Order-based manipulation: evidence from Hong Kong stock market

Abstract

Purpose

The paper aims to investigate order-based manipulation that consists of order-placing strategies.

Design/methodology/approach

Using the bid and ask record provided by Hong Kong Exchanges and Clearing Limited, a Level II dataset, the paper develops a methodology to obtain cancelled orders during regular trading hours. The paper examines the cancelled orders and potential order-based manipulation activities, as well as the corresponding behavior of different groups of stocks.

Findings

Empirical results show that the relationship between order cancellation and order-based manipulation is strong and deserves more attention.

Originality/value

The methodology can also be used by regulators and authorities to monitor suspicious activities in the market. This paper also suggests that analysis on high-frequency data does improve the understanding of trading activities in the stock market.
