Markets are expected to open in the red on Tuesday morning after a strong surge the day before as investors turn cautious ahead of US inflation figures out later on.City sources predict the FTSE 100 will open down 18 points from Monday's close of 6,522.2, as stocks pull back after a 1.3% jump the day before. "Yesterday's strong rebound in equity markets saw over half of last week's losses wiped out in a single session, but stopped short of getting close to the high levels seen last Monday," said Chief Market Analyst Michael Hewson from CMC Markets. "It would appear that some bargain hunting after two successive weeks of declines as well as a growing belief, possibly misplaced. that the Fed will do nothing this week saw European markets post some of the best one-day gains since October this year."Hewson said many are hoping that below-par inflation in the States will keep the Fed on hold when it meeting concludes tomorrow, even though most other data seems to be pointing in the right direction."This is why today's US consumer price index numbers could well be instructive in that regard with expectations that the November numbers could well see a rise from 1% to 1.3% on annualised basis."
