There are no major UK macroeconomic data releases due, but in the US investors will eye the release of retail sales and inflation data for December at 1330 GMT. Market participants will also turn their attention to the US corporate calendar as earnings season kicks off in usual style with big banks JPMorgan Chase, BlackRock and Wells Fargo all reporting.
"Recent market highs have been based on expectations of higher global growth and increased corporate earnings, so the start of the US earnings season today is a major market event," said analyst Rebecca O'Keeffe at Interactive Investor. "Investors will be hoping that both top line growth and high margins can lead to substantial earnings growth and justify current equity valuations."
On the UK corporate front, the share up-swell was led by GKN, which surged nearly 27% after the company said it has rejected a bid proposal from Melrose Industries and appointed Anne Stevens as chief executive, as it announced plans to separate its aerospace and automotive businesses.
