Tuesday's close of US markets was neutral, ahead of a flurry of corporate earnings and significant inflation data.
The Nasdaq fell more than 1%, and the S&P 500 suffered its fifth straight loss.
JP Morgan cautioned that if September inflation comes in at more than 8.3%, stocks could experience a further 5% decline on Thursday.
As investors struggled to gather momentum ahead of a barrage of earnings and the much anticipated inflation report due on Thursday, US markets closed Tuesday with a mixed performance.
The S&P 500 suffered losses for the fifth day in a row.
The Dow Jones Industrial Average, meanwhile, finished the day in the black after rising 200 basis points for a brief period of time.
