In this segment from Thursday's Investor Beat, Motley Fool analyst David Hanson discusses why Discover (DFS +0.00%) 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 +0.30%)." David also talks about why this company should stand apart in investors' minds from the two big players in credit cards, Visa (V +1.00%) and MasterCard (MA +0.70%), and why Discover should almost be viewed more as a bank than a credit card company.
