SEC Chairwoman Mary Schapiro called the August 1 events at Knight Capital “unacceptable,” adding that:. . . existing rules make it clear that when broker-dealers with access to our markets use computers to trade, trade fast, or trade frequently, they must check those systems to ensure they are operating properly. And, naturally, we will consider whether such compliance measures were followed in this case.

Your share in any recovery will not be enhanced or diminished by the decision whether or not to serve as a lead plaintiff. Any member of the proposed class may retain Cohen Milstein Sellers & Toll PLLC or other attorneys to serve as your counsel in this action, or you may do nothing and remain an absent class member.
