Description:
Using detailed order handling data, we find that brokers who route more orders to affiliated Alternative Trading Systems (ATSs) are associated with lower execution quality (lower fill rates and higher implementation shortfall costs) for their customers. To separate clients' preference for ATSs from brokers' routing decisions, we confirm these results for orders where brokers have more order handling discretion, matched broker analysis that accounts for ATS usage, matched child orders that account for client intent, and based on an exogenous constraint on ATS venue choice. Our results suggest that more disclosure on order routing practices will improve execution quality
