Equities on both sides of the Atlantic advanced after a report showing strong US retail sales bolstered optimism about the outlook for corporate profits and the economy, while concern about China's currency depreciation eased.
A Commerce Department report showed US retail sales rose 0.6 percent in July. Sales in June were unchanged, revised from the 0.3 percent drop initially reported.
The data helped bolster expectations the Federal Reserve will raise interest rates as early as September.
"US consumers are out there spending and driving a large part of economic growth," Luke Tilley, chief economist at Wilmington Trust in Wilmington, Delaware, told Reuters. "It means the Fed will be confident that the economy is still on fairly strong footing and supports the view that they could raise rates in September."
Tuesday's unexpected currency devaluation by China's central bank, which is trying to stoke the nation's pace of economic growth, initially prompted bets US policy makers might delay a rate increase. The People Bank's of China on Thursday pledged support for the yuan, saying there was no reason for the depreciation to continue.
