Abstract: This paper analyzes intraday interdependence of returns and trades between Chinese equity and warrants markets based on a vector autoregression framework proposed by Chan et al. (2002). We find that both stock and warrant trades contain useful information for revealing quotes in the stock and warrants markets using 60- and 100-second data frequencies. However, when the data frequency is reduced from 100 seconds to 5 minutes, we find that stock volume has a negative impact on contemporaneous stock returns, which contradicts the informational effect of stock-trading activities.
