What is the SPX price?
The SPX quote you see is the weighted average of all the last prices of the 500 component stocks. If a stock changes price, the SPX price changes a little, too. While most of the 500 stocks are trading pretty actively in the middle of the trading day, that's not necessarily the case at 8:30 a.m. CT in the morning. Just before the open, the price of the SPX is being calculated off the last prices of the 500 component stocks from the night before. At 8:30, some, but not all, the stocks start trading, and the SPX starts to change. The open price you see for the SPX is based on some current and some old data. The current data is for the stocks that are trading at 8:30. The old data is for the stocks that haven't traded yet, and is from yesterday's close. That's crucial because the settlement price of the SPX can be determined only when all 500 stocks have traded with an opening price. As I said, some have their opening price at 8:30, but others might not open until 8:45. If the overall market moves in those 15 minutes, the SPX settlement price has some of its data from before the move and some from after the move.
