It's because he has to.

Griffin, CEO of Citadel, defended the industry as one that has helped market participants and lowered costs, but is also populated by firms that have to jealously guard their strategies and keys to success. "What's shocking to those of us in the community is how many important ideas can be expressed in two sentences," Griffin said Wednesday at the Delivering Alpha conference presented by CNBC and Institutional Investor. "Because they are often very simple to record, you have to be careful how you express those ideas."

In Michael Lewis' controversial and much-discussed book "Flash Boys" released earlier this year, Citadel was cited in an anecdote for its secrecy. One passage noted that it took an employee five ID card swipes simply to start her day. Griffin said that's probably about right, but he refused to apologize for the steps his firm takes to guard its intellectual property.
