 Global stock markets rose Wednesday following a surge on Wall Street triggered by a Federal Reserve pledge to keep interest rates super low for the next two years to help the ailing U.S. economy. 
  
 Oil prices rose to near $82 a barrel, while the dollar slid against the yen and the euro. European shares were slightly higher in early trading after a restorative rally in Asia. 
  
 Britain's FTSE 100 index rose 0.2 percent to 5,177.23. Germany's DAX was 0.9 percent higher at 5,977.73 while the CAC-40 in Paris dipped 0.3 percent into negative territory at 3,153.01. 
  
 Meanwhile, Wall Street appeared set to capitulate after sizable gains the day before. Dow Jones industrial futures drooped 134 points, or 1.2 percent, to 11,060 and broader S&P 500 futures gave up 12.90 points, or 1.1 percent, to 1,158.80. 
  
 On Tuesday, the Dow finished with a 429-point gain after the Fed said it would keep its key interest rate at a record low of nearly zero through the middle of 2013. The index dived 634.76 points the day before after Standard and Poor's cut the U.S. government's credit rating, sending shock waves through global markets. 
  
 Analysts warned investors to brace for more sharp swings in markets amid a dearth of signs of improvement in the global economy. 
  
 "There is a lot of fear and uncertainty in the market, and negatives will add to that. So if we see an increase in unemployment from the U.S., that is going to cause an increase in volatility," said Samuel LeCornu, portfolio manager at Macquarie Funds Group in Hong Kong. 
  
 Japan's Nikkei 225 index climbed 1.1 percent to close at 9,038.74 following a 7.6 percent loss in the last three days. Export shares, however, continued to struggle because of the strong yen, which hurts the country's export-driven economy by reducing the value of foreign earnings. 
  
 Honda Motor Co. lost 2.2 percent and rival Toyota Motor Corp. was down 0.9 percent. Consumer electronics giant Sony Corp. fell 2.2 percent.

 South Korea's Kospi, which at one point Tuesday plummeted nearly 10 percent, added 0.3 percent to 1,806.24. 
  
 Gains in Asia were broad-based, with banking shares among the key movers. Australia's Westpac Banking Corp. was 4.6 percent higher and National Australia Bank Ltd. soared 6.1 percent. Industrial and Commercial Bank of China, the world's biggest bank by market value, gained 1 percent.

 Worries about the U.S. economic recovery have been building since the government said that economic growth was far weaker in the first half of 2011 than economists expected. In a reversal of earlier forecasts, economists now believe there is a greater chance of another U.S. recession because the economy grew much more slowly in the first half of 2011 than previously thought. 
  
 The manufacturing and services industries barely grew in July. The unemployment rate remains above 9 percent, despite the 154,000 jobs added in the private sector in July. 
  
 Economies across the globe are also struggling. 
  
 Concerns are growing that Spain or Italy could become the next European country to be unable to repay its debts. High inflation in less-developed countries, which have been the world's main economic engine through the recovery, is another concern. China's inflation rose to a 37-month high in July.

 Trading was once again marked by sharp moves on heavy volume. For a fifth straight day, the Dow industrials fluctuated in a range of more than 400 points. 
  
 “What you’re seeing is a very short-term, direction-oriented market,” said Eric Kuby, chief investment officer of North Star Investment Management Corp in Chicago. 
  
 Worries about the strength of French lenders, including Societe Generale, triggered a selloff in European and U.S. banks. Rumors about SocGen’s financial health, which the bank denied, sent its shares tumbling 14.7 percent. 
  
 An index of European banks dropped 6.7 percent and the KBW index of U.S. bank stocks slid 4.9 percent as fear grew of a possible contagion of any French crisis. Bank of America Corp lost 10.9 percent to $6.77 and Goldman Sachs slid more than 10 percent to $110.34. 
  
 The Dow Jones industrial average lost 519.83 points, or 4.62 percent, to 10,719.94. The S&P 500 fell 51.77 points, or 4.42 percent, to 1,120.76. The Nasdaq Composite dropped 101.47 points, or 4.09 percent, to 2,381.05. 
  
 Wednesday’s drop came a day after stocks rallied on the Federal Reserve’s pledge to keep interest rates near zero for at least two more years. 
  
 Even after Tuesday’s snap-back rally, the S&P 500 is down almost 18 percent from its 2011 closing high set April 29. 
  
 The losses came against the backdrop of recent weak U.S. economic data, the United States losing its triple-A credit rating from Standard & Poor’s and the inability of lawmakers to address worries that another recession may be on the way. 
  
 About 15.1 billion shares traded on the New York Stock Exchange, NYSE Amex and Nasdaq, almost double the year’s estimated daily average of 7.8 billion. 
  
 Volume once again spiked in the last hour of trading, and the market closed near its session lows. Of late, overleveraged investors with losses on their books have been forced to sell shares near the end of the day. 
  
 “Between 3 and 3:20 (p.m.) you have people getting margin calls, and on days like today there’s some nervousness about what those calls will look like,” said Andrew Frankel, co-president of Stuart Frankel & Co in New York, referring to the volatility of the final hour of trading. 
  
 Slides in the value of stocks may increase the cash needed in margin accounts, which can spark further selling.

 Dow component Walt Disney Co dropped 9.1 percent to $31.54 a day after the entertainment company’s quarterly results failed to reassure investors that it could do well in a weak U.S. economy. 
  
 After the closing bell, Cisco Systems Inc’s shares jumped nearly 12 percent after its quarterly results edged past Wall Street’s scaled-back expectations. 
  
 Declining stocks outnumbered advancing ones during the regular session on the NYSE by a ratio of more than 8 to 3, while on the Nasdaq, almost five stocks fell for every one that rose. |||||

Global stocks were up early today following an uptick on Wall Street in the wake of the Fed's pledge to keep interest rates low. But it wasn't clear if the rebound would hold. Asia rates climbed and modest hikes marked Britain's FTSE 100 index (up .2%) and Germany's DAX (up .9%), though the CAC-40 in Paris was down .3%, and the the Euro Stoxx 50 index of euro zone blue chips opened higher but was down .4% by mid-morning. Falling futures indicated possible trouble ahead still for Wall Street. Futures for the Standard & Poor's 500 were down 1% and Down Jones futures were off .9%, Reuters reported early today. Analysts warned investors to steel for more wild rides yet to come in the market. "There is a lot of fear and uncertainty in the market, and negatives will add to that. If we see an increase in unemployment from the US, that is going to cause an increase in volatility," one analyst told AP.
