Stock Market Prices Do Not Follow Random Walks long holding-period returns are significantly negatively serially correlated, implying that 25 to 40 percent of the variation of longer-horizon returns is predictable from past returns. In this chapter we provide further evidence that stock prices do not follow random walks by using a simple specification test based on variance estimators. Our empirical results indicate that the random walk model is generally not consistent with the stochastic behavior of weekly returns, especially for the smaller capitalization stocks.

The advantages of the concept of relative efficiency, as opposed to the all-or-nothing notion of absolute efficiency, are easy to spot by way of an analogy. Physical systems are often given an efficiency rating based on the relative proportion of energy or fuel converted to useful work. , heat, light, noise, etc. Few engineers would ever consider performing a statistical test to determine whether or not a given engine is perfectly efficient-such an engine exists only in the idealized frictionless world of the imagination.

Motivated partly by an insight of Merton's (1980), that variances can be estimated more accurately than means when data is sampled at finer intervals, we proposed a test of the random walk based on a comparison of variances at different sampling intervals. And 14 Part I by casting the comparison as a Hausman (1978) specification test, we were able to obtain an asymptotic sampling theory for the variance ratio statis tic almost immediately, which we later generalized and extended in many ways. These results and their empirical implementation are described in Chapter 2.
