Reasons why they suck:

$Goldman Sachs (GS.US)$ - Dodd Frank
$Citigroup (C.US)$ - What the hell is Citibank these days? They're still in business?
$Wells Fargo & Co (WFC.US)$ - Mortgage rates too low, Originations too high. Bloated overheat.
$Morgan Stanley (MS.US)$ - Sucks at trading. Hires anyone who didn't get job at Goldman.
