Economic and Market Indicators for Recession and Crisis Risk

Article Quant Q&A · Author: SDReyes
Read the original

Summary

The document collects candidate indicators for assessing recession or crisis risk. It describes labor market measures, including nonfarm payroll changes and weekly unemployment claims, alongside quarterly GDP growth and the Purchasing Managers’ Index. The responses compare their potential strengths and weaknesses: payrolls offer a broad employment measure but arrive with a lag, claims are more frequent but noisy, GDP directly measures economic output but is quarterly, and PMI can provide an earlier signal while relying on subjective survey responses.

A second response points to research on collective stock movements as a possible warning signal for market crashes. The proposed measure tracks the share of stocks moving in the same direction, interpreting unusually broad co-movement as market mimicry or panic. The document offers these ideas as possibilities rather than a validated forecasting system. It gives no comparative accuracy results or operational thresholds, and notes that turning the co-movement finding into a usable indicator may be difficult.

Key ideas

  • Payroll changes, unemployment claims, GDP growth, and PMI offer different views of economic conditions and arrive at different frequencies.
  • Weekly jobless claims are timely but can be noisy, while GDP is direct but reported quarterly.
  • PMI may lead other indicators, though it depends on subjective survey responses.
  • Broad same-direction stock movements are proposed as a possible sign of collective panic before crashes.
  • The document presents candidate signals without establishing their forecasting accuracy.

A Bit broad of a question, although here are a few ideas:

- Non Farm Payroll rate of change This is produced by the Bureau of labour statistics, and tracks total employed persons. Ideally one would seek the change in payrolls to view the health of the job market for a given month.

pros:

- large sample size.

cons:

- there is a bit of lag compared to the jobless claims indicator.

- Jobless Claims This is produced by the Department of labour and includes total applications for unemployment insurance.

pros:

- produced weekly

cons:

- very volatile and noisy

- GDP growth This is produced by the BEA and includes GDP growth with GDP defined as: GDP = Consumption + Investment + Government Expenditure + Trade Balance

pros:

- literally measures US economic growth

cons:

- produced quarterly there fore is a lagging indicator

- PMI (Purchasing Manager's Index) A measure of Purchasing manager's sentiment, generally speaking a PMI<50 is indicative of recession. The PMI is reported by the Institute for supply management.

pros:

- leading indicator

cons:

- very subjective reporting

I recently stumbled over an interesting study related to this question: Yaneer Bar-Yam et al. from the New England Complex Systems Institute (NECSI) published a study in 2011 that used "measures of collective panic" to "predict economic market crises". To cite a report about the paper:

> [...] Research analysts have found [that] high levels of collective stock movements - or market mimicry - tend to precede crashes, which suggests that measuring the mimicry level of the market could provide significant advance warning of an impending stock market crash. [...] The researchers constructed a model of this mimicry to obtain co-movement data, which is the percentage of stocks that move in the same direction. [...] When substantially more than half of the stocks move in the same direction, this co-movement indicates higher levels of mimicry."

Personally, I think the results look interesting indeed, although it might be difficult to build an indicator out of these findings.

Anyway, the paper can be found at: https://arxiv.org/pdf/1102.2620.pdf
