LONDON -- Global markets fluctuated Wednesday as investors weighed poor economic data against expectations that the European Central Bank will announce a plan to support financially weak countries in the 17-member eurozone.
ECB President Mario Draghi is expected to reveal on Thursday the details of a new bond-buying program intended to bring down the high borrowing costs of Spain and Italy. The move would go a long way to stabilize Europe's financial crisis -- in fact, expectations of the move have buoyed markets for weeks.

But analysts warn the plan's success may yet face challenges. To be eligible for the central bank's help, for example, countries would likely have to accept conditions on their budget policies, which many governments would be reluctant to do.
"Expectations for Thursday's ECB meeting are high, perhaps too high," said Marie Diron, senior economic adviser at Ernst & Young.
Europe's economy also remains fundamentally weak. A survey of the eurozone's services sector on Wednesday showed the sector continued to contract in August. The so-called purchasing managers' index fell more than earlier estimated, suggesting the currency bloc is headed for a sharp drop in GDP in the third quarter.

Investors will look ahead to Friday's U.S. payrolls data for signs that the world's largest economy is recovering.
Continued signs of weakness in the U.S. economy may help persuade the Federal Reserve to announce new action after its meeting next week.
"If we don't see any good, positive catalyst, investors will be very reluctant to buy stocks at this point. We are waiting for the ECB, U.S. jobs data and other major U.S. economic data," said Jackson Wong, vice president at Tanrich Securities in Hong Kong.
Other analysts cautioned that central bank actions may be too little to protect markets from volatility through the end of the year.
"Whether upcoming ECB and Fed actions will be sufficient to prevent an escalation in risk aversion is debatable especially as markets have already priced in a lot of potential action," analysts at Credit Agricole CIB in Hong Kong said in a market commentary.
