There is a remarkable body of empirical facts which indicates that successive cost changes in person common stocks are very almost independent. Recent papers simply by Mandelbrot and Samuelson show rigorously that independence of successive value changes is consistent with an " efficientвЂќ market, i actually. e., a market that sets rapidly to new information. It is important to note, however , that in the scientific work thus far the usual method has been to infer industry efficiency from the observed independence of effective price alterations. There has been little or no actual tests of the speed of modification of prices to specific types of new details. The prime concern of this daily news is to examine the process by which common stock prices adapt to the information (if any) that may be implicit within a stock divide. In doing thus we suggest a new " event studyвЂќ methodology pertaining to measuring the consequences of actions and events in security rates.

effective Price within individual prevalent stocks are very nearly 3rd party. 2 The latest papers by Mandelbrot (1966) and Samuelson (1965) display rigorously that independence of successive selling price changes is consistent with a great " efficientвЂќ market, i actually. e., an industry that adjusts rapidly to new data.
It is important to note, however , that in the scientific work as of yet the usual procedure has been to infer market efficiency from the observed independence of effective price improvements. There has been hardly any actual testing of the acceleration of realignment of prices to specific sorts of new information. The prime concern of this conventional paper is to examine the process in which common share prices conform to the information (if any) that is certainly implicit in a stock break up.
This kind of study method suggested to us simply by Professor James H. Lorie. We are pleased to Professors Lorie, Merton H. Burns, and Harry V. Roberts for many useful comments and criticisms. The study reported here was...
