Non-Farm Payroll (NFP) Model Forecast – December 2015

This article presents the Trader Edge aggregate neural network model forecast for the December 2015 non-farm payroll data, which is scheduled to be released tomorrow morning at 8:30 AM EST.

Non-Farm Payroll (NFP) Model Forecast - December 2015

The Trader Edge aggregate NFP model represents the average of three neural network forecasting models, each of which employs a different neural network architecture.  Unlike expert systems, neural networks use algorithms to identify and quantify complex relationships between variables based on historical data.  All three models derive their forecasts from seven explanatory variables and the changes in those variables over time.

The table in Figure 1 below includes the monthly non-farm payroll data for two months: November and December 2015.  The November data was released last month and the non-farm payroll data for December 2015 will be released tomorrow morning at 8:30 AM EST.

The model forecasts are in the third data row of the table (in blue).  Note that past and current forecasts reflect the latest values of the independent variables, which means that forecasts will change when revisions are made to the historical economic data.

The monthly standard error of the model is approximately 76,600 jobs.  The first and last data rows of the table report the forecast plus 0.5 standard errors (in green) and the forecast minus 0.5 standard errors (in red), respectively.  All values are rounded to the nearest thousand.  If the model errors were normally distributed, roughly 31% of the observations would fall below -0.5 standard errors and another 31% of the observations would exceed +0.5 standard errors.

The actual non-farm payroll release for November 2015 is in the second data row of the table (in purple).  The consensus estimate (reported by Briefing.com) for December 2015 is also in the second data row of the table (in purple).  The reported and consensus NFP values also include the deviation from the forecast NFP (as a multiple of the standard error of the estimate).  Finally, the last column of the table includes the estimated changes from November 2015 to December 2015.

Model Commentary

The aggregate neural network model forecast for December is 261,000, which is up 34,000 jobs from last month's revised forecast of 227,000, reflecting an increase in the strength of the employment environment during the month of December. The Briefing.com consensus estimate for December is 200,000, which is 11,000 lower than the November NFP data (211,000), suggesting a very slight weakening in the employment environment.

The actual November data was slightly below the revised November forecast (-0.21 S.E.) and the consensus estimate for December is materially below the December model forecast (-0.80 S.E.). If the actual December data is close to the December forecast of 261,000, it would represent a significant upside surprise tomorrow.

If we ignore the large NFP outliers, there had been a gradual and sustained positive trend in the employment data from mid-2012 through late 2014. The trend is easier to see in the forecast data due to fewer outliers. The positive trend in the model forecasts definitely reversed in early 2015, but the recent increasing model forecasts may indicate a slight strengthening over the past few months.

Summary

Basic forecasting tools can help you identify unusual consensus economic estimates, which often lead to substantial surprises and market movements.  Identifying such environments in advance may help you protect your portfolio from these corrections and help you determine the optimal entry and exit points for your strategies.

In the case of the NFP data, the monthly report data is highly variable and prone to substantial revisions.  As a result, having an independent and unbiased indicator of the health of the U.S. job market is especially important.
