考虑交叉影响成本的股票对交易策略

Trading strategies for stock pairs regarding to the cross-impact cost

Shanshan Wang

摘要:

我们将Gatheral [2010]的交易策略框架从单一股票扩展到一对股票。我们的交易策略执行了两个来回的交易,可以描述成对股票的交易率和交易周期的比例。通过尽量减少交叉影响所产生的潜在成本,一只股票的价格变化,由于另一只股票的交易,我们可以找到一个最佳的策略,执行一系列的交易,从不同的股票。我们进一步应用模型的战略,以一个特定的情况下,我们量化的交叉影响的交易量和时间滞后的经验数据计算成本。因此,我们描绘了交叉影响对交易策略的影响。

英文摘要:

We extend the framework of trading strategies of Gatheral [2010] from single stocks to a pair of stocks. Our trading strategy with the executions of two round-trip trades can be described by the trading rates of the paired stocks and the ratio of their trading periods. By minimizing the potential cost arising from cross-impacts, i.e., the price change of one stock due to the trades of another stock, we can find out an optimal strategy for executing a sequence of trades from different stocks. We further apply the model of the strategy to a specific case, where we quantify the cross-impacts of traded volumes and of time lag with empirical data for the computation of costs. We thus picture the influence of cross-impacts on the trading strategy.
