Stocks rose around the world on Tuesday as investors shrugged off indicators pointing to more economic troubles in Europe and the U.S. and hoped the Federal Reserve will act to keep the U.S. from sliding back into recession.
Trading is expected to remain volatile this week as markets await a key speech by U.S. Federal Reserve Chairman Ben Bernanke during an annual economics conference in Wyoming on Friday.
The Fed already pledged to maintain its super-low interest rates until at least 2013, but some economists are calling for a third round of massive bond-buying to pump money into the faltering U.S. economy.
Major European stock markets ended the day in positive territory, although gains were less pronounced than earlier in the day. Britain's FTSE 100 rose 0.7 percent to 5,129.4 points. Germany's DAX and France's CAC-40 both gained 1.1 percent to 5,532.3 and 3,084.3, respectively.
Wall Street traders were also in an optimistic mood, with the Dow Jones Industrial Average rising 1.7 percent to 11,042.6 and the broader S&P 500 adding 2 percent to 1,146.8.
The increase _ the second in a row for most major indexes _ came despite negative economic indicators both in the U.S. and in Europe, signaling how high hopes have risen on new action from the Fed.
Figures published by the U.S. Commerce Department showed that the number of Americans who bought new homes fell for the third straight month in July, putting them on track to finish this year as the worst since records began half a century ago.
Sales of new homes fell nearly 1 percent in July to a seasonally adjusted annual rate of 298,000. The figures underline how high unemployment and the plunging stock markets in recent weeks are deterring consumers from making big investments.
Economic indicators published in Europe, meanwhile, showed that failing efforts to resolve the eurozone debt crisis are cutting into economic activity and sentiment in the currency union's core.
Markit's composite purchasing managers index for the eurozone was unchanged at 51.1 in August, signaling stagnation in the manufacturing sector and hardly any growth in the services sector.

Output in Germany expanded at its weakest rate since the eurozone's largest economy began to recover two years ago, the index showed.
A key survey of economic sentiment brought more bad news out of Germany. The ZEW survey showed that investor expectations for the next six months are at their lowest level since December 2008, dropping to minus 37.6 points from minus 15.1 in July, below the indicator's historical average of 25.9 points.
Germany, which weathered the financial crisis much better than most other developed nations, has seen its stellar growth slow amid increased worries about the cost of bailing out weak eurozone nations.
Investors are getting more concerned about a second rescue package for Greece, as the currency union's 17 members remain locked in discussions about a Finnish deal to get cash collateral for its loan contributions.

Earlier in the day, Asian markets closed higher, tracing gains on Wall Street Monday.
Japan's Nikkei 225 rose 1.2 percent to close at 8,733.01, and Hong Kong's Hang Seng gained 2 percent to 19,875.53. South Korea's Kospi jumped 3.9 percent to 1,772.39.
