During early U.S. trade, the Dow Jones Industrial Average added 0.10%, the S&P 500 index rose 0.26%, while the Nasdaq Composite index climbed 0.51%.
Markets remained jittery amid concerns over the U.S. fiscal cliff, automatic tax hikes and spending cuts due to come into effect on January 1 unless lawmakers can reach an agreement, which could threaten U.S. and global growth.
On Sunday, Greece’s government approved a budget of spending cuts and tax increases for next year, just days after the parliament narrowly approved a EUR13.5 billion austerity package required to secure the country’s next installment of financial aid.
