앞 글에서 정산가를 언급하고 잠시 구글검색을 해보니 다음과 같은 문서가 있네요. 이전에 증권사나 선물사에 전화를 해도 참 난해하게 설명을 해서 이해가 안되었는데 간단한 산출예시를 보니 단번에 이해가 갑니다.
What is a Settlement Price?
Settlement price refers to the market price of a derivatives contract at the close of a trading day.
How Does a Settlement Price Work?
Also called the closing price, the settlement price is the price at which a derivatives contract settles once a given trading day has ended. It is also the market price at which a given contract begins trading at the opening of the next business day. It is commonly determined by the price of the final trade prior to the closing bell or by averaging the spot price in the final minutes of a trading session.
To illustrate, suppose derivatives contract XYZ's last trade before the close of a day's trading is $100. The settlement price for XYZ will, consequently, be listed as $100.
To illustrate the latter case, suppose the derivatives market trading session ends at 4:00 P.M. At 3:58, XYZ's market price is $98, at 3:59, $97; and then at the closing bell of 4:00, $98. Taking the average of these market prices in the last three minutes of trading gives us a settlement price of $97.66.
후자의 경우를 설명하기 위해, 파생시장 세션이 오후 4시에 끝난다고 가정하자. 3시58분에 XYZ의 시장가격은 98달러, 3시59분에 XYZ의 시장가격은 97달러, 4시 마감시점에 98달러. 마지막 3분의 시장 가격의 평균으로 97.66달러의 정산가격을 얻을 수 있다.
Why Does a Settlement Price Matter?
The settlement price of a derivatives contract is crucial for investors because it indicates whether they lost or made money on a given trading day. In the event that losses were incurred, the settlement price signals whether or not investors need to infuse funds into their margin accounts to compensate.
