Stocks are expected to pull back from a six-week high on Tuesday morning as markets await the outcome of this month's Federal Reserve monetary policy meeting.Equities started the week strongly after the announcement by well-known hawk Larry Summers that he has dropped out of the race to take over Ben Bernanke's position as Fed Chairman when he steps down in January. However, investors are likely to turn nervous ahead of the conclusion of the Federal Open Market Committee (FOMC) meeting tomorrow afternoon as markets ready themselves for one of the most closely-watched US policy decisions in recent years, given rising expectations that the central bank will begin to scale back its quantitative easing programme.According to analysts at Barclays Research, the Fed is likely to taper monthly asset purchases from $85bn to $70bn this week. However, they note that the announcement of tapering by $10-15bn in itself is unlikely to move the market."We think the key to gauge the market reaction would be: 1) the Fed's updated economic forecasts, especially its forecast for end-2016 to be included for the first time; and 2) the tone in the Chairman Bernanke's press conference regarding the pace/conclusion of tapering," Barclays Research explained. City sources predict the FTSE 100 will open down 16 points from yesterday's close of 6,622.86 - this was the best close for London's benchmark index since August 2nd, when it finished the day at 6,647.87.
