The blue-chip FTSE 100 edged up 0.1% as oil stocks rose. BP was the top FTSE 100 gainer on the back of strong earnings. BP climbed 2.6% after it said it would lift its dividend by 4% and ramp up share buybacks after second-quarter profits rose to $2.8 billion. The domestically focused mid-cap index eased 0.2%, led by building materials seller Travis Perkins and Broker TP ICAP Group, down 2.3% and 4.5% respectively. Travis Perkins fell despite raising its 2021 earnings outlook and announcing a special dividend of 35 pence per share, while TP ICAP dropped after its half yearly revenue slipped 5%.
