World stocks edged up from this month's 11-month low on Thursday while gold fell sharply as investors took an optimistic view of how strongly the Federal Reserve will commit to supporting the economy at a gathering this week.
Fed chief Ben Bernanke is due to address central bankers at an annual symposium in Jackson Hole, Wyoming, on Friday. His speech last year laid the groundwork for the Fed's $600 billion bond-buying program, to revive a sputtering U.S. economy.
While many doubt Bernanke will immediately commit to conducting the third round of quantitative easing, or QE3, investors generally expect him to stress that the central bank stands ready to act if necessary.
Judging by the recent behavior of markets, they are expecting either a stimulus package to be announced or Bernanke to elaborate on what weapons remain in his arsenal, Ben Potter, strategist at IG Markets, said.
Either way, we think the market is setting itself up for disappointment as we think it is highly unlikely a QE3 package will be unveiled. It could be a classic case of 'buy the rumor, sell the fact'.
