The article states that Peloton's stock price is up 6.92% to $9.55 due to the softer-than-expected CPI report, which showed slowing inflation in May. Lower inflation rates can make Peloton's products and subscription services more affordable for consumers, encouraging more individuals to invest in their fitness equipment or sign up for their digital workout programs. This can drive revenue growth for the company, positively impacting its stock price in the short term.
