SEC Rule 606 Reporting

SEC Rule 606 requires broker-dealers that route customer orders in equities and option securities to publish quarterly reports that provide an overview of their routing practices. MSEC, LLC introduces transactions on a fully disclosed basis to our clearing firm, National Financial Services, LLC (“NFS”). NFS has prepared reports pursuant to SEC Rule 606. The report provides information on the routing of “non-direct orders,” which are orders that the customer has not specifically instructed MSEC to be routed to a particular venue for execution. For non-direct orders, NFS has selected the execution venue on behalf of its customers.

The report is divided by month and each month includes orders separated by securities that are included in the S&P 500 and other non-S&P 500 stocks, and a separate section for listed options. The report will also identify the venue to which NFS routed the orders and, for each venue, the statistical information broken down by order type. For example, whether the order type was a market order, marketable limit order, non-marketable limit order and other orders.
