비용 산정 방식

왕복 매매 비용은 입력한 수량을 매수한 뒤 곧바로 되팔 때 드는 평균 비용을 달러로 나타낸 것입니다. 호가창에서 치르는 스프레드, 증권사가 직접 받는 수수료, 그리고 증권사 요금표에 명시된 경우 세금을 더합니다. 수수료 열은 스프레드를 뺀 이 비용입니다.

계산식

미국 상장 종목의 스프레드는 Rule 605에서 출발합니다. 100~499주 규모의 개인 투자자 주문이 가격 개선을 포함해 실제로 지불한 주당 실효 스프레드(달러)입니다. 이 값은 Nasdaq, NYSE, NYSE Arca, NYSE American, Cboe BZX에 똑같이 적용됩니다. 이어서 Rule 606을 바탕으로, 해당 브로커-딜러가 재량권 없는(held) 시장가 주문과 즉시 체결 가능한 지정가 주문을 어디로 보내는지에 따라 이 값을 조정합니다. 즉 종목의 가격 개선 후 605 스프레드에 증권사별 계수를 곱하며, 이 계수는 증권사가 이용하는 마켓메이커(홀세일러)에 맞춰 605 값을 보정합니다. Q 계수는 605 스프레드와 606에 나오는 각 마켓메이커의 스프레드 사이의 평균 비율입니다.

Q = Σt wt × 평균n St,nSn
스프레드 비용 = S × Q
Sn
종목 n의 전체 체결 장소를 합산한 Rule 605 실효 스프레드.
St,n
체결 장소 t에 해당하는 회사가 보고한 같은 종목의 스프레드.
wt
이 증권사의 재량권 없는(held) 시장가·즉시 체결 가능 지정가 주문 중 t로 보낸 비중(해당 증권사의 Rule 606 보고서 기준).

거래소, ATS, 이름이 공개되지 않은 체결 장소에는 비율 1을 적용하지 않습니다. 이들의 비율은 재구성한 호가 스프레드를 전체 실효 스프레드로 나눈 값입니다. 최우선 호가의 폭은 개인 투자자 주문이 실제로 지불한 수준보다 넓기 때문에, 주문 대부분을 그곳으로 보내는 증권사는 Q가 1보다 큽니다.

미국 외 시장의 스프레드는 매수호가와 매도호가의 차이를 베이시스포인트(bp)로 나타낸 것입니다. 각 측정값은 거래 시간 중 평균적인 시간대를 기준으로 보정하며, 공개하는 값은 이 측정값들의 중앙값입니다. Q 계수는 적용하지 않습니다.

스프레드(bp) = 매도호가 − 매수호가중간가 × 10,000
스프레드 비용 = 거래 금액 × 스프레드(bp) / 10,000

화면에 표시되는 왕복 매매 비용은 이 스프레드 비용에 증권사 수수료와 명시된 세금을 더한 금액입니다.
