This article presents the Trader Edge aggregate neural network model forecast for the August 2016 non-farm payroll data, which is scheduled to be released tomorrow morning at 8:30 AM EDT.
Non-Farm Payroll (NFP) Model Forecast - August 2016
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: July and August 2016. The July data was released last month and the non-farm payroll data for August 2016 will be released tomorrow morning at 8:30 AM EDT.
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 82,000 jobs. The first and last data rows of the table report the forecast plus one standard error (in green) and the forecast minus one standard error (in red), respectively. All values are rounded to the nearest thousand. If the model errors were normally distributed, roughly 16% of the observations would fall below minus one standard error and another 16% of the observations would exceed plus one standard error.
The actual non-farm payroll release for July is in the second data row of the table (in purple). The consensus estimate (reported by Briefing.com) for August 2016 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 July to August 2016.
The aggregate neural network model forecast for August is 258,000, which is almost unchanged (+6,000) from last months forecast of 252,000, reflecting a static employment environment during the month of August. The Briefing.com consensus estimate for August is only 180,000, which is down sharply (-75,000) from the actual July NFP data (255,000).
The actual July data was almost exactly equal to the forecast (+0.04 S.E.). The consensus estimate for August is materially below the August model forecast (-0.95 S.E.). Given the accuracy of the July forecast, it is unlikely that the actual July data was an outlier. As a result, the significant difference between the August forecast and August consensus significantly increases the likelihood of an upside surprise tomorrow.
I added a new chart recently (Figure 3 below) to make it easier to observe trends in the employment environment. The blue line depicts the model forecasts (including the latest revisions) and is exactly the same as the Forecast NFP line in Figure 2 above. However, Figure 3 also contains a purple line, which shows the 12-month moving average of the NFP model forecasts.
Why plot the moving average of the model forecasts instead of the actual NFP data? Because the actual NFP data is notoriously noisy. The Forecast NFP data more accurately captures the strength of the employment environment and the stability of the data series makes it easier to observe the trend in employment.
We can use the chart below in Figure 3 in two ways to identify the trend in employment. First, we can observe the forecast NFP data relative to the moving average. Observations below the moving average indicate a weakening in employment and vice versa. Second, we can observe the slope of the moving average line. When the moving average line is downward-sloping, employment is weakening and vice versa.
As you can see from the chart in Figure 3, the slope had been negative since early 2015, but recently stabilized and has now turned positive. In addition, the forecast NFP data has been above the moving average for the past four months, which explains the recent slope change. There is no question that the employment environment has strengthened recently.
The consensus NFP estimate for August is significantly below the forecast, which increases the likelihood of a material upside surprise tomorrow. If the actual August NFP data is consistent with the forecast, it would increase the probability of a near-term rate increase by the Fed. As a result, the NFP release tomorrow has important implications for stocks, bonds, currencies, and commodities.
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.
