- Investors risk averse ahead of elections- UK services PMI disappoints- Greece to vote on austerityNervousness ahead of the US presidential elections saw stocks head lower on Monday morning, with losses cemented by a worse-than-expected reading of service-sector activity in the UK.In regards to the elections Stateside, market analyst Craig Erlam said: "With the race so close, investors are understandably risk averse today. The outcome of the election is likely to have a significant impact on the markets, not just in the US but abroad as well. "As the world's largest economy, global sentiment usually feeds off what is happening in the US markets, as witnessed recently by the positive impact from the Fed's QE3 programme and the negative impact from the US corporate earnings season."Economic data from closer to home failed to lift sentiment this morning: the UK services purchasing managers' index (PMI) fell from 52.2 to 50.6 in October, well below the consensus esteem of 52.0 and the long-run average of 54.9. "With the rate of expansion significantly below its long-run average the services sector does not seem to have the strength to drive a strong recovery in the economy, in our view," said analyst Blerina Uruci from Barclays Research.Meanwhile, the HSBC China services PMI fell from a four-month high of 54.3 to 53.5 in October, contrasting with the official services PMI from the National Bureau of Statistics this weekend, which rose from 53.7 to 55.5.Markets will also be keeping an eye on Greece today ahead of critical parliamentary votes on austerity. Greek Prime Minister Antonis Samaras said: "We have to save the country from catastrophe...Leaving the euro would be a nightmare and we intend to avert it."
