Recently, someone asked me how to distinguish between the Small Non-Farm Payrolls and the Large Non-Farm Payrolls. I found that many people are actually confused. Simply put, these two data points have completely different impacts on the U.S. stock market.

First, let's talk about the Small Non-Farm Payrolls, officially known as the ADP National Employment Report. This report is released by ADP, a payroll processing company, based on their client data, usually on the first Wednesday of each month. The key point is that it only reflects new employment in the private sector; government employment data is not included. So, essentially, the Small Non-Farm Payrolls is a prelude, used by many investors to guess what the big Non-Farm Payrolls will look like.

The truly significant data is the Large Non-Farm Payrolls. This is the official data released by the U.S. Bureau of Labor Statistics (BLS), typically on the first Friday of each month. The Large Non-Farm Payrolls cover all non-farm employment changes in both the private and government sectors, including new jobs added, unemployment rate, average hourly earnings, and more. This is the main basis for Federal Reserve interest rate decisions and market expectations.

The biggest difference between the two lies in authority and coverage. The Small Non-Farm Payrolls is just a sample estimate, often differing from the final Large Non-Farm Payrolls data. The Large Non-Farm Payrolls is an official statistic, more comprehensive, and the market pays much more attention to it.

In terms of actual impact on U.S. stocks, the Small Non-Farm Payrolls may cause short-term volatility after release, but due to its lack of authority, this volatility is usually limited. The Large Non-Farm Payrolls, on the other hand, is different. If employment data exceeds expectations, indicating a strong economy, U.S. stocks usually rise. Conversely, if the data falls short, it can heighten fears of an economic slowdown and may trigger a stock market decline.

Therefore, the Large Non-Farm Payrolls is the real market-moving indicator. The Small Non-Farm Payrolls is just an early reference, but ultimately, the market reacts most strongly to the actual numbers and performance of the Large Non-Farm Payrolls. If you want to buy the dip or hedge risks, you must pay close attention to the release time and actual figures of the Large Non-Farm Payrolls.
