Is There an Accruals or a Cash Flow Anomaly in UK Stock Returns?

Abstract

In this paper, we apply a modified one-stage version of the Mishkin (1983) test to companies in the UK stock market in order to investigate the presence or otherwise of the accruals anomaly in UK firms’ annual returns. For the period of 1990-2007, we report that there is little evidence of a general accruals anomaly in the UK, in which accruals have a negative relationship with future returns, once risk and other potential forecasting variables have been accounted for. We also provide evidence that, after winsorising extreme observations, there is a cash flow anomaly in the UK stock market. We also find evidence in favour of an anomaly with respect to capital expenditure growth. Another interpretation is that the accruals anomaly is not distinct from other anomalies in the UK market, whereas the cash flow (and the capital expenditure growth) anomaly is.
