Goldman Sachs and JP Morgan are effectively kicking off the third quarter reporting season in the US, along with United Health and Johnson & Johnson which have also reported.
Neil Wilson, chief markets at Markets.com, said: "Once again the consumer is proving more resilient than anyone dare credit.
"JPMorgan delivered on both the top and bottom line in the third quarter, with its earnings update boding well for US large cap banks, although Goldman Sachs missed its expected [earnings per share] number.
"It also indicates decent consumer strength that suggests retailers, consumer staples are set up well for this season.
"Broadly we can say Q3 earnings season is off to a solid start with three Dow components reporting better-than-expected numbers and just Goldman Sachs undershooting just."
He said the Dow Jones index was expected to open 100 points or so higher.
