Dow Drops 2.4% in First 10 Trading Days of September, Worst Start Since 2008
nashnova research
The Dow fell 2.4% in the first ten trading days of September, its worst such stretch since 2008; the S&P 500 and Nasdaq slid in tandem, signaling a broad cooldown in market sentiment.
How bad is the Dow's September start?
The Dow has dropped 2.4% since September began — per Dow Jones Market Data, that is the worst first-ten-session September since 2008.
This means → the last time September opened this poorly was the year of the global financial crisis — a historically rare weak signal.
In plain terms = September is only half over, and the Dow is already at its weakest start in sixteen years.
Are the S&P 500 and Nasdaq holding up?
The S&P 500 fell roughly 1.4% over the same span, its worst September start since 2020.
The Nasdaq Composite also dropped about 1.4%, its weakest September opening since 2023.
This means → no single index is the outlier — all three are sliding together, pointing to broad-based selling pressure across sectors.
What comes next?
All three benchmarks are down, and each comparison points to a historically unusual weak open.
This reflects a shift in market mood from "cautious" to "defensive."
Whether the indices can recover in September's remaining sessions is the key test of whether this weakness is a short-term dip or the start of a larger turn.
