When it comes to safe, "steady as she goes" banks, Citigroup (NYSE:C) is certainly no Wells Fargo (NYSE:WFC). While the latter took its lumps during the financial meltdown, its more conservative style helped it avoid the massive losses that Citigroup faced. That's also why Wells Fargo remains a more favored bank for most investors today.

But is it really as simple as it seems with Citi? I'm not so sure. In fact, for investors that have a bit more of a taste for risk, there may be a very real opportunity in Citigroup's stock as the bank looks to turn itself around.
