London's benchmark index was registering decent gains by Thursday lunchtime as earlier concerns about disappointing earnings from Apple were outweighed by better-than-expected economy data from Europe and China. Investors began today's session in a cautious fashion with the FTSE 100 struggling to find direction after the world's largest tech company, Apple, missed both revenue and profit forecasts in its fiscal first quarter."This morning's headlines are largely dedicated to Apple's after-market earnings miss that saw the stock trade lower by as much as 10% in out-of-hours trade," said Matt Basi, a senior sales trader at CMC Markets."Apple bulls will be licking their wounds this morning before making a difficult decision as to whether the fall is an over-reaction, or represents the next stage of a down trend that has been in place since September of last year."However, the Footsie managed to push firmly into the blue by midday after some decent economic data.

While this still represents a contraction, the consensus forecast was for a rise to just 47.5.It is America's turn to report manufacturing figures later on, with the preliminary Markit PMI for January expected to fall from 54 to 53. Markets will also be looking out for jobless claims figures for last week, which are forecast to rise from 335,000 to 355,000.FTSE 100: Miners higher after Chinese dataAnglo American, BHP Billiton and Rio Tinto were edging higher this morning after the improved Chinese data lifted the outlook for demand.
