Abstract
Uniquely addressing asynchronous informational update between index and futures, we find that reduction in data frequency depicts a dual effect of “noise reduction” and “speed reduction” on Hasbrouck’s (1995) information share (IS) and Gonzalo-Granger’s (1995) component share (CS) indicators. Furthermore, the “noise reduction” effect does not exist significantly on CS, thereby preventing Putniņš’s (2013) information leading share (ILS) indicator from eliminating noise under low-frequency data. Our novel leading time (LT) indicator suggests that the Shanghai-Shenzhen Stock Exchange 300 (CSI 300) and China Stock Exchange 500 (CSI 500) futures dominate price discovery. An asynchronous informational update overestimates the price discovery ability of futures.
