    The degree of predictability of UK share returns is examined using variance ratio and rescaled range tests. The tests are constructed using a dissagregate weekly data base spanning the period January 1982 to June 1990. The main conclusion is that the vast majority of share prices are characterized by a simple random walk process. This finding contrasts with the recent US literature, but supports the ‘traditional’ view of the behaviour of stock prices.
