The following video is part of our "Motley Fool Conversations" series, in which senior analyst Anand Chokkavelu, CFA, discusses topics across the investing world. There's a whole lot of risk in America's largest banks. But in at least one way, Citigroup stands out from Bank of America, JPMorgan, Goldman Sachs, and the rest. It's the most internationally focused, with only 37% of its sales and less than 30% of its profits coming from North America. With significant operations in Asia, Europe, and Latin America, Citi's global diversity can be a very good thing, but depending on your regional outlook, that could also have Citi chasing the next financial crisis. Anand explains in the video below.
