Britain's top share index steadied on Tuesday after five straight sessions of falls, with miners and financials rebounding as concerns over emerging markets began to ease, Reuters reported. The stabilisation of a recent emerging market sell-off that has roiled global stock markets in the last week offered a chance for some of the shares that have been worst hit to rally off their lows. The FTSE 100 index has lost 4.2 percent since last Tuesday, and posted five straight sessions of losses for the first time since December 2013. The index only saw five straight down days on one other occasion in 2013, in March. Miners gained 0.9 percent on Tuesday and accounted for many of the top blue chip risers, having dropped 5.3 percent since the beginning of last week, supported by a firmer Australian dollar. The FTSE 11 was 20.05 points higher, up 0.3 percent, at 5,670.71 at 0838 GMT, with technical signals also pointing to a rebound after the week's steep falls.
