However, reports of a Financial Conduct Authority (FCA) investigation into insurance policies sent insurance stocks reeling.Sentiment was also dampened by economic data which showed that the current account deficit in the UK remained close to a record high in the fourth quarter of 2013, surprising analysts who had expected a big reduction.The FTSE 100 was trading just 0.03% higher at 6,590 by midday, coming off a high of 6,631.34 reached mid-morning.Chinese stimulus speculationLi, speaking at a government meeting in Shenyang, reportedly said that policymakers "should launch well-targeted, effective measures one after another according to our tasks stated in the Government Work Report". He said that the government should not overlook "downward risks" to the economy and has the "ability, confidence and conditions to make sure the economy runs within a reasonable range"."A targeted fiscal stimulus programme was carried out last year in similar circumstances, when slowing growth drove fears that the country would not hit its 7.5% growth target. These efforts worked then and I have little doubt that they'll work again if carried out this year," said Market Analyst Craig Erlam from Alpari.Insurers tank on FCA reportsAccording to The Telegraph, the FCA is set to announce it will check 30m insurance policies worth £150bn over concerns customers were exploited. The regulator will next week say it is looking at pensions, endowments, investment bonds and life insurance policies sold in the UK sold between the 1970s and 2000.Resolution dropped 15% on the news, while Phoenix plummeted 23%.
