DOUBTS LINGER
Investors may be hunting for a bargains, but underlying concern about whether measures can really be implemented to rescue Greece from its debt crisis remained intact, said analyst Woon Khien Chia of the Royal Bank of Scotland in Singapore.
"Nobody wants to take very big positions," she said, adding that even after the basic framework was agreed to rescue Greece, questions have already been raised about who was going to fund the bailout.
Late in October, Euro zone leaders struck a deal with private banks and insurers for them to accept a 50% loss on their Greek government bonds under a plan to lower Greece's debt burden, while asking Greece for severe austerity measures.
They also agreed that the European Financial Stability Facility, a bailout fund, would be leveraged to give it firepower equivalent to about 1 trillion euros ($1.4 trillion).
ECB CUT SUPPORTS
Market sentiment was supported by the European Central Bank's surprise rate cut of 25 basis points on Thursday, the first meeting under new President Mario Draghi. Draghi said the euro zone could enter a "mild recession" later this year.
"The ECB's surprise move to cut rates suggested it took a preemptive move as it forecast growth slowdown, which gave a positive surprise to the market," Credit Agricole's Saito said.
