Sector and data cues today

Today, Ameren stock heads into the open against a backdrop of ongoing attention to US economic indicators and interest-rate expectations, factors that can influence utilities valuations because of their sensitivity to bond yields and capital costs. The real-time economic calendar from Investing.com highlights scheduled releases of macro data and potential central-bank commentary, which can shape expectations for future rate moves and, in turn, the relative appeal of defensive income-oriented sectors such as utilities.
