Investors are always looking for good opportunities to obtain short- term returns, which is why the early days of the issuance of stocks can be a good opportunity for investors in all capital markets all over the world. Every year, many companies by offering their shares to the public through the capital market, provide their financial needs. But these companies think less and make less decision about their low priced stocks or availability of unusual short-term returns which is the income of their investors. According to this fact, earning abnormal positive returns is the interest of buyers and the disadvantage of the previous owners who attempted initial public offering (Yaghoobnezhad and Tajik Nia, 2010).

Conservatism is a factor that can influence both the relevance and reliability of the information, and if these two properties change, the power to decide who rely on the financial information will be also changed.
