FTSE 100 Flat as Investors Await US Inflation Data; Balfour Beatty Hits Record High

The FTSE 100 index remained flat on Wednesday as investors waited for US inflation data, which could impact expectations for interest rate hikes.

Despite a lackluster performance from the blue-chip index, midcap stocks outperformed with the FTSE 250 climbing 0.5% to a record high.

Balfour Beatty led the gains among midcaps after raising its annual operating profit forecast due to strong demand for infrastructure projects in the US and UK.
