European equities closed higher on Wednesday afternoon, as business activity in the euro zone expanded at its fastest pace since June 2011 in January, with stocks in Greece staging a rally on the back of a media report suggesting the maturity of loans to Athens could be extended.
The pan-European index provisionally closed higher by 0.1 percent at 1,272.28 points.
Bloomberg reported that the next bailout for Greece might extend the maturity of its loans to 50 years from 30 years, and cut the interest rate on some previous loans. Greek bond yields were sharply down following the report.
Other European markets focused on data from the U.S. which showed that private companies in the U.S. created 175,000 new positions in January. The figure was a bit lower than expected but in keeping with the pace of job creation over the past two years.
"Nothing changed in December or January fundamentally," Moody's economist Mark Zanki told CNBC after the data. "The economy is still improving."
The ADP data from the U.S. comes ahead of Friday's non-farm payrolls data for January. Investors will be watching the data closely to gauge the strength of the U.S. economy and predict the Federal Reserve's next move, a week after it announced it would further reduce its monetary stimulus program by another $10 billion a month to $65 billion.
Meanwhile in Europe, euro zone data showed business activity grew for the seventh consecutive month in January, offering a boost to markets.
