London open: Markets flat ahead of Eurozone data

UK stocks opened flat on Tuesday morning ahead of some key economic indicators from the Eurozone.On today's agenda, there will be unemployment figures in Italy, German factory orders as well as consumer confidence, jobless and retail sales data for the Eurozone as a whole.Market analyst Craig Erlam from Alpari said to expect increased levels of volatility this week ahead of the start of fourth-quarter reporting earnings season. "The last couple of earnings seasons have been overshadowed by events in the Eurozone and the US. What we've seen over the last six months is a stock market rally that has largely ignored company performances and instead been driven by unlimited central bank stimulus and an increase in risk appetite and one disaster after another is averted."We're now going into an earnings season with sky high stock prices, a recent history of lower revenues with profits driven by cost cutting and low expectations. With nothing else to distract us, this could be the perfect recipe for heightened volatility in the markets and a potential correction in equity prices that has been long overdue," Erlam said.Investors will be keeping close eyes on decisions from central banks this week. Neither the Bank of England (BoE) nor the European Central Bank (ECB) are expected to make a move this week.
