In this segment from Thursday's Investor Beat, Motley Fool analyst David Hanson discusses why Discover (DFS) 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 1.15%)." David also talks about why this company should stand apart in investors' minds from the two big players in credit cards, Visa (V 0.90%) and MasterCard (MA 0.90%), and why Discover should almost be viewed more as a bank than a credit card company.
