The study looked at how prices of stock index futures are determined throughout the day on two different exchanges. They used data from May to November 2011 and found that China's CSI 300 index futures had a bigger role in setting prices compared to Singapore's A50 index futures. However, A50 futures also played a significant part in determining prices. When they looked at different time periods within the study, they saw that A50 futures were more influential in the first few months, while CSI 300 futures took over later on. These findings are important for traders and policymakers to understand how these markets interact.
