The New York Stock Exchange announced on December 20 that it levied $1.5 million in fines against a New York firm and its president for violations involving day trading and other activities.

During a five year period, Schonfeld Securities LLC, a Jericho, N.Y. firm, Steven Bart Schonfeld, president of the firm, and two other company officials violated exchange rules and regulations, according to a NYSE press release. They also ran afoul of Securities and Exchange Commission dictates.
