Well, Visa’s had a heck of a day. At the time I’m writing this, the price of Visa stock is up $20 per share (almost 9%) to $234. The cause for ebullience? Good earnings, and continued excellent prospects ahead. The company’s profitable margins continued to increase, going from 61% last year to 64% this year. Volumes are up 11%, year over year. The company is repurchasing an additional $5 billion worth of stock. Annual earnings per share growth still hovers around the 15% mark. The China State Council approved plans to open banking clearinghouses, and successful penetration of the Chinese market could prove highly lucrative to Visa shareholders.
