To identify the appropriate market performance measures and prediction models for the emerging markets, this study first reviews the past literature on IPO market performance.

The market performance has been analysed in two aspects; the initial or short-term market performance and the long-run market performance.

The initial market performance is a universal phenomenon and it is measured by raw returns and excess returns. The longrun IPO performance was mainly analysed under the two approaches; event-time approach and calendar-time approach.

In the event-time approach, the cumulative abnormal return, average raw return, buy-and-hold return, and wealth relatives are used to measure the long-run performance. The Capital Assets Pricing Model, Fama-French model and indices are the main measures that were employed under the calendar-time approach.
