World stock markets have started the new year strongly, with investors cheered by strong US manufacturing data. Although the most recent data points to a recovery in the world's largest economy, job data due this week could cool things somewhat when it is expected to reveal little in the way of job growth. In the UK investors will likely have grounds for optimism when the London Stock Exchange opens today with a Deloitte report showing confidence among chief financial officers revived in the final quarter of 2010. The latest European manufacturing purchasing managers' index also showed that factory activity improved for the third consecutive month in December across the eurozone.
