Leading vs Lagging Indicators

A leading indicator is an economic factor that tends to change before the economy starts to change and helps investors and market participants to predict changes in the economy, whereas a lagging indicator is a measurable economic factor based on the changes in the economy; this means that when there is a change in the economy, there will be a change in the lagging indicators. Traders use lagging indicators to arrive at transaction signals of a trend.

Leading vs lagging indicators in trading are economic factors that enable the measurement of current market conditions and forecast market trends. To arrive at a certain indicator, statistical computing needs to be performed. Indicators enhance economic forecasting for market makers, organizations, economists, and investors alike.

1. A lagging indicator is a measurable economic factor based on the changes in the economy. In contrast, a leading indicator is an economic factor that tends to change before the economy changes.
2. Leading indicators show the changes in the future due to movements in the segments of the economy; lagging indicators actualize the happenings of the economy using facts and figures.
3. Both are economic factors, leading indicators are used by economists, traders, or investors to predict an economic change, and lagging indicators prove the information regarding the change. 

Leading indicators have behavior to change before the economy changes. It might not be wrong to say that these indicators result in a change in the economy. These indicators change before the economy starts to make its move. Due to its preemptive nature, economists and traders rely on leading indicators to arrive at conclusions regarding forecasting significant shifts in the market.

Since these are just indicators, at times, they aren't accurate. But, when put together with other data from the market, these indicators can be a key factor in forecasting the economy. This is because leading indicators are aggregated data collated by qualified sources and focus on specific economic segments.

An example would be the Purchasing Managers Index (PMI) which economists and traders closely monitor to forecast the Gross Domestic Product (GDP).

Another example would be the number of jobless claims, which indicates a weak economy. A rise in jobless claims would eventually harm the economy and the market. Inversely, if jobless claims dip, it showcases that the companies are doing good, resulting in a stronger market.

Lagging indicators are economic factors that have behavior to change post changes in the economic scenario. Movements in lagging indicators become evident only after the economy has moved in a particular direction and started to follow a particular trend. A lagging indicator does not help predict changes in the economy; however, it helps determine the after-effects of the change in the economy's trend. Since these indicators are an outcome of a change in the economy, traders and economists can use lagging indicators to generate signals.

Quantitative investment strategies rule-based securities function based on the signals that are arrived at with the help of lagging indicators. The impact of an economic change and its trend is mimicked by the lagging indicator, which trails the price of the underlying asset.

An example would be the moving average of any security, which becomes traceable only after a change in the security price. As a result, the moving average has a flaw since there is a high possibility that the significant move may have occurred at a time not included in the calculation. This would result in entering the trade later, which may not be profitable.

Let's see the top differences between leading vs lagging indicators.

Any indicator can lead to a wrong conclusion, so it is important not to focus solely on one change.

Both are economic factors that are based upon economic changes.

Market makers and economists rely upon both indicators to arrive at decisions or forecast any significant future changes in the economy.

• Leading indicators give a heads-up or a red flag for economists and traders regarding a major market shift.
• Lagging indicators serve as proof of a pattern or trend followed by the economy over some time.
• Both indicators depend on the collated data available in the market through qualified sources.

The followings are the key differences:

• Leading indicators focus on the future situation of the economy, whereas lagging indicators focus on the past movements of the economy.
• Leading indicators tend to change before a change in the economy, whereas lagging indicators tend to change after a change.
• The accuracy of a leading indicator cannot be guaranteed; however, the accuracy of a lagging indicator can be relied upon.
• Leading indicators predict any future movements in the markets. On the contrary, monitoring lagging indicators occurs after the movements in the market.
• Leading indicators are input-oriented, whereas lagging indicators are output-oriented. This means that leading indicators are hard to measure, whereas lagging indicators are easy to measure.
