest initial public stock offering in U.S. history. At $44 a share, the IPO raised nearly $18 billion.
When the stock began trading Wednesday on the New York Stock Exchange, the price jumped nearly 50 percent higher.
Despite the slowing economy and the turmoil in the markets, the banks that owned the credit card processing company had good reason to take the plunge now.
