In this segment from Thursday's Investor Beat, Motley Fool analyst David Hanson discusses why Discover (DFS 0.33%) should stand in its own right as a strong performing investment, rather than continuing to hold the stigma among investors as "the poor man's American Express (AXP 0.09%)." David also talks about why this company should stand apart in investors' minds from the two big players in credit cards, Visa (V -1.70%) and MasterCard (MA -1.20%), and why Discover should almost be viewed more as a bank than a credit card company.
