In this video, Motley Fool analysts David Hanson and Matt Koppenheffer talk about the Dodd-Frank banking stress test results from last week and which banks nearly didn't make the grade. While only one bank failed, Goldman Sachs (GS 1.78%) and Morgan Stanley (MS 1.82%) reported the lowest passing stressed minimum ratios, the key metric regulators look at when deciding how healthy a bank would be in a crisis. Matt and David tell us whether investors should be concerned and why the investment portfolios of Goldman Sachs and Morgan Stanley make them more vulnerable during a crash.
