Better Buy: American Express Company vs. Square

Nearly two years have passed since I wrote my first article pitting credit card titan American Express (NYSE: AXP) against 21st-century payments processor Square (NYSE: SQ). I tagged AmEx for the win, as I felt at the time that it had the more durable and proven business model. Square was still experiencing growing pains.

Since then, much has changed for Square, if not necessarily for American Express. But has it changed enough to make it a winner in a rematch between the two stocks? Read on to find out.

Square's stock has been on an absolute tear this year, making it a real standout in the finance sector. On the back of a series of very strong quarterly results, it's risen by nearly 260% since January.
