IPO Underpiricing, Konservatisme Akuntansi, dan Sentimen Investor
Abstract. The significant increase of stock price compared to its IPO price is difficult to explain. Companies which issue their stock are impossible to set underpriced IPO voluntarily, while investors who buy an overpriced stock are only they who are not rational or lack of information. Conservative financial statements and high accrual quality provide an opportunity for all investors to be able to estimate the fair price of IPO shares so that the disagreement among investors is not too wide and price fluctuations due to speculation are not too high in the secondary market. Using Indonesia Stock Exchanges, the results show that influence of accounting conservatism and accrual quality are stronger in the 30 holding period after the IPO because the uncertainty of financial statement information led to wider speculation opportunities in the long period. The rise in stock prices after IPO is also influenced by investor’s sentiment and market conditions Keywords: IPO, underpricing, accounting conservatism; accrual quality, investor sentiment
