摘要: The relationship between a market index and its constituent stocks is complicated. While an weighted average of stocks, when the investigated time scale one day or longer has been found to have stronger effect on than vice versa. We explore how this interaction changes in short scales using high frequency data. Using correlation-based analysis approach, we find that influence index. These findings implications for trading suggest price should be published shorter scales, as close possible those actual transaction scale.
