The financial sector, as a whole, appears to be on the rise. Since December, a combination of easing of concerns about Europe, strong earnings reports, and successful stress tests have helped the sector rebound from its previously moribund state. Since November 24 of last year, the Financial Select Sector SPDR (XLF), an ETF that tracks the financial sector, has gained over 30 percent, showing the sector as a whole has been on the rise.

Given the potential that the financial sector is rebounding, some investors may be seeking out cheap options to invest in the financial sector. While many will simply cull over the well known investment banks and hedge funds, there are also several small cap financial stocks that offer attractive valuations. The following stocks have P/E ratios under 15, meaning that they’re coming at a cheap price based on their earnings, as well as showing at least a 15 percent jump in share price over the last six months. What’s more, these stocks tend to be a favorite among those analysts reviewing them.
