Financial sector stocks have slid back along with the broader markets over the past month, but the auspicious start to this earnings season has helped bank picks and financial sector exchange traded funds regain some of their lost strength.

Companies like JPMorgan (NYSE: JPM), Wells Fargo (NYSE: WFC), Goldman Sachs (NYSE: GS) and U.S. Bancorp (NYSE: USB) are just some banks that have topped analyst earnings, writes Don Dion for TheStreet. [Bank Earnings Disappoint Bullish ETF Options Traders]

Investors seeking to express their opinion on the sector may consider financial ETF optionsl like the iShares Dow Jones U.S. Financial Sector Index Fund (NYSEArca: IYF) or Financial Select Sector SPDR (NYSEArca XLF).

The iShares fund also favors the banks and financial services sub-sectors, whereas the SPDR ETF holds a higher weighting in insurance companies.

On a cost basis, XLF is cheaper at 0.18% compared to IYF’s expense ratio of 0.47%.

For those looking for small, regional names, SPDR S&P Regional Banking ETF (NYSEArca: KRE) and iShares Dow Jones U.S. Regional Bank Index Fund (NYSEArca: IAT) fulfill that role. KRE has an expense ratio of 0.35% and IAT has an expense ratio of 0.47%.

The SPDR KRE ETF offers a more diversified approach, with 76 holdings and the top holding accounting for 1.9% of the overall portfolio. In comparison, the iShares IAT fund has 62 holdings and allocates 21.5% to USB.
