E.T.F. Trades Without Fees.

You can add Vanguard to the list of brokerage companies that have lowered their trading commissions and waived trading fees on exchange-traded funds, a move that will apply to all 46 of its funds. Exchange-traded funds are basically mutual funds that trade like stocks. They are pegged to indexes that track different parts of the market. E.T.F.'s also tend to be less expensive and more tax-efficient than their mutual fund counterparts. [ABSTRACT FROM PUBLISHER]
