The iShares Dow Jones U.S. Broker-Dealers Index Fund (NYSEArca: IAI) offers investors a unique way to tap into the strengthening financial sector without betting on any specific company stock, according to a new article from MarketWatch's John Spence.

Though the fund—which invests in companies like Charles Schwab and Goldman Sachs—lost significant ground recently following the slump in the stock market, it is still up more than 90 percent from its March lows.

With an expense ratio of 0.48 percent, IAI has about $190 million in assets, and it competes against the SPDR KBW Capital Markets ETF (NYSEArca: KCE), which is the only other ETF available to provide exposure to the broker-dealer sphere. KCE has an expense ratio of 0.35 percent and just over $100 million in assets.
