S&P Global Composite PMI

The Composite Purchasing Managers Index (PMI), released on a monthly basis by S&P Global, is a leading indicator gauging private-business activity in UK for both the manufacturing and services sectors. The data is derived from surveys to senior executives. Each response is weighted according to the size of the company and its contribution to total manufacturing or services output accounted for by the sub-sector to which that company belongs. Survey responses reflect the change, if any, in the current month compared to the previous month and can anticipate changing trends in official data series such as Gross Domestic Product (GDP), industrial production, employment and inflation.The index varies between 0 and 100, with levels of 50.0 signaling no change over the previous month. A reading above 50 indicates that the UK private economy is generally expanding, a bullish sign for the Pound Sterling (GBP). Meanwhile, a reading below 50 signals that activity is generally declining, which is seen as bearish for GBP.
