London's FTSE 100 Index remained in positive territory after yesterday's sharp gains despite ongoing fears over plans to scale back America's bond-buying programme.
The FTSE 100 rose 2.1 points to 6449, having risen nearly 1% on Thursday on upbeat economic data from China and Europe.
America's Dow Jones Industrial Average ended a six-day losing streak overnight, rising by 66 points, while the Nasdaq climbed 1.1% despite seeing trading halted for three hours due to a technical glitch.
But there remain concerns over the timing of US Federal Reserve plans to taper quantitative easing (QE) after it failed to shed any light on them in this week's July meeting minutes.
Shavaz Dhalla, t rader at Spreadex, said: " The trepidation is partly justified as officials themselves have not come to a unified agreement regarding the longevity of the stimulus measures."
Among stocks, Carpetright was under pressure in the FTSE 250 Index after it confirmed it was one of six firms contacted by the Office of Fair Trading (OFT) as part of an investigation into misleading sale prices.
The group's shares fell 2% or 10.5p to 660p as it said it was co-operating fully with the OFT and would respond to its concerns in due course.
CPP plunged another 15% - down 2.25p to 12.5p - after yesterday's 27% tumble as the City regulator said the group and 13 high street lenders will fork out up to £1.3 billion in compensation for mis-sold credit card and identity theft protection.
The group remained firmly in the spotlight as its majority shareholder Hamish Ogston showed little remorse for the scandal.
