Motley Fool Stock Advisor pick optionsXpress (NASDAQ:OXPS) recently announced its monthly numbers for August. Although the company posted solid year-over-year growth, it wasn't immune to the jump in volatility and fearfulness that plagued the market in the past month.

optionsXpress, an online broker that competes with the likes of E*Trade (NASDAQ:ETFC), TD AMERITRADE (NASDAQ:AMTD), Schwab (NYSE:SCH), and Investools (NASDAQ:SWIM), posted decent numbers compared to last year. Daily average revenue trades, net new customer accounts, and ending client assets grew a respective 58%, 27%, and 25% compared to last year. However, on a sequential basis, those same metrics showed respective -10%, 2%, and -1% changes from the previous month.

All in all, I wouldn't read too much into the results. The markets are extremely jittery, which resulted in a loss of confidence and accounted for optionsXpress's lackluster sequential growth. One month is probably far too short a time period to judge optionsXpress' long-term prospects.
