The FTSE 100 opened flat on Friday morning as investors showed caution following some mixed comments from US politicians regarding the 'fiscal cliff'.Markus Huber, head of German HNW trading at ETX Capital, said: "European equities are trading little changed this morning despite less encouraging news out of Washington where a deal put to the Republicans by the Democrats received a frosty reception and showed that the parties might actually be further apart than many had hoped." He said that this leaves"a big question mark if a deal will be reached soon."In spite of saying on Wednesday that he was "optimistic" about a deal being made on the 'fiscal cliff', US Republican Speaker of the House John Boehner quashed hopes yesterday by saying that "there is a real danger of going off the fiscal cliff" unless Democrats "get serious about real spending cuts".ETX Capital's Huber said: "The lack of a deal to avoid the fiscal cliff not only poses problems to US businesses [...] but also traders and investors alike are finding it more difficult dealing with the ongoing wrangling as quick shifts in sentiment [...] can lead to erratic short-term moves, which in turn is keeping more and more traders on the sidelines until the situation what the fiscal cliff is concerned is becoming clearer." In domestic news, UK consumer confidence measured by GfK surged to an 18-month high in November, rising to -22 from -30 the month before. Consensus estimates were for no change. There's plenty of other economic data for investors to digest today, including: Eurozone unemployment rate figures; Eurozone inflation; Canadian GDP and US personal consumption expenditure. Meanwhile, today will also see the German parliament vote on the latest Greek rescue package.
