The Impact

In April 2017, China Financial Futures Exchange adjusted the maximum order volume of single trading in stock index futures, and this paper conducts research on this event. Firstly, it analyzes the influence of the adjustment of maximum order volume on the characteristics of the limit order book with high-frequency data and the impact of ordering situation on the trading depth and volatility of each contract with panel data. Secondly, it takes high-frequency tick-by-tick data to explore the causal relationship between the ordering situation and the probability of informed trading and analyzes the impact of the event on the probability of informed trading. Finally, the dynamic factor analysis method is used to quantify the pricing efficiency based on the probability of informed trading and the characteristics of limit order book, and the influence of the event on the pricing efficiency of stock index futures market is discussed. The results show that the reduction of maximum order volume has different effects on dominant contracts and nondominant contracts of stock index futures. After the event, the overall trading volume of the market increased, where the trading volume of dominant contracts decreased and that of nondominant contracts increased. For dominant contracts, the depth, slope, and liquidity decrease, the spread increases, and the probability of informed trading decreases so that the pricing efficiency becomes worse, while the results of nondominant contracts are the opposite. For Chinese stock index futures market, the pricing efficiency is greatly reduced and the resource allocation capacity is weakened under the influence of the event. Therefore, the adjustment of maximum order volume is not conducive to the healthy development of the stock index futures market. It is suggested that the reduction of the maximum order volume is only implemented for nondominant contracts.

Probability Of Informed Trading

Information is one of the important factors that influence the behavior of investors and then have an effect on the price of the risky assets in the market. Firstly, the new procedure developed by Easley et al. (2011) is used to estimate the Volume-Synchronized Probability of Informed Trading (VPIN) of the Chinese stock index futures market. Then VPIN for special scenarios is depicted. As a result, we find that the future contracts generally have a larger number of information transactions. We also find that, for particular scenarios, the probability of informed trading in the market has obvious exceptions. The larger proportion of informed trader is, the higher the volatility of the price is.

Probability Of Informed Trading

The market microstructure theory and high-frequency trading analyze as quantitative investment’s frontier and hot issue is popular in China in recent years, but China’s stock index futures introduced later, so there are not much academic attention. This paper measures the probability of informed trading in China’s stock index futures market by VPIN method. The empirical results show that the VPIN can not only monitor the probability of the informed trading market of IF 300, IH 50 and IC 500, but also play an early warning role before the “circuit-breaker”. Tracking VPIN values allows the liquidity providers to control their position risk, and regulators can monitor the liquidity quality of the market, limit transactions in advance or tighten market controls.

The Impact

We have examined the order book characteristics and market impact on the Korean stock index futures market (KOSPI 200 index futures). The distribution of order volumes generally follows power-law distribution. The estimated exponents are 1.9 for market order, 2.5 for limit order, and 2.1 for cancel order. This result is different from the case of stocks where the exponent of market order is larger than that of limit order. The order likelihood is distinctively high in every 50's of order volume, which implies the behavioral characteristics of human preference on round-up numbers. The distributions of bid–ask spread and the best quotes volume provide the evidence of the liquidity of KOSPI 200 index futures market. We have obtained the concave relationship between market impact and transaction volume as well. Finally, the market response behavior is observed regarding various transaction sizes. The size of market response is estimated to be proportional to the size of transaction. Also, the larger the transaction size is, the longer it takes to recover the stability from the impact triggered by transaction.

This study investigates the trading activity of Chinese stock index futures, recently introduced at the open and close of the underlying trading. We document the impact of the underlying spot on the futures market liquidity as well as volatility as discussed in earlier works on market closure theory. Our empirical results support previous literature on the impact of the underlying, particularly during the open session, as a contagion effect, which is clearly at play. We find significant U-shaped patterns in liquidity factors and intraday volatility during open and close trades in the morning.

The Impact

In this study we examine the relationships between trader-type-specific trading volumes and the price volatility of the KOSPI200 stock index futures over the period of July 1997 through December 2001. The principal findings of this study are that the changes in trading volumes by foreign investors are positively associated with the return and the volatility of the index futures market. When trading volumes are decomposed into expected and unexpected components, unexpected shocks have more persistent effect on the volatility of the market than expected component. Meanwhile, individuals and domestic commercial investor seem to follow the lead made by foreign investors.

The Impact

Since China’s first stock index futures, China Securities Index 300 (CSI300) stock index futures were published in 2010, and China’s stock index futures market is now in a period of rapid development and play a key role in price discovery. During 2014 to 2015, China’s stock index futures market fluctuated abnormally, and the overuse of high-frequency trading (HFT) strategies in the stock index futures market was blamed as the main reason of the abnormal volatility. To lower down market fluctuation, the regulatory institute then announced a series of trade restriction policy to prevent the overuse of HFT behaviour. However, until now, the impact of such trade restriction policy for HFT remains uncertain. To tackle this issue, based on minute-level HFT data from the CSI 300 index futures market, this paper aims to investigate the relationship between HFT and the exogenous liquidity risk and how HFT affects China’s stock index futures market on its liquidity using the liquidity-adjusted value at risk (LVaR) model. The findings indicate that HFT improves the return of the liquidity provider and reduces the exogenous liquidity risk significantly.

New Evidence

We investigate the impact of stock index futures on the information environment of listed firms through the launch of Shanghai-Shenzhen 300 stock index futures (CSI 300 index) as natural experiment on April 16, 2010. We employ difference in difference analysis and apply the PIN indicator (the probability of informed trading) to measure information asymmetry. We found that the CSI 300 index significantly reduce the information asymmetry of CSI 300 companies. For the companies with higher market capitalization, higher turnover rate and higher institutional investor’s rate, the impact of stock index future on the corporate information environment is more significant. The results of this paper provide new evidence for evaluating the impacts of Chinese stock index futures.
