Investors want to keep their finger

Investors want to keep their finger on the pulse of the economy because it usually dictates how various types of investments will perform. The stock market likes to see healthy economic growth because that translates to higher corporate profits. The bond market prefers more subdued growth that won't lead to inflationary pressures. By tracking economic data such as industrial production, investors will know what the economic backdrop is for these markets and their portfolios.

The index of industrial production shows how much factories, mines and utilities are producing. The manufacturing sector accounts for less than 20 percent of the economy, but most of its cyclical variation. Consequently, this report has a big influence on market behavior. In any given month, one can see whether capital goods or consumer goods are growing more rapidly. Are manufacturers still producing construction supplies and other materials? This detailed report shows which sectors of the economy are growing and which are not.

The capacity utilization rate provides an estimate of how much factory capacity is in use. If the utilization rate gets too high (above 85 percent), it can lead to inflationary bottlenecks in production. The Federal Reserve watches this report closely and sets interest rate policy on the basis of whether production constraints are threatening to cause inflationary pressures. As such, the bond market can be highly sensitive to changes in the capacity utilization rate. In this global environment, though, global capacity constraints may matter as much as domestic capacity constraints.
