  15. We analyse the dispersion of stock returns and have the tests of serial correlation. the results show that the trading mechanism has a significant effect on a number of characteristics of stock returns. first, the distribution of open - to - open returns has greater variance than that of close - to - close returns. second. the serial correlation pattern is quite different in the two return series. the open - to - open returns have negative autocorrelation coefficient, but the close - to - close returns is positive. further, employing an arma ( 1, 1 ) model we find that in the opening. returns exhibit higher residual noise and stronger dependence on past returns, reflecting stronger deviations from the random - walk form of the market efficiency hypothesis
