UK stocks were registering only slight losses on Thursday morning as markets managed to hold on to yesterday's impressive gains following the New-Year's-Day agreement to avert the fiscal cliff in the US.Providing some support early on was the China non-manufacturing purchasing managers' index which rose from 55.6 to 56.1 in December, "providing yet more evidence that the turnaround of the Chinese economy is gaining pace with stronger economic growth likely in the months ahead," said Markus Huber, the head of German HNW trading at ETX Capital.The FTSE 100 surged by 2.2% on Wednesday, the first trading day of the 2013, as investors reacted to the deal by US politicians to allow some tax increases on America's wealthiest workers and delay specifics on spending cuts by two months."The inability of congress to approach both the spending cuts element of the fiscal cliff, along with the impending debt ceiling has set up a second deadline around the end of February and beginning of March," said research analyst Joshua Mahony from Alpari. "This time it appears clear that the Republicans will have the upper hand in negotiations whereby their threat to veto any deal to further delay spending cuts or fail to agree on a debt ceiling extension, would likely see a greater level of strength in negotiations. Subsequently there is likely to be even more heated debate in the coming months with the threat of default being primary on the agenda, rather than simply higher taxes in the short term."FTSE 100: Next on shopping lists early onRetailer Next jumped in the opening hour after saying that its full-year results would come in towards the top of expectations.
