The FTSE 100 opened with minor losses after an uninspiring performance on Wall Street last night, with profit taking pushing heavyweight miners lower and British Airways hurt by worries over further strike action, said dealers. At 8.09 am, the FTSE 100 was 13.6 points lower at 5,304.8, while the broader indices were mixed. In the US last night, the major indices closed in the black amid thin volumes, with some support from merger news countered by another spike in crude oil prices. The DJIA ended up 10.66 points at 10,569, well below an intraday high of 10,641. The S&P 500 Index closed up 2.02 points at 1,221.73, and the Nasdaq Composite up 5.85 points at 2,141. Over in Asia, the Nikkei 225 index ended the day up 20.42 points at 12,472.93, while the Hang Seng index was down 5.01 points at 15,213.62 at midday. At 4.05 am, New York's main contract, light sweet crude for delivery in October, was trading at 65.73 usd a barrel, up eight cents from its close of 65.65 usd in the US overnight. In London, heavyweight mining stocks were knocked by profit taking after a strong rally yesterday. BHP Billiton down 7-1/2 pence at 837 and Rio Tinto off 9 pence at 2,040.
