The episode’s clearest market inflection point is Reddit joining the S&P 500 as traditional energy companies help lift stocks.
The brief
The week’s market story begins with July inflation: headline prices cooled to 3.4%, while core prices rose 2.5% year over year, near their lowest level since 2021.
That inflation mix gives markets a more nuanced signal: overall price growth is easing, but underlying pressures remain part of the economic backdrop investors are tracking.
Traditional energy companies helped push stocks higher, adding a sector-specific force to the broader market developments reviewed in the episode.
Reddit’s addition to the S&P 500 provides a contrasting marker of changing market composition, placing the company inside an index of 500 large U.S.-listed companies.
Taken together, the week’s developments show markets balancing cooling inflation against changing leadership across sectors and companies.
