The S & P 500 is on track for another positive week as investors cheered better-than-expected inflation numbers. The consumer price index rose 8.5% year over year in July, compared to economists’ expectations of 8.7%. Meanwhile, wholesale inflation , as measured by the producer price index, fell 0.5% last month.
