Given the recent political landscape of the UK with the Labour Party forming a government for the first time since 1979, it is hardly surprising that the performance of the stock market under Tory and Labour governments is a topic of media and general interest. The primary purpose of this paper is to analyse the movement of the UK stock market over the post-war period against the background of different political parties being in power. The evidence presented concerning short-term share price movements indicates that the stock market responds both to the findings of opinion polls in the run up to elections and to elections themselves. Furthermore, the results from elections (inclusive of 'surprise' elections) indicate that there is a clear preference for a Tory government. In terms of share price movements across the period of a government's office, however, there is no statistically significant evidence (at commonly accepted confidence levels) to suggest that the stock market has performed better in either nominal or real terms under Tory government. In addition, via a simple comparison of share prices for the first and second halves of political terms of office, there is no evidence that either party is able to manipulate the economy and/or the market for election purposes. Given that longer-term share price movements do not support the short-term share price movements around elections, a number of key economic variables are examined. These indicate that Tory governments are not associated with superior performance in either real increases in GDP or company profits but that they have seen statistically significant lower levels of average inflation and higher average levels of real interest rates. As for share prices the paper considers whether the economic variables differ between the first and second halves of political terms of office; the results do not provide support for the management of economic variables for election purposes. Such a conclusion is supported by a more detailed analysis of GDP across political terms of office.
