BEIJING: Global stocks rose again Tuesday on optimism Britain will vote to stay in the European Union, as investors awaited an economic report by the head of the US Federal Reserve.

KEEPING SCORE: London's FTSE 100 edged up almost 0.1 percent to 6,204 while Germany's DAX rose 0.6 percent to 10,019 and France's CAC 40 advanced 0.6 percent to 4,368.

Wall Street looked set for more gains, with futures for the Dow Jones industrial average up 0.4 percent and those for the Standard & Poor's 500 index up 0.5 percent.

BREXIT: Opinion polls and betting markets indicate that Britons are more likely to vote to remain in the European Union in a referendum Thursday.

Many believe a departure, known informally as Brexit, would hurt the British and European economies and possibly encourage other countries to leave. Uncertainty about the outcome has weighed on global markets. The vote is expected to be close.

FED WATCH: Federal Reserve Chair Janet Yellen is to give a semiannual report on the US economy to the Senate. The Fed suggested in a statement after its latest policy meeting that it needs a clearer economic picture before resuming interest rate hikes it began in December.

Some economists think a July increase is possible if the job market rebounds from a dismal May and financial markets remain calm after Britain's EU vote.

ANALYST'S QUOTE: "Investors will likely continue to focus on the calculus surrounding the UK's EU referendum," Citigroup analysts said in a report. "There will also be interest in tonight's congressional testimony by Fed Chair Yellen."
