The monthly volatility of IPO initial returns is substantial, fluctuates dramatically over time, and is considerably larger during quot;hotquot; IPO markets. Consistent with IPO theory, the volatility of initial returns is higher among firms whose value is more difficult to estimate, i.e., among...

This paper analyzes the relation between real stock returns and real activity from 1889-1988. It replicates Fama's (1990) results for the 1953-87 period using an additional 65 years of data. It also compares two measures of industrial production in the tests: (1) the series produced by Babson...

Monthly stock returns from Smith and Cole [1935], Macaulay [1938] and Cowles [1939] are compared and contrasted with the returns to the CRSP value and equal-weighted portfolios of New York Stock Exchange (NYSE) stocks. Daily stock returns from Dow Jones [1972] and Standard amp; Poor's [1986] are...

We use predictions of aggregate stock return variances from daily data to estimate time varying monthly variances for size-ranked portfolios. We propose and estimate a single factor model of heteroskedasticity for portfolio returns. This model implies time-varying betas. Implications of...

This paper compares several statistical models for monthly stock return volatility. The focus is on U.S. data from 1834-19:5 because the post-1926 data have been analyzed in more detail by others. Also, the Great Depression had levels of stock volatility that are inconsistent with stationary...

This paper analyzes the relation of stock volatility with real and nominal macroeconomic volatility, financial leverage, stock trading activity, default risk, and firm profitability using monthly data from 1857-1986. An important fact, previously noted by Officer [l973], is that stock return...
