In the following video, Motley Fool contributing writer John Reeves takes a look at the big Wall Street financial institutions, to see how they have performed over the past five years since the financial crisis. He tells investors that while JPMorgan (NYSE:JPM) and Wells Fargo (NYSE:WFC) have still managed strong positive returns over that five-year period, most of the major Wall Street financial institutions are in the red since 2008. He then goes on to list many of the practices that led to the financial crisis that are still visible today in these firms, and tells us why he is leery of these stocks in the long term at the moment.
