Abstract

After the adoption of zero-commissions by major brokers, they increasingly route orders to wholesale market makers to possibly earn payment for order flow given the loss of commissions. Retail investors assets held by zero-commission and commission-charging brokers increase 7 % and decrease 9 %, respectively. Retail investors earn less price improvement per share and submit more orders and smaller orders. Effective spreads decline because retail limit prices are increasingly posted within the bid-ask spread. Intraday volatility increases and price impact falls, as orders become more uninformed, while realized spreads remain unchanged.
