Long-Term Stock Price Reversals in the UK: Evidence from Regression Tests

Abstract

This paper seeks to advance our knowledge about the UK evidence on long-term stock price reversals. Many of the major studies of long-term reversals have been done using US data, prompting fears about data snooping biases. There have been comparatively few UK studies and they have all employed contrarian portfolio techniques to identify evidence of reversals. None of these UK studies has used cross-section regression tests, which have been employed in some of the US investigations, and this paper aims to fill this gap. We find evidence of stock price reversals, even after controlling for time-varying risk and restricting the study to larger, UK-listed companies-that is, companies that are frequently traded, more heavily regulated and extensively analysed by market commentators, analysts and institutional investors.
