As the straggler in the discount brokerage space, E*Trade (NYSE:ETFC) typically finds itself posting quarterly reports days after rivals TD AMERITRADE (NASDAQ:AMTD) and Charles Schwab (NASDAQ:SCHW) step up to the conference-call podium.

This time, at least, it was worth the wait. Revenue inched 9% higher to $664 million. Earnings before a one-time hit in its institutional equity business rose to $0.42 a share. The bottom-line showing is well ahead of the $0.36 per share it earned a year earlier, and the $0.40 per share that Wall Street was expecting.

Despite its financial bent, E*Trade wasn't stung by subprime woes in its lending business. It actually improved its credit quality during the period, with a reduction in bad loans. And with 45% in operating margins and watching over $213 billion in retail client assets, E*Trade is well-positioned, with or without any further industry consolidation.

OK, so maybe investors aren't convinced that E*Trade will escape free of scrapes from the subprime meltdown. Of the three discount brokers, E*Trade's stock is the only one trading lower than it did when the three companies posted their first-quarter results three months ago.

The end result is that E*Trade is starting to look like a relative bargain in this growing sector. Let's stack them up, shall we?

*Schwab did not provide guidance. The $0.93 is an analyst consensus estimate.

TD AMERITRADE has been on a roll, fueled by recent buyout speculation. Schwab, as the market leader, always seems to trade at a premium multiple. Still, E*Trade stands out as a cheapie. It continues to grow, now trading at just 10 times Wall Street's estimate of $1.91 per share come 2008.

The markdown doesn't seem fair. Even during yesterday's call, E*Trade emphasized the high FICO scores of its loans. The company believes that its high-quality borrowers would be more likely to refinance than to default on their loans. Besides, at the end of the day, this is still a discount broker, and the company is faring well in terms of subscriber growth as it opens new regional branches.

In concert, the three discount-broker bellwethers are looking pretty healthy. A few quarters ago, investors may have been concerned with unlikely providers offering commission-free trading like Bank of America (NYSE:BAC), Wells Fargo (NYSE:WFC), and Zecco.com. They don't seem to be much of a problem at the moment.

Investors know that quality companies are worth buying at low prices. When the stock happens to belong to a discount broker itself -- perhaps even your broker -- it seems to be a win-win situation.
