Why did the unexpected non farm payroll data trigger a sharp drop in the US stock market yesterday? Yesterday (after the non farm payroll announcement), there was a significant adjustment in the US stock market, with the Dow Jones Industrial Average falling 1.39%, the S&P 500 falling 1.47%, and the Nasdaq falling 1.63%. The overall market showed a typical reaction of "positive data but negative stock market". The core contradiction is not "economic downturn", but "the economy is too strong", which has significantly lowered market expectations for the Fed's interest rate cuts. 1、 Core Highlights of Non Agricultural Data (May Data) Newly added non-agricultural employment: 172000 people (expected to be 130000, significantly exceeding expectations) Unemployment rate: 4.3% (as expected) Average hourly wage compared to the same period last year: 3.4% (previously 3.6%, with a slower growth rate but still at a high level) The overall data conveys a signal that the labor market is still strong, with employment significantly better than expected, wage stickiness remaining, stable unemployment rate, and no obvious signs of weakening. 2、 Core logic chain: Why does the stronger the non farm sector, the more significant the decline in the US stock market? Non farm payroll exceeds expectations → Strong job market, active recruitment by enterprises, and strong demand for labor force. Strong employment → Consumer demand supports stable household income, and consumer resilience remains strong. Strong consumption → The pressure of inflation cooling has increased, and the demand side is strong. Inflation stickiness may rebound, making it more difficult to cool down. Inflation pressure → Decreased expectation of interest rate cuts, market timing of interest rate cuts may decrease, and even reduce the number of expected interest rate cuts. Expectations of interest rate cuts decrease → US bond yields rise+US dollar strengthens, funds flow back into the bond market and the US dollar, and safe haven funds flow into US dollar assets. The discount rate of overvalued technology stocks has increased, and the valuation pressure has significantly increased (especially for growth technology stocks). The final result is that the risk appetite for short-term decline in the US stock market has decreased, and market sentiment has weakened. The stronger the non farm sector, the harder it is to cut interest rates; the harder it is to cut interest rates, the greater the pressure on US stock valuations 3、 Key contradiction points This decline is not due to "economic downturn leading to stock market decline", but "the economy is too strong, causing the market to worry that interest rate cuts will come later". The valuation of US stocks, especially technology stocks, is highly dependent on a low interest rate environment. Once interest rate expectations rise and the cost of capital increases, the valuation center will shift downwards, and stock market liquidity will tighten in the short term. 4、 Actual market reaction yesterday The three major US stock indices fell across the board, with technology stocks leading the decline. The yield of 10-year US Treasury bonds has significantly increased (+7.5bp to 4.35%). The US Dollar Index (DXY) rose 0.46%. This validates the transmission path of "strong data → strong US dollar → high returns → suppressed valuation". The current market is in a sensitive stage where 'good data equals bad news'. Subsequent attention should focus on speeches by Federal Reserve officials, inflation data (CPI/PCE), trends in US bond yields, and changes in global risk sentiment. Every time the expectation of interest rate cuts is lowered, it may continue to exert pressure on high valuation sectors.
