With a healthy stock market and stronger economic conditions, it's neither secret nor surprise that investors have returned to the markets. That said, few businesses reflect these trends better than that of Motley Fool Stock Advisor pick Charles Schwab (NYSE:SCH).

Trading volumes reached record levels in January, benefiting Schwab, as well as rivals Ameritrade (NASDAQ:AMTD), E*Trade (NYSE:ET), and Toronto-Dominion's (NYSE:TD) TD Waterhouse. While that trading has slackened a bit since, it is still going strong.

This morning, Schwab reported that daily average revenue trades in February clocked in at 166,900. Though that figure is down 22% from January, that still represents a whopping 53% improvement from Feb. 2003. Late last week, Ameritrade reported a similar trend with like strong results, prompting the company to raise the low end of its quarterly EPS projection.

But in another strong reflection of the market's performance, Schwab also noted that its total client assets had climbed a healthy 33% over the past year. That gain, along with $3.3 billion in net new assets, put Schwab's client assets over the $1 trillion mark for the first time since Aug. 2000.

So things have been pretty good of late, no doubt. But will the good times continue? Given the market's recent action, that's a good question with no easy answer.
