At least American Express still has Warren Buffett's confidence
American Express is spending money in hopes to make money. They are looking to attract more cardholders and retail partners after having a disappointing 2015. Amex CEO, Ken Chenault, told shareholders the company is doing this with a great sense urgency. Despite losing its largest partnership in Costco wholesale last year, Warren Buffett says he's happy to own the stock—and that he feels okay with it.
