E-Trade Financial Corporation /zigman2/quotes/205731930/composite ETFC +4.68% on Wednesday said it would eliminate retail commissions for online trades of U.S.-listed stocks, options and exchange-traded funds. The move comes after online brokerage rival Charles Schwab Corp. /zigman2/quotes/201281754/composite SCHW +2.72% on Tuesday dropped commissions on U.S. stocks, ETFs and options, a move that was followed by TD Ameritrade /zigman2/quotes/207561492/composite AMTD +2.81% . E-Trade said it would also reduce its options contract charge to 65 cents per contract for all traders, while maintaining its active trader pricing at 50 cents per contract. The changes will take effect Oct. 7. The company said it estimated the impact of the commission changes on second-quarter operating results would have been around $75 million. Shares of online brokers have sold off sharply since the Schwab move.
