After a week of losses, investors are expected to jump in and buy stock at their lower prices today, despite widespread concerns about the economic stability of the Eurozone. City sources predict the FTSE 100 will open around 13 points higher than yesterday's close of 6,672.37.The renewed worries about the euro-area countries came mainly as a result of the parent company of Portuguese bank Banco Espirito Santo (BES) announcing its intention to postpone the repayment of a debt. BES, the second-largest lender in Portugal, saw its stock drop sharply yesterday before the suspension of trading of its shares and prompted the country's benchmark PSI 20 Index to suffer its biggest seven-day drop since August 2011.

"This is because none of the underlying problems that served to create the crisis have been dealt with, namely the sovereign debt feedback loop between banks and the governments they fund," he explained. "The crisis in Portugal is a direct consequence of this failure, along with an almost shocking complacency on the part of investors who have driven bond yields in countries like Greece, Portugal, Spain and Italy to, in some cases, record lows."
