Evidence of the Nonstationarity of the Variance Rate of Return of New York Stock Exchange Listed Common Stock

The Financial Review, 1989, vol. 24, issue 2, 199-214

Abstract: The variance rate of return is shown to be nonstationary for the majority of stocks studied, with a median change of 100 percent over a period of one and one-half years. The degree of change declines as the interval between estimates is shortened as does the extent to which the variance rates of different stocks change in the same direction. The size and direction of the change do not appear to be strongly related to the trading frequency of the stock. Copyright 1989 by MIT Press.
