It's always smart to do some investigating when founders and CEOs decide to leave their companies. So get out your magnifying glasses, Fools: CEO David Kalt announced plans to depart Stock Advisor selection optionsXpress (NASDAQ:OXPS) at the end of next month.

In this case, I found no major red flags. There seems to be a reasonable succession plan in place, with current president and former CFO David Fisher ready to step up to the plate. In addition, Ned Bennett and James Gray, who co-founded the company with Kalt, will continue as chairman and executive vice-chairman of the company, respectively.

Kalt said he's leaving to pursue other earlier-stage entrepreneurial opportunities. Although CEO departures are almost always explained with legal boilerplate, I think it's reasonable for a company's founder to get the itch to return to his entrepreneurial roots. The company did mention that Kalt will remain one of optionsXpress' largest shareholders.

It's a consolidation-happy industry, with E*Trade (NASDAQ:ETFC) and TD AMERITRADE (NASDAQ:AMTD) currently in merger talks. I won't speculate on the implications of Kalt's departure on his company's merger prospects. I'll simply note that I wouldn't be surprised if brokers like Schwab (NASDAQ:SCHW) and Interactive Brokers (NASDAQ:IBKR) wanted to get their hands on optionsXpress and its desirable customer base.
