City sources predict the FTSE 100 will open 13 points higher than Friday's close of 6,739.94, as investors weigh up last week's US jobs data and a mixed performance by Asia stocks overnight. According to Craig Erlam from Alpari, the fact stocks are set to move higher early on "suggests that we're still stuck in a very unusual environment in which investors can't decide what is actually more beneficial for the stock markets, positive fundamentals or more quantitative easing". He continued: "Given that they appear to be rallying off either, I guess at this stage they're not overly bothered. As long as they have an excuse to buy on the dips and continue to benefit from rising share prices, that's all they're concerned about."While it is looking rather light on macro news this week, a number of companies will be putting out important announcements, with a particular focus likely to be on retailers. Ocado, Home Retail Group, Dixons and Associated British Foods (which owns Primark) are all expected to post positives Christmas trading sales. The focus this week will also be on the financial sector. "As we saw in the previous quarter, this is expected to be the best performing sector in this earnings season, which should mean earnings season getting off to a very positive start," Erlam said. "[...] Large amounts of earnings growth is still being driven by cost-cutting, with low levels of lending and smaller margins, among other things, weighing on profits."
