摘要：This paper conducts an empirical study on trade packages of 23 stocks of the Chinese stock market, each composed of a sequence of consecutive purchases or sales of a stock. We investigate the probability distributions of the execution time, the number of trades, and the total trading volume of trade packages, and analyse the possible scaling relations between them. Quantitative differences are observed between institutional and individual investors. The trading profile of trade packages is investigated to reveal the preference for large trades with respect to trading volume and transaction time of the day, and the different profiles of the two types of investors imply that institutions may be more informed than individuals. We further analyse the price impact of both the entire trade packages and the individual transactions within trade packages. We find that the price impact of trade packages is non-negligible over the period of the execution time and it may have a power-law relation with the total trading volume. The price impact of the transactions within trade packages displays a U-shaped profile with respect to the time of the day, and also shows a power-law dependence on the trading volume. The trading volumes of the transactions within trade packages made by institutions have a stronger impact on current returns, but the following price reversals persist over a relatively shorter horizon in comparison with those of individuals.
