Hot markets, which refer to instances when stocks increase their offering prices to a level greater than average market premiums, have been overlooked in recent academic literature. Thus, this research examines factors which may aid in the prediction of hot issue markets. A sample of unseasoned stock issues offered between January 1, 1960 and October 31, 1970 is compiled, noting the stock's original offering price and their first two months' ending bids. In order to understand overall market performance during this time, data was also collected from the daily Standard & Poor 500 (SP the correlation between new issue premiums and aftermarket performance; the association between the number of monthly new offerings and simultaneous new issue premiums; and finally the correlation between new issue premiums and past market performance. Several implications for investors, issuers, and researchers are presented, as are directions for future research. The findings indicate that a level of predictability exists within the first month's residuals, which has implications for the timing of offerings and new issue purchases. A higher offering price, when compared to a cold issue market's efficient prices, may be obtained by issuers during that first month's issuance. (AKP)
