S&P Global Composite PMI
The S&P Global Composite Purchasing Managers Index (PMI), released on a monthly basis, is a leading indicator gauging US private-business activity in the manufacturing and services sector. 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 private economy is generally expanding, a bullish sign for the US Dollar (USD). Meanwhile, a reading below 50 signals that activity is generally declining, which is seen as bearish for USD.
