- Gloomy Chinese, UK and Eurozone data- Rajoy denies bailout- FirstGroup sinks after West Coast disappointment.The FTSE 100 was trading broadly flat by midday on Wednesday as investors remained cautious after a raft of disappointing economic data.China's non-manufacturing purchasing managers' index (PMI) fell from 56.3 to 53.7 in September, according to the National Bureau of Statistics and China Federation of Logistics and Purchasing. China's consumer sentiment index also fell from 90.4 to 89.3 last month, its lowest level since December, according to Deutsche Boerse's MNI. Meanwhile, the UK's dominant service sector expanded in September but undershot analysts' forecasts. Markit's service sector PMI registered 52.2 down from 53.7 the month before. Analysts had pencilled in a reading of 53. In Eurozone news, the Markit Eurozone PMI Composite Output Index (which reflects a weighted-average combination of the manufacturing and services sector in the region) hit a four-month low at 46.1. Although also ahead of the flash estimate of 45.9, it still slipped from August's reading of 46.3.Spanish Prime Minister Mariano Rajoy yesterday denied claims that his country is looking to request a bailout this weekend. He said that the country had no immediate plans to ask for aid. "Uncertainty is returning to the markets at the moment as Mariano Rajoy plays his cards very close to his chest in respect to Spain's request for a bailout. While it's a foregone conclusion now that Spain will request a bailout, no one really has a clue when this is," said market analyst Craig Erlam from Alpari. "There is a general consensus that Rajoy will wait until after the regional elections on 21 October, as we saw a similar move earlier in the year, however this is only an educated guess at best. One thing that appears certain is that until we do see some progress here, we're unlikely to see many big moves in the markets," he said.FTSE 100: Sainsbury's picks up but Tesco still downAfter an earlier fall, retailing giant Sainsbury's was higher by lunchtime after saying it had outperformed the market in the second quarter, with total sales up 4.4% excluding fuel and like-for-like (LFL) sales up 1.9%.However, sector peer Tesco was still in the red after its interim results.
