The market's downward move marked the second sluggish day after a five-day streak of records sparked by hopes for a major tax cut prompted by President Donald Trump's comments last week.

Kraft Heinz and Unilever were both up around nine percent after Unilever rejected a $143 billion bid from the US firm that it said "fundamentally undervalues" the company.
