TD Ameritrade Holding Corporation (NASDAQ: AMTD) reported earnings for its second fiscal quarter yesterday, and they were pretty decent for the most part -- some might have thought that investors were completely shunning the market because of all the volatility going on, but TD Ameritrade's results show that a broker can still make money in such a challenging climate.

Even so, overall revenues declined 3% to $623 million. While transaction-based revenues also declined, it should be noted that average client trades per day did increase 23% to 312,000. That's an important measure when talking about brokers such as TD Ameritrade, or competitors such as E TRADE Financial Corporation (NASDAQ: ETFC) and The Charles Schwab Corporation (NASDAQ: SCHW). Earnings per share really shined, rising 35% to $0.31 per diluted share.

TD Ameritrade is sticking to its earnings guidance of a "midpoint forecast of $1.32." Of course, I'd like to see raised guidance, but a reaffirmation is certainly better than a reduction in guidance. Besides, I have to go back to the challenging climate concern -- if TD is happy to keep the forecast right now, then this is definitely positive. Investors would probably do well to at least investigate the brokers. When the economy snaps back, they should rally higher from these levels. TD Ameritrade, while not right up against a 52-week high, actually isn't that far from it, interestingly enough.
