With many banks reporting earnings last week, we decided to check Quant Ratings to see if there were any stocks worth investing in. Citigroup's earnings beat expectations on account of lower legal expenses. On the other hand, Goldman Sachs' earnings came in below expectations on account of higher legal expenses. However, Citigroup and Goldman Sachs both beat analyst revenue expectations, which is a bullish sign for bank stocks, and that should be the narrative through 2016.
