Talk about your executions! No sooner had E*Trade (NYSE:ET) offered guaranteed two-second stock trade executions on small orders yesterday than Standard & Poor's disclosed that the discount broker will replace FleetBoston Financial (NYSE:FBF) in its benchmark S&P 500 index.

FleetBoston had to go. Bank of America (NYSE:BAC) is now just days from closing its acquisition. It was logical for Standard & Poor's to seek out a worthy financial services company to take its place. But an online discount broker?

We've come a long way, Fool!

It was tricky for a while there, but a steady flight back into stocks coupled with a growing online populace have discount brokers back in vogue. This is reflected clearly in the stock performance of dot-com specialists like Ameritrade (NASDAQ:AMTD) and E*Trade, with both having more than doubled over the past year.

Our Broker Center has been a key part of our site through it all. We view empowering the individual investor as a worthy cause, and discount brokers play a role. That it's E*Trade going into the index is especially cool. Leading discount broker Charles Schwab (NYSE:SCH) and Toronto Dominion's (NYSE:TD) TD Waterhouse have been around for decades, but E*Trade is as close as you get to a poster child for the Web-fueled future.

E*Trade promotion to the big index is an endorsement for online brokers everywhere. The thrifty and self-sufficient have been heard.
