Abstract

Using 123 prosecuted cases of closing price manipulation from the Hong Kong Stock Exchange, we present the first evidence of quote-based manipulation, whereby manipulators inflate closing prices solely using quotes. Quote-based manipulation increases closing prices, bid returns, and order frequencies immediately prior to market close. In contrast to previous studies, illiquid stocks are found to be most susceptible. The manipulation appears to deceive investors, with gradual price increases observed subsequent to the manipulation, allowing manipulators to earn profits. Potential manipulations continue to be observed, suggesting illiquid stocks would benefit from a non-continuous call auction mechanism, as used in many European markets.
