- Earnings and Eurozone concerns weigh on sentiment- BATS and IHG disappoint early on- Miners gain on upbeat Chinese dataUK stocks failed to rebound from yesterday's steep sell-off despite some upbeat economic data out from China overnight, as investors continued to digest some disappointing corporate earnings the world over."Continuing weak US corporate data with several top-tier companies projecting very challenging conditions in the months ahead and news out of Spain where Moody's downgraded several key regions to junk resulting in higher periphery yields has many investors worried that things might be taken a turn for the worse again, especially with no visible progress in the past few days what an aid package for Spain is concerned," said Markus Huber, the head of German HNW Trading at ETX Capital.HSBC's China purchasing managers' index (PMI) for October ticked higher to 49.1 points from 47.9 in September, the best reading for three months. "October's flash PMI reading continues to recover for the second month, thanks in part to a gradual improvement in the new orders index, which picked up to a six-month high," said Qu Hongbin, chief economist for HSBC Holdings PLC's China arm. Markets will also be keeping an eye on the two-day Federal Open Market Committee (FOMC) meeting in the US which comes to a close this evening. However, with no change neither in rates nor in the wording of the FOMC statement expected, "most are expecting it to be a non-event", according to ETX Capital's Huber."Overall short-term sentiment remains negative, further losses today would be considered especially damaging as many indices are near the lower band of the most recent trading range, if these major supports are being broken more losses in the next few days are likely with a change in the overall positive trend possible," Huber said.FTSE 100: BATS and IHG disappoint after Q3 updatesCigarette and tobacco giant British American Tobacco (BATS) was under pressure after organic revenue growth and volumes were worse than expected in the third quarter.
