The stock market has entered its worst 10-day stretch of the year historically

The stock market has entered its worst 10-day stretch of the year historically, per CNBC.

"The weak start to September does not bode well for the bullish seasonality scenario that we highlighted entering the month. The S&P 500 dropped 1.27% over the first 10 sessions of September, which is well below the average first 10 days of September return of -0.36%," Bank of America technical analyst Stephen Suttmeier said in a Tuesday note.

"The S&P 500 continues to struggle over the last 10 sessions of the month of September, particularly when the first 10 days of the month are below average," Suttmeier said.

"October has its share of big down days, but these down days often provide an opportunity for dip buyers ahead of better seasonality from November through January," Suttmeier said.
