London open: Stocks rise despite contradictory reports on Spain

- Portugal, Greece and Spain in the spotlight- Markets await economic data from UK and Eurozone- Rio Tinto and Anglo American gain London's FTSE 100 index registered a strong start on Tuesday morning as investors celebrated signs of progress in the Eurozone.Markets finished with just slight gains on Monday despite some better-than-expected US retail sales data and decent third-quarter figures from banking giant Citigroup. Market analyst Craig Erlam from Alpari said this morning: "This just shows that the Eurozone is still at the forefront of everyone's minds this week. The EU summit on Thursday and Friday is all investors seem to care about at the moment. It is not often that we see such positive retail sales data and corporate earnings completely ignored." Portugal has been hit by protests after it revealed its 2013 budget yesterday which includes tax rises and spending cuts and is likely to see the country fall into its third year of recession. Greek Prime Minister Antonis Samaras said in Athens last night that he is confidence that Greece will receive its next tranche of the bailout.The Spanish government is preparing to make a request for aid, according to an article in the Financial Times last night, but is being held back by considerations relating to Germany and Italy. Bloomberg, however, is reporting that Spain's Prime Minister believes that holding out for longer will win the country better terms. What might be construed as similar reports out yesterday, from Dow Jones Newswires, may have weighed on Spanish bonds.Meanwhile, Standard & Poor's has cut its long-term credit ratings for 11 Spanish banks and short-term ratings on four, as is often to be expected after having done the same with the underlying sovereign previously. Markets will be keeping an eye out for a short-term Spanish debt auction scheduled for later this morning, the first issuance since Standard & Poor's (S&P) downgraded the country's debt rating last week to just one notch above 'junk status'.Economic data from home and away is due out today.
