Leading economic indicators, such as those that comprise the Composite Leading Indicator index, tend to presage changes in the economy, whereas the gross domestic product (GDP) is a coincident indicator that moves roughly in line with the economic cycle.

An economic indicator is a statistic that analysts use, along with other indicators, in an attempt to determine the general state of current economic activity and expectations of future activity.

Economic indicators: Three basic types

Indicators can be grouped into three general categories, depending when each may change relative to shifts in the economic cycle:

Leading indicators typically turn up or down before the general economy does. Common leading indicators include housing starts and building permits (suggesting the future volume of new construction), common stock prices, business inventories, credit card balances and other consumer debt trends, and corporate earnings.
Coincident indicators normally move in line with the overall economy and can be used to confirm (or possibly disprove) changes in the economy previously anticipated by leading indicators. Examples of coincident indicators include industrial production, business and consumer sales, gross domestic product (GDP), and similar data points that peak or bottom out as the economy does.
Lagging indicators are those that typically change direction after the economy does. Lagging indicators are useless for prediction, because they measure economic effects that have already occurred, but they can be useful for confirmation. Changes in the unemployment rate and other jobs data, for example, tend to come after the cycle has already shifted. Interest rates are another example of a lagging indicator, as central banks such as the Federal Reserve make monetary policy adjustments based on changes in the economic environment.

Investing through economic cycles

The economic cycle (also called the “business cycle”) generally comprises four phases: expansion, peak, contraction, and recovery. The duration of an economic cycle—and each phase within it—can vary greatly from cycle to cycle. For example, from 1857 to 2020, the U.S. economy has seen a peak-to-trough cycle as short as two months and as long as 65 months, according to the National Bureau of Economic Research (NBER).

Certain phases of the cycle tend to favor specific sectors of the market. For example, technology and consumer discretionary stocks tend to perform well during an expansion; “defensive” stocks such as consumer staples and utilities tend to outperform during a contraction. Although timing the market can be difficult even for market pros, it helps to understand which economic indicators tend to lead the market and which ones may be coincident or lagging.
