2 5 AR(3) What Will Happen When Stock Price Close to the Limit? ---Evidence From the Shanghai Stock Exchange Guotai Jun'an Securities Research Institute (No.2008, Chunfeng Road, Shenzhen , China) ABSTRACT: This paper investigates the influence of the price limit to the return of stock price by using 5 minutes data in the Shanghai Stock Exchange. To see what will happen when stock price is close to the limit, we use two methods in our empirical research: a regression analysis of AR(3) model and a transfer probability analysis. The results of the two methods are same that there is a cooling off effect in Shanghai Stock Market due to the price limit. The stock price of next 5 minute is more possible downward when the current price is close to the upside limit and is more possible upward when the current price is close to the downside limit. The cooling off effect is asymmetrical with a stronger rebound near the downside limit and can not be treated as a result of the reversal effect existed in the intra-day return of stock price. KEYWORDS: price limit cooling off effect reversal effect regression analysis transfer probability analysis - 2 -
