Insights from Warren Buffett: CEO, Analysts, and Funfest.

American Express CEO Stephen Squeri reflects on the business and investing magic of legendary investor Warren Buffett, who has been a very long-term investor in AmEx. Buffett's approach is focused on the long term, allowing Squeri more "freedom" to test his ideas as CEO. Buffett's stake in AmEx has continued to increase as a result of stock buybacks, and he now owns more than 20% of the company. Squeri views his direct line to Buffett as a "privilege" and isn't concerned about the future of AmEx once Buffett steps aside as Berkshire Hathaway CEO.
